LMH0056  
HD/SD SDI Reclocker with 4:1 Input Multiplexer  
General Description  
Features  
■
The LMH0056 HD/SD SDI Reclocker with 4:1 Input Multi-  
plexer retimes serial digital video data conforming to the  
SMPTE 292M and SMPTE 259M (A & C) 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.  
Supports SMPTE 292M and SMPTE 259M (A & C) serial  
digital video standards  
Supports 143 Mbps, 270 Mbps, 1.483 Gbps, and 1.485  
Gbps serial data rate operation

Supports DVB-ASI at 270 Mbps  
Single 3.3V supply operation

360 mW typical power consumption  
Integrated 4:1 multiplexed input  
Two differential, reclocked outputs  
The LMH0056 automatically detects the incoming data rate  
and adjusts itself to retime the incoming data to suppress ac-  
cumulated 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 bypass and output mute.  
The serial data inputs, outputs, and serial data-rate clock out-  
puts 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 in-  
puts and outputs are LVCMOS compatible.  
Choice of second reclocked output or low-jitter,  
differential, data-rate clock output  
Single 27 MHz external crystal or reference clock input  
Manual rate select input

■
The LMH0056 is powered from a single 3.3V supply. Power  
dissipation is typically 360 mW. The device is housed in a 48-  
pin LLP package.  
Industrial temperature range: -40°C to +85°C  
Applications  
SDTV/HDTV serial digital video interfaces for:
