LMH0046

HD/SD Multi-Rate Serial Digital Video Data Reclocker

General Description

Features

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

serial digital video standards

The LMH0046 HD/SD Multi-Rate Serial Digital Video Data

Reclocker is a monolithic integrated circuit that retimes bit-

serial digital video data conforming to the SMPTE 259M (A &

C) and SMPTE 292M standards. The LMH0046 operates at

serial data rates of 143 Mbps, 270 Mbps, 1.483 Gbps and

1.485 Gbps. The LMH0046 supports DVB-ASI operation at

270 Mbps.

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

Gbps serial data rate operation

n Supports DVB-ASI at 270 Mbps

n Single 3.3V supply operation

n 330 mW typical power consumption

n Two differential, reclocked outputs

n Choice of second reclocked output or low-jitter,

differential, data-rate clock output

n Single 27 MHz external crystal or reference clock input

n Manual rate select input

n SD/HD operating rate indicator output

n Lock Detect indicator output

n Output mute function for data and clock

n Auto/Manual reclocker bypass

The LMH0046 automatically detects the incoming data rate

and adjusts itself to retime the incoming data to suppress

accumulated jitter. The LMH0046 recovers the serial data-

rate clock and optionally provides it as an output. The

LMH0046 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 by-

pass and output mute. The serial data inputs, outputs, and

serial data-rate clock outputs are differential LVPECL com-

patible. The CML serial data and serial data-rate clock out-

puts are suitable for driving 100Ω differentially terminated

networks. The control logic inputs and outputs are LVCMOS

compatible.

n Differential LVPECL compatible serial data inputs and

outputs

n LVCMOS control inputs and indicator outputs

n 20-Pin TSSOP package

n Industrial temperature range: -40˚C to +85˚C

The LMH0046 is powered from a single 3.3V supply. Power

dissipation is typically 330 mW. The device is housed in a

20-pin TSSOP package.

Applications

n 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
