SNLS248J –APRIL 2007–REVISED APRIL 2013  
3 Gbps HD/SD SDI Reclocker with Dual Differential Outputs  
Check for Samples: LMH0346

FEATURES  
DESCRIPTION  
The LMH0346 3 Gbps HD/SD SDI Reclocker retimes  
serial digital video data conforming to the SMPTE  
424M, SMPTE 292M, and SMPTE 259M (C)  
standards. The LMH0346 operates at serial data  
rates of 270 Mbps, 1.483 Gbps, 1.485 Gbps, 2.967  
Gbps, and 2.97 Gbps. The LMH0346 supports DVB-  
ASI operation at 270 Mbps.

Operation

•
•
Supports DVB-ASI at 270 Mbps  
Single 3.3V Supply Operation  
The LMH0346 automatically detects the incoming  
data rate and adjusts itself to retime the incoming  
data to suppress accumulated jitter. The LMH0346  
recovers the serial data-rate clock and optionally  
provides it as an output. The LMH0346 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 clock outputs are  
differential LVPECL compatible. The CML serial data  
and serial clock outputs are suitable for driving 100Ω  
differentially terminated networks. The control logic  
inputs and outputs are LVCMOS compatible.
