LMH0341, LMH0041, LMH0071, LMH0051

3 Gbps, HD, SD, DVB-ASI SDI Deserializer with

Loopthrough and LVDS Interface

General Description

The LMH0341/0041/0071/0051 SDI Deserializers are part of

National’s family of FPGA-Attach SER/DES products sup-

porting 5-bit LVDS interfaces with FPGAs. When paired with

a host FPGA the LMH0341 automatically detects the incom-

ing 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 con-

sists 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 inte-

grated 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 LLP package.
