Features LVDS Interface to Host FPGA No external VCO or clock ref required Integrated Variable Output Cable Driver 3.3V SMBus configuration interface Integrated TXCLK PLL cleans clock noise Small 48pin LLP package Industrial Temperature range:-40°C to 85°C Description The LMH0340/0040/0070/0050 SDI Serializers are part of National’s family of FPGA-Attach SER/DES products supporting 5-bit LVDS interfaces with FPGAs. An FPGA Host will format data with supplied IP such that the output of the LMH0340 is compliant with the requirements of DVB-ASI, SMPTE 259M-C, SMPTE 292M and SMPTE 424M standards. See for details on which Standards are supported per device. The interface between the SER (Serializer) and the FPGA consists of a 5 bit wide LVDS data bus, an LVDS clock and an SMBus interface. The LMH0340/0040/0070 SER devices include an integrated cable driver which is fully compliant with all of the SMPTE specifications listed above. The LMH0050 has a CML output driver that can drive a differential transmission line or interface to a cable driver. The FPGA-Attach SER/DES family is supported by a suite of IP which allows the design engineer to quickly develop video applications using the SER/DES products. The SER is packaged in a physically small 48 pin LLP package. Key Specification Output compliant with SMPTE 424M, SMPTE 292M, SMPTE 259M-C and DVB-ASI (See Table 1) Typical power dissipation: 440 mW 30 ps typical output jitter (HD, 3G) Applications SDI interfaces for: Video Cameras DVRs Video Switchers Video Editing Systems

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
