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

Loopthrough and LVDS Interface

General Description

Key Specifications

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.

Output compliant with SMPTE 259M-C, SMPTE 292M,

SMPTE 424M and DVB-ASI (See Table 1)

■

Typical power dissipation: 590 mW (loopthrough disabled,

3G datarate)

0.6 UI Minimum Input Jitter Tolerance

Features

5–bit LVDS Interface

■

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.

No external VCO or clock required

Reclocked serial loopthrough with Cable Driver

Powerdown Mode

3.3V SMBus configuration interface

Small 48 pin LLP package

Industrial Temperature range:-40°C to +85°C

Applications

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.
