ISE Design Suite 11 – Complex Design Made Logical Logic

Domain-specific Methodology for Targeted Design Platforms The ISE® Design Suite 11 is truly a next-generation advance in Xilinx FPGA design environments, offering unprecedented benefits in three distinct but interrelated categories; productivity, time to design completion, and quality of results. In addition, the ISE Design Suite provides a tighter connection between embedded and DSP flows to enable integration of designs that contain embedded, DSP, IP, and user blocks in one system. To better serve users familiar with differing design environments, the new ISE Design Suite 11 provides specific accommodations for designers ranging from the push-button user to the ASIC designer. Instead of addressing the problem in terms of individual fixed tools, the ISE Design Suite targets the required or preferred methodology for each user to better address their specific needs with the appropriate design flow. At this level, the design language may change from HDL (VHDL/Verilog) to C, C++, Matlab® software from The Mathworks, or other higher level languages which are more widely used by these designers. Likewise, design abstraction moves up from the block or component level to the system level. The result is a methodology and complete design flow tailored to each user profile that provides complete design creation, design implementation, and design verification. ISE Design Suite 11 will be offered in four different configurations aligned to your preferred methodology—logic, embedded, DSP or system design.

PCI Express

GN4124 4-Lane PCI Express®-to-Local Bus Bridge Complete Solution for Developing a PCI Express Endpoint Application The GN4124 is a four lane PCI Express-to-local bus endpoint bridge that is designed to work as a companion for FPGA devices to provide a complete bridging solution for general applications. In addition to a 4-lane PCI Express compliant PHY interface, the GN4124 also contains the link and transaction layers, and an applications interface that is ideally suited to FPGA interfacing using a small number of pins.

FPGA

User Application

Since the PCI Express transaction/link IP is hard-wired into the GN4124, there is no need to license PCIe IP. The level of integration and very low power operation of the GN4124 make it an ideal alternative to using a PIPE PHY, where IP licensing and the cost of FPGA resources and power consumption are unattractive by comparison. Using the GN4124 allows FPGA resources to be spent on what differentiates the product rather than on implementing the PCI Express protocol.

www.Gennum.com/PCIe

Live on Power-up Since the GN4124 contains a complete type 0 PCI configuration space, it is live on power-up so that a plug-and-play BIOS can auto-detect it and enumerate it without an attached FPGA having to be configured. FPGA On-the-Fly Configuration Loader An FPGA configuration bitstream may be downloaded from the host system over PCIe to the attached FPGA using the on-chip FPGA Configuration Loader (FCL). This eliminates the expense of a dedicated FPGA ROM and makes on-the-fly reconfiguration and firmware upgrades simple. Any application requiring dynamic reconfiguration or firmware upgrades over PCIe can benefit from the use of the GN4124 as a companion device regardless of the size or type of FPGA device used. Local Bus Interface The local bus interface uses dual data rate SSTL I/O to accomplish very high data rates using the fewest possible pins. A single data rate clock is used for SSTL control signals and separate dual data rate source synchronous clocking is used for the DDR SSTL data. The SDR control signals operate at up to 200MHz and the DDR I/O operate at up to 400MT/s across 16 bits using a 200MHz DDR clock. This provides 800MB/s in each direction. Cost Free IP Gennum provides a complete solution around the GN4124 to accelerate your design cycle. This includes full documentation, an evaluation board with schematics, FPGA local bus interface IP, example FPGA application code, driver software, and example application software – all provided in source format. All source code is provided cost/royalty free for use with the GN4124. Single Lane Version Available For applications that don’t require the full performance of the GN4124, the GN4121 is a lower cost single lane version. It features the same local bus interface only operating at lower frequency. It is also software and footprint compatible with the GN4124, allowing a single design to be leveraged into multiple end products.

