illustrate

The LMH0036 clock restorer and SD SDI 4:1 input multiplexed retimes serial digital video data comply with the SMPTE 259M standard (C). LMH0036 operates at a serial data rate of 270 Mbps and also supports DVB-ASI operation at 270 Mbps. The LMH0036 includes a comprehensive 4:1 input multiplexer with a choice of re-timing of the four input data streams.

while LMH0036 retimes incoming data to suppress accumulated jitter. The recovered LMH0036 serial data rate clock and optionally provided as output. The LMH0036 has two differential outputs serial data, and the second output can be selected as a low-jitter, data-rate clock output. The controls and indicators are: serial clock or second serial data output selection, manual rate selection input, output SD indicator, lock detection output, auto/manual bypass data and output mute. Serial data input, output, and differential LVPECL compatible with serial data rate clock outputs. CML's serial data and serial data rate clock outputs drive 100Ω differential termination network use. Control logic inputs and outputs LVCMOS compatible.

The LMH0036 uses a single 3.3V power supply. Typical power consumption is 360 milliwatts. The device is available in a 48-pin LLP package.
