LMH0056

HD/SD SDI Reclocker with 4:1 Input Multiplexer

General Description

Features

■

The LMH0056 HD/SD SDI Reclocker with 4:1 Input Multi-

plexer retimes serial digital video data conforming to the

SMPTE 292M and SMPTE 259M (A & C) standards. The

LMH0056 operates at serial data rates of 143 Mbps, 270

Mbps, 1.483 Gbps and 1.485 Gbps. The LMH0056 supports

DVB-ASI operation at 270 Mbps. The LMH0056 includes an

integrated 4:1 input multiplexer for selecting one of four input

data streams for retiming.

Supports SMPTE 292M and SMPTE 259M (A & C) serial

digital video standards

Supports 143 Mbps, 270 Mbps, 1.483 Gbps, and 1.485

Gbps serial data rate operation

■

Supports DVB-ASI at 270 Mbps

Single 3.3V supply operation

■

360 mW typical power consumption

Integrated 4:1 multiplexed input

Two differential, reclocked outputs

The LMH0056 automatically detects the incoming data rate

and adjusts itself to retime the incoming data to suppress ac-

cumulated jitter. The LMH0056 recovers the serial data-rate

clock and optionally provides it as an output. The LMH0056

has two differential serial data outputs; the second output may

be selected as a low-jitter, data-rate clock output. Controls

and indicators are: serial clock or second serial data output

select, manual rate select input, SD/HD rate indicator output,

lock detect output, auto/manual data bypass and output mute.

The serial data inputs, outputs, and serial data-rate clock out-

puts are differential LVPECL compatible. The CML serial data

and serial data-rate clock outputs are suitable for driving

100Ω differentially terminated networks. The control logic in-

puts and outputs are LVCMOS compatible.

Choice of second reclocked output or low-jitter,

differential, data-rate clock output

Single 27 MHz external crystal or reference clock input

Manual rate select input

■

SD/HD operating rate indicator output

Lock Detect indicator output

Output mute function for data and clock

Auto/Manual reclocker bypass

Differential LVPECL compatible serial data inputs and

outputs

LVCMOS control inputs and indicator outputs

48-Pin LLP package

■

The LMH0056 is powered from a single 3.3V supply. Power

dissipation is typically 360 mW. The device is housed in a 48-

pin LLP package.

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

Applications

SDTV/HDTV serial digital video interfaces for:

■

Digital video routers and switchers

Digital video processing and editing equipment

DVB-ASI equipment

—

Video standards and format converters
