Hd/sd Sdi Reclocker With 4:1 Input Multiplexer - National SemiconductorThe LMH0056 HD/SD SDI Reclocker with 4:1 Input Multi-
plexer is a monolithic integrated circuit that retimes bit-serial
digital Video data conforming to the SMPTE 259M (A & C)
and SMPTE 292M standards. The LMH0056 operates at
serial data rates of 143 Mbps, 270 Mbps, 1.483 Gbps and
1.485 Gbps. The LMH0056 supports DVB-ASI operation at
270 Mbps. The LMH0056 includes an integrated 4:1 input
multiplexer for selecting one of four input data streams for
retiming.
The LMH0056 automatically detects the incoming data rate
and adjusts itself to retime the incoming data to suppress
accumulated jitter. The LMH0056 recovers the serial data-
rate Clock and optionally provides it as an output. The
LMH0056 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/HD rate
indicator output, lock detect output, auto/manual data by-
pass and output mute. The serial data inputs, outputs, and
serial data-rate Clock outputs are differential LVPECL com-
patible. The CML serial data and serial data-rate Clock out-
puts are suitable for driving 100 differentially terminated
networks. The control Logic inputs and outputs are LVCMOS
compatible.
The LMH0056 is powered from a single 3.3V supply. Power
dissipation is typically 350 mW. The device is housed in a
48-pin LLP package. By National Semiconductor Corporation
