The CS61577 is a drop-in replacement for the CS61574, and 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 CS61577 supports processor-based or standalone operation and interfaces with industry standard T1 and E1 framers. The receiver uses a digital Delay-Locked-Loop (DLL) which is continuously calibrated from a crystal reference to provide excellent stability and jitter tolerance. The receiver includes a jitter attenuator optimized for minimum delay in switching and transmission applications. The transmitter provides internal pulse shaping to ensure compliance with T1 and E1 pulse template specifications. ( ) = Pin Function in Host Mode ( ) = Pin Function in Extended Hardware Mode
