WHAT IS DRIVING THE 3G-SDI ADOPTION  Improved jitter attenuation and improved jitter margins mean that there is more tolerance for cascaded SDI signals.  Longer cable distances using coaxial cables means less need to install fiber optics to go the longer distances.  Better performance even at lower data rates, 3G can deliver longer cable lengths and reduced bit error rates.  Improved system reliability with 3G covering both SD/HD data rates then there is a far simplified plant design with less mix of components.

The DACs have built-in high performance, rail-to-rail, output buffers and are guaranteed monotonic.The LTC2656-L has a full-scale output of 2.5V with the integrated 10ppm/°C reference and operates from a single 2.7V to 5.5V supply. The LTC2656-H has a full-scale output of 4.096V with the integrated reference and operates from a 4.5V to 5.5V supply. Each DAC can also operate with an external reference, which sets the DAC full-scale output to two times the external reference voltage. These DACs communicate via a SPI/MICROWIRE™ compatible 4-wire serial interface which operates at clock rates up to 50MHz. The LTC2656 incorporates a power-on reset circuit that is controlled by the PORSEL pin. If PORSEL is tied to GND the DACs reset to zero-scale. If PORSEL is tied to VCC, the DACs reset to mid-scale.

KSZ8873: 3-port Ethernet Switch A new generation of low port count, costsensitive and power-efficient 10/100Mbps switch on a chip ICs

The KSZ8873 family is designed to support the GREEN requirement in today’s switch systems. Advanced power management schemes include hardware and software power down, as well as the energy detect mode that shuts downs the transceiver when a port is idle. KSZ8873MLL, KSZ8873RLL, and KSZ8873FLL also offer the by-pass mode, which enables system-level power savings. In this mode, the processor connected to the switch through the MII interface can be shut down without impacting the normal switch operation.
