DESCRIPTION

The LMH0366 3 Gbps HD/SD SDI Low Power

Reclocker with Integrated Eye Monitor 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.

The LMH0366 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.

The LMH0366 input has an FR4 equalizer capable of

equalizing 0-60” of FR4 trace length, and also

includes signal detection with a programmable

threshold.

The LMH0366 has two differential serial data outputs and offers flexibility in selecting the output signals

between the reclocked data, recovered clock, or

bypassed data. 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.

The LMH0366 provides a 64 x 64 point eye monitor

for analyzing the eye quality of the incoming signal.

The LMH0366 supports two modes of operation. In

pin mode, the LMH0366 operates with control pins to

set its operating state. In SPI mode, an optional SPI

serial interface can be used to configure and monitor

multiple LMH0366 devices in a daisy-chain

configuration.
