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.

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.

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.

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.

The LMH0376 provides a 64 x 64 point eye monitor for analyzing the eye quality of the incoming signal.

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 multiple LMH0376 devices in a daisy-chain configuration.

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.
