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.
