LMH0036数据手册集成电路（IC）的视频处理规格书PDF

描述 Description

The LMH0036 SD SDI Reclocker with 4:1 Input Multiplexer retimes serial digital video data conforming to the SMPTE 259M (C) standard. The LMH0036 operates at the serial data rate of 270 Mbps, and also supports DVB-ASI operation at 270 Mbps. The LMH0036 includes an integrated 4:1 input multiplexer for selecting one of four input data streams for retiming.
The LMH0036 retimes the incoming data to suppress accumulated jitter. The LMH0036 recovers the serial data-rate clock and optionally provides it as an output. The LMH0036 has two differential serial data outputs; the second output may be selected as a low-jitter, data-rate clock output. Controls and indicators are: serial clock or second serial data output select, manual rate select input, SD indicator output, lock detect output, auto/manual data bypass, and output mute. The serial data inputs, outputs, and serial data-rate clock outputs are differential LVPECL compatible. The CML serial data and serial data-rate clock outputs are suitable for driving 100Ω differentially terminated networks. The control logic inputs and outputs are LVCMOS compatible.
The LMH0036 is powered from a single 3.3V supply. Power dissipation is typically 360 mW. The device is housed in a 48-pin WQFN package.
