LMH0046

HD/SD SDI Reclocker with Dual Differential Outputs

General Description

Features

The LMH0046 HD/SD SDI Reclocker retimes serial digital

video data conforming to the SMPTE 292M and SMPTE

259M (A & C) 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.

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

The LMH0046 automatically detects the incoming data rate

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

cumulated 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 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.

330 mW typical power consumption

Two differential, reclocked outputs
