The LMH0346 3 Gbps HD/SD SDI Reclocker reTImes serialdigital video data conforming to the SMPTE 424M, SMPTE292M, and SMPTE 259M (C) standards. The LMH0346 operatesat serial data rates of 270 Mbps, 1.483 Gbps, 1.485Gbps, 2.967 Gbps, and 2.97 Gbps. The LMH0346 supportsDVB-ASI operaTIon at 270 Mbps.The LMH0346 automaTIcally detects the incoming data rateand adjusts itself to reTIme the incoming data to suppress accumulatedjitter. The LMH0346 recovers the serial data-rateclock and optionally provides it as an output. The LMH0346has two differential serial data outputs; the second output maybe selected as a low-jitter, data-rate clock output. Controlsand indicators are: serial clock or second serial data outputselect, manual rate select input, SD/HD rate indicator output,lock detect output, auto/manual data bypass and output mute.The serial data inputs, outputs, and serial clock outputs aredifferential LVPECL compatible. The CML serial data and serialclock outputs are suitable for driving 100Ω differentiallyterminated networks. The control logic inputs and outputs areLVCMOS compatible.
