The LMH0340/0040/0070/0050 SDI Serial is part of National Semiconductor's FPGA-Connected SER/DES support 5-bit LVDS interface product line with FPGAs. An FPGA host will format the IP provided by the output of such LMH0340 data that is compatible with the requirements of the DVB-ASI, SMPTE 259M-C, SMPTE 292M and SMPTE 424M standards. see For details, the standard is per-device support.

The SER (Serial) and FPGA interfaces between consist of a 5-bit wide LVDS data bus, an LVDS clock, and an SMBus interface. The LMH0340/0040/0070 SER device includes an integrated cable driver, which is fully compliant with the SMPTE specifications listed above. LMH0050 has a CML output driver that can drive a differential transmission line or an interface cable driver.

The FPGA's connectivity to the SER/DES series supports IP protocols, allowing design engineers to quickly develop SER/DES products for video applications. The SER is packaged in a small 48-pin LLP package.

Key specifications:

• Output compatible with SMPTE 424M, SMPTE 292M, SMPTE 259M-C, and DVB-ASI (see Table 1)
• Typical power consumption: 440 milliwatts
• 30 ps typical output jitter (HD, 3G)
