LMH0346

3 Gbps HD/SD SDI Reclocker with Dual Differential Outputs

General Description

Features

The LMH0346 3 Gbps HD/SD SDI Reclocker retimes serial

digital video data conforming to the SMPTE 424M, SMPTE

292M, and SMPTE 259M (C) standards. The LMH0346 op-

erates at serial data rates of 270 Mbps, 1.483 Gbps, 1.485

Gbps, 2.967 Gbps, and 2.97 Gbps. The LMH0346 supports

DVB-ASI operation at 270 Mbps.

Supports SMPTE 424M, SMPTE 292M, and SMPTE

■

259M (C) serial digital video standards

Supports 270 Mbps, 1.483 Gbps, 1.485 Gbps, 2.967

Gbps, and 2.97 Gbps serial data rate operation

■

Supports DVB-ASI at 270 Mbps

■

Single 3.3V supply operation

The LMH0346 automatically detects the incoming data rate

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

cumulated jitter. The LMH0346 recovers the serial data-rate

clock and optionally provides it as an output. The LMH0346

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 clock outputs are

differential LVPECL compatible. The CML serial data and se-

rial clock outputs are suitable for driving 100Ω differentially

terminated networks. The control logic inputs and outputs are

LVCMOS compatible.

370 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

■

Manual or automatic 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

The LMH0346 is powered from a single 3.3V supply. Power

dissipation is typically 370 mW.

LVCMOS control inputs and indicator outputs

■

20-pin e-TSSOP or 24-pin LLP package

The device is available in two space–saving packages: a 6.5

X 4.4 mm 20-pin e-TSSOP and an even more space–efficient

5 X 4 mm 24-pin LLP package.

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

Footprint compatible with the LMH0046

andLMH0026 (e-TSSOP package)

Applications

SDTV/HDTV and 3 Gbps serial digital video interfaces for:

■

Digital video routers and switchers

Digital video processing and editing equipment

DVB-ASI equipment

—

Video standards and format converters
