illustrate

The LMH0026 serial digital video data retimes of the SD SDI clock restorer complies with the SMPTE 259M(C) standard. The LMH0026 operates at a serial data rate of 270 Mbps while also supporting DVB-ASI operation at 270 Mbps.

The LMH0026 retimes incoming data to suppress accumulated jitter. The recovered LMH0026 serial data rate clock and selectively provided as output. There are two different LMH0026 serial data outputs, and the second output can be selected as a low jitter, data rate clock output. The controls and specifications are: serial clock or second serial data output selection, SD output indicator, lock detection output, auto/manual bypass data and output mute. Differential LVPECL compatible with serial data input, output and serial data rate clock output. The CML's serial data and serial data rate clock outputs drive a 100Ω differential termination network use. Control logic input and output LVCMOS compatible.

The LMH0026 uses a single 3.3V power supply. Typical power consumption is 330 milliwatts. The device is housed in a 20-pin E-TSSOP package.
