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 lowjitter,

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 datarate

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.
