The CS61304A 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 CS61304A is a pin-compatible replacement for the LXT304A. The receiver uses a digital Delay-Locked-Loop (DLL) which is continuously calibrated from a crystal reference to provide stability and jitter tolerance. The CS61304A has a receiver jitter attenuator optimized for T1 CPE applications subject to AT&T 62411 and E1 ISDN PRI applications. The transmitter features internal pulse shaping and a low impedance output stage allowing the use of external resistors for transmitter impedance matching.