From High Voltage to 0.5, 1 or 2 Amps of Brightness in a Single Design

The XRP7603, XRP7604 and SP7600 are a series of non-synchronous voltage mode PWM step down converters optimized to drive a string of high power LEDs at respectively up to 500mA, 1A and 2A of continuous current. A wide 4.5V to 29V input voltage range allows for single supply operations from industry standard 5, 12 or 24V power rails. A 1.2MHz constant operating frequency allows for small external components selection while an internal control loop compensation reduces the overall component count and solution footprint. With a 2.5% output setpoint accuracy and an input feedforward control, these devices improve stability as well as typical transient and regulation responses. Dimming and shutdown mode is provided via an enable function when required. A programmable over current and under voltage lock out protection insures safe operations under abnormal operating conditions. The XRP7603, XRP7604 and SP7600 are pin-to-pin compatible providing the most fl exibility when designing evolutive and scalable lighting solutions and are offered in a compact thermally enhanced RoHS compliant “green”/halogen free 8-pin SO package.

Power & Battery Management

0.5A/1A/2A 29V Non-Synchronous Buck High Power LED Drivers

LTC3605 - a high efficiency, 15V, 4MHz synchronous buck regulator that uses a constant frequency controlled on-time, current mode architecture. The LTC®3605 is a high efficiency, monolithic synchronous buck regulator using a phase lockable controlled on-time constant frequency, current mode architecture. PolyPhase operation allows multiple LTC3605 regulators to run out of phase while using minimal input and output capacitance. The operating frequency is programmable from 800kHz to 4MHz with an external resistor. The high frequency capability allows the use of small surface mount inductors. For switching noise sensitive applications, it can be externally synchronized from 800kHz to 4MHz. The PHMODE pin allows user control of the phase of the outgoing clock signal. The unique constant frequency/controlled ontime architecture is ideal for high step-down ratio applications that are operating at high frequency while demanding fast transient response. Two internal phase-lock loops synchronize the internal oscillator to the external clock and also servos the regulator on-time to lock on to either the internal clock or the external clock if it’s present. The LTC3605 uses internal N-channel switches with RDS(ON)s of only 35mΩ and 70mΩ to deliver efficiencies as high as 96%. Its low minimum on-time allows low duty cycle operation at high switching frequencies. The LTC3605’s PolyPhase® operation (up to 12 phases) allows multiple regulators to be cascaded, running out of phase to minimize input and output capacitance. Current mode operation offers fast transient response while simplifying compensation. Additional features include output tracking and a shutdown current of only 15µA. The LTC3605EUF is available in a 4mm x 4mm QFN-24. Pricing starts at $4.25 each in 1,000-piece quantities

Next Generation, 120 kHz Bandwidth, 50-200 A Current Sensor with 100 µΩ, Integrated Current Conductor for Reduced Power Loss

The ACS758 family of current sensors provides economical and precise solutions for AC or DC current sensing. Typical applications include motor control, load detection and management, power supply and DC-to-DC converter control, inverter control, and over-current fault detection. The device consists of a precise, low-offset linear Hall sensor circuit with a copper conduction path located near the Hall sensor die. Applied current flowing through this copper conduction path generates a magnetic field which is sensed by the integrated Hall IC and converted into a proportional voltage. Device accuracy is optimized through the close proximity of the magnetic signal to the Hall transducer, and through the integration of a high performance ferromagnetic core into Allegro’s custom CB package. A precise, proportional voltage is provided by the lowoffset, chopper-stabilized BiCMOS Hall IC, which is programmed for accuracy at the factory. High level immunity to current conductor dV/dt and stray electric fields, offered by Allegro proprietary integrated shield technology, guarantees low output ripple and low offset drift in high-side, high voltage applications. The output of the device has a positive slope (>VCC / 2) when an increasing current flows through the primary copper conduction path (from terminal 4 to terminal 5), which is the path used for current sensing. The internal resistance of this conductive path is 100 μΩ typical, providing low power loss. The thickness of the copper conductor allows survival of the device at up to 5x over-current conditions. The terminals of the conductive path are electrically isolated from the sensor leads (pins 1 through 3). This allows the ACS758 family of sensors to be used in applications requiring electrical isolation without the use of opto-isolators or other costly isolation techniques. The device is fully calibrated prior to shipment from the factory. The ACS758 family is lead (Pb) free. All leads are plated with 100% matte tin, and there is no Pb inside the package. The heavy gauge leadframe is made of oxygen-free copper.
