... ASAHI KASEI The AK2546 is the 7 channel short haul T1 transceiver for a SONET MUX, M13 MUX, etc. It includes seven independent transmitters, clock and data recovery, LOS detector, control circuit in one LQFP-144 package which saves space, power consumption and the board design time. Internally generated transmit pulse provides the appropriate pulse shape for line length ranging from 0 to 655 feet from a DSX-1 cross connect ...
