Texas Instruments' 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" to 60" of FR4 trace length. Each input also includes independent signal detection with a programmable threshold.
