CS61305A

CS61305A T1/E1 Line Interface Features General Description The CS61305A 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 CS61305A is a pin-compatible replacement for the LXT305A in most applications. The CS61305A provides a transmitter jitter attenuator making it ideal for use in asynchronous multiplexor systems with gapped transmit clocks. The transmitter features internal pulse shaping and a low impedance output stage allowing the use of external resistors for transmitter impedance matching. The receiver 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.
