.. CS61577 T1/E1 Line Interface Features General Description The CS61577 is a drop-in replacement for the CS61574, and bines the plete 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 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...
