3 Gbps HD/SD SDI Low Power Reclocker
General Description
The LMH0336 3 Gbps HD/SD SDI Low Power Reclocker re-
times serial digital video data conforming to the SMPTE
424M, SMPTE 292M, and SMPTE 259M-C standards. The
reclocker operates at serial data rates of 270 Mbps, 1.4835
Gbps, 1.485 Gbps, 2.967 Gbps, and 2.97 Gbps.
The LMH0336 automatically detects the incoming data rate
and retimes the data to suppress accumulated jitter. The re-
clocker recovers the serial data rate clock and optionally
provides it as an output.
The LMH0336 input has an FR4 equalizer capable of equal-
izing 0-40” of FR4 trace length. The reclocker has two differ-
ential serial data outputs; the second output may be selected
as the recovered clock.
