The 3G SDI SerDes evaluation system consists of: Cyclone III FPGA development board (sold separately by Altera) National SDI video and clocking daughter card (SDALTEVK) Comprehensive user manual, schematics, and bill of materials (BOM) FPGA IP Nationals daughter card, SDALTEVK, includes synthesizable FPGA source code available in both Verilog and VHDL to maximize flexibility and facilitate IP customization. The daughter card, available as an option, plugs directly into the Altera Cyclone III development board via Alteras high-speed mezzanine connector (HSMC). The SDALTEVK daughter card contains: LMH0344 Triple-rate SDI Adaptive Cable Equalizer LMH0340 Triple-rate SDI Serializer with integrated cable driver LMH0341 Triple-rate SDI deserializer with reclocked loop through LMH1981 Multi-Format Video Sync Separator LMH1982 Multi-Rate Video Clock Generator DS90CP22 2x2 LVDS Crosspoint Switch LP3878 Adjustable Low Noise LDO LM20242 PowerWise Buck Regulator The SDALTEVK supports a complete 3G-SDI signal path consisting of adaptive cable equalizer (LMH0344), deserializer with reclocked loop through (LMH0341) and serializer with integrated cable driver (LMH0340). A multi-rate sync separator (LMH1981) and clock generator (LMH1982) deliver ultra-low jitter reference clocks to the host FPGA. A 2x2 LVDS crosspoint switch (DS90CP22) acts as a reference clock selector to choose between four separate clocking options: Recovered clock from LMH0341 deserializer Genlock from analog reference, LMH1981 sync separator and LMH1982 clock generator Local clock generation from LMH1982 in free-run mode External clock via SMA connector
