LMH0026

SD SDI Reclocker with Dual Differential Outputs

General Description

Features

The LMH0026 SD SDI Reclocker retimes serial digital video

data conforming to the SMPTE 259M (C) standard. The

LMH0026 operates at the serial data rate of 270 Mbps and

also supports DVB-ASI operation at 270 Mbps.

Supports SMPTE 259M (C) serial digital video standard

Supports 270 Mbps serial data rate operation

Supports DVB-ASI at 270 Mbps

■

Single 3.3V supply operation

The LMH0026 retimes the incoming data to suppress accu-

mulated jitter. The LMH0026 recovers the serial data-rate

clock and optionally provides it as an output. The LMH0026

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, SD indicator output, lock detect output, auto/manual

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

and serial data-rate clock outputs 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 inputs and outputs are LVCMOS

compatible.

330 mW typical power consumption

Two differential, reclocked outputs

Choice of second reclocked output or low-jitter,

differential, data-rate clock output

Single 27 MHz external crystal or reference clock input

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

20-Pin e-TSSOP package

■

The LMH0026 is powered from a single 3.3V supply. Power

dissipation is typically 330 mW. The device is housed in a 20-

pin e-TSSOP package.

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

Footprint compatible with the LMH0046 and LMH0346

Applications

SDTV serial digital video interfaces for:

■

Digital video routers and switchers

Digital video processing and editing equipment

DVB-ASI equipment

—

Video standards and format converters
