LMH0026  
SD SDI Reclocker with Dual Differential Outputs  
General Description  
Features  
The LMH0026 SD SDI Reclocker retimes serial digital video  
data conforming to the SMPTE 259M (C) standard. The  
LMH0026 operates at the serial data rate of 270 Mbps and  
also supports DVB-ASI operation at 270 Mbps.  
Supports SMPTE 259M (C) serial digital video standard  
Supports 270 Mbps serial data rate operation  
Supports DVB-ASI at 270 Mbps  
Single 3.3V supply operation  
The LMH0026 retimes the incoming data to suppress accu-  
mulated jitter. The LMH0026 recovers the serial data-rate  
clock and optionally provides it as an output. The LMH0026  
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, 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 100differentially terminated  
networks. The control logic inputs and outputs are LVCMOS  
compatible.  
330 mW typical power consumption  
Two differential, reclocked outputs  
Choice of second reclocked output or low-jitter,  
differential, data-rate clock output  
Single 27 MHz external crystal or reference clock input  
Lock Detect indicator output  
Output mute function for data and clock  
Auto/Manual reclocker bypass  
Differential LVPECL compatible serial data inputs and  
outputs  
LVCMOS control inputs and indicator outputs  
20-Pin e-TSSOP package  
The LMH0026 is powered from a single 3.3V supply. Power  
dissipation is typically 330 mW. The device is housed in a 20-  
pin e-TSSOP package.  
Industrial temperature range: -40°C to +85°C  
Footprint compatible with the LMH0046 and LMH0346  
Applications  
SDTV serial digital video interfaces for:  
Digital video routers and switchers  
Digital video processing and editing equipment  
DVB-ASI equipment  
Video standards and format converters
