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
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
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.
