XRT81L27 Description
The XRT81L27 is an optimized seven-channel, analog, 3.3V, line interface unit, fabricated using low power CMOS technology. The device contains seven independent E1 channels, including data and clock recovery circuits. It is primarily targeted towards the SDH multiplexers that acmodate TU12 Tributary Unit Frames.
