3 Gbps, HD, SD, DVB-ASI SDI Serializer and Cable Driver

with LVDS Interface

General Description

Key Specifications

The LMH0340/0040/0070/0050 SDI Serializers are part of

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

porting 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 stan-

dards. See Table 1 for details on which Standards are sup-

ported per device.

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)

Features

LVDS Interface to Host FPGA

■

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 transmis-

sion line or interface to a cable driver.

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

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 pack-

aged in a physically small 48 pin LLP package.

Applications

SDI interfaces for:

■

Video Cameras

DVRs
