DESCRIPTION

The LMH0341/0041/0071/0051 SDI Deserializers are

part of TI’s family of FPGA-Attach SER/DES products

supporting 5-bit LVDS interfaces with FPGAs. When

paired with a host FPGA the LMH0341 automatically

detects the incoming data rate and decodes the raw

5-bit data words compliant to any of the following

standards: DVB-ASI, SMPTE 259M, SMPTE 292M,

or SMPTE 424M. See Table 1 for details on which

Standards are supported per device.

The interface between the LMH0341 and the host

FPGA consists of a 5-bit wide LVDS bus, an LVDS

clock and an SMBus interface. No external VCOs or

clocks are required. The LMH0341 CDR detects the

frequency from the incoming data stream, generates

a clean clock and transmits both clock and data to

the host FPGA. The LMH0341, LMH0041 and

LMH0071 include a serial reclocked loopthrough with

integrated SMPTE compliant cable driver. Refer to

Table 1 for a complete listing of single channel

deserializers offered in this family.

The FPGA-Attach SER/DES product family is

supported by a suite of IP which allows the design

engineer to quickly develop video applications using

the SER/DES products. The product is packaged in a

physically small 48 pin WQFN package.
