产品描述

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.

The LMH0026 retimes the incoming data to suppress accumulated 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 100? differentially terminated networks. The control logic inputs and outputs are LVCMOS compatible.

The LMH0026 is powered from a single 3.3V supply. Power dissipation is typically 330 mW. The device is housed in a 20-pin HTSSOP package.
