DESCRIPTION
The LMH0340/0040/0070/0050 SDI Serializers are
part of TI’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 Table 1 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 WQFN package.
