Description

The AK2540 is the quad short haul T1 transceiver for asynchronous applications, such as M13 MUX, etc. It includes Transmitter, Clock and Data Recovery, Jitter Attenuator, LOS Detector,Driver Failure Monitor, Control Circuits, etc. in one LQFP-144 package. Internally generated transmit pulse provides the appropriate pulse shape for line length ranging from 0 to 655 feet from a DSX-1 cross connect.
