LMH0376

3 Gbps HD/SD SDI Low Power Reclocker with Integrated Eye Monitor

and 4:1 Input Mux

Check for Samples: LMH0376

FEATURES

DESCRIPTION

The LMH0376 3 Gbps HD/SD SDI Low Power

Reclocker with Integrated Eye Monitor and 4:1 Input

Mux retimes serial digital video data conforming to

the SMPTE ST 424, SMPTE ST 292, and SMPTE ST

259-C standards. The reclocker operates at serial

data rates of 125 Mbps, 270 Mbps, 1.4835 Gbps,

1.485 Gbps, 2.967 Gbps, and 2.97 Gbps.

•

SMPTE ST 424, SMPTE ST 292, and SMPTE ST

259-C Compliant

•

Supports 125 Mbps, 270 Mbps, 1.4835 Gbps,

1.485 Gbps, 2.967 Gbps, and 2.97 Gbps Serial

Data Rate Operation

•

Supports DVB-ASI at 270 Mbps and MADI at

125 Mbps

The LMH0376 automatically detects the incoming

data rate and retimes the data to suppress

accumulated jitter. The reclocker recovers the serial

data-rate clock and optionally provides it as an

output.

100 mW Typical Power Consumption (145 mW

with Both Output Drivers Enabled)

Integrated 4:1 Multiplexed Input with 0-60” FR4

Equalizer and Independent Signal Detect on

Each Channel

The LMH0376 includes an integrated 4:1 input

multiplexer for selecting one of four input data

streams for retiming. Each of the four inputs has an

FR4 equalizer capable of equalizing 0-60” of FR4

trace length. Each input also includes independent

signal detection with a programmable threshold.

•

Two Differential, Reclocked Outputs with

Option of Recovered Clock

Output De-Emphasis to Compensate for up to

40” of FR4 Trace Losses

•

64 x 64 Point Eye Opening Monitor

The LMH0376 has two differential serial data outputs

and offers flexibility in selecting the output signals

between the reclocked data, recovered clock,

bypassed data, or the bypassed data from an

independently selected input channel. The output

drivers offer programmable de-emphasis for up to 40”

of FR4 trace losses, in addition to programmable

common mode voltage and swing for flexible

interfacing.

27 MHz External Reference or Reference-less

Operation

•

Internally Terminated 100Ω Inputs with Rail-to-

Rail Input Common Mode Voltage

Internally Terminated 100Ω LVDS Outputs with

Programmable Output Common Mode Voltage

and Swing

•

Single 2.5V Supply Operation

The LMH0376 provides a 64 x 64 point eye monitor

for analyzing the eye quality of the incoming signal.

Power Save Mode with Device Power Down

Control

The LMH0376 supports two modes of operation. In

pin mode, the LMH0376 operates with control pins to

set its operating state, and is footprint compatible with

the LMH0356 reclocker. In SPI mode, an optional SPI

serial interface can be used to configure and monitor

APPLICATIONS

•

SMPTE ST 424, SMPTE ST 292, and SMPTE ST

259 Serial Digital Interfaces

•

Broadcast Video Routers, Switchers, and

Distribution Amplifiers
