T1/E1 REPLACEMENT FOR LEVEL ONE LXT305A

The CS61535A combines the complete analog transmit and receive line interface for T1 or E1 applications in a low power, 28-pin device operating from a +5V supply. The device features a transmitter jitter attenuator making it ideal for use in asynchronous multiplexor systems with gapped transmit clocks. The CS61535A provides a matched, constant impedance output stage to insure signal quality on mismatched, poorly terminated lines. The IC uses a digital Delay-Locked-Loop clock and data recovery circuit which is continuously calibrated from a crystal reference to provide excellent stability and jitter tolerance.
