CS61577

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 5 V supply. The CS61577 supports processor-based or standalone operation and interfaces with industry-standard T1 and E1 framers.

The receiver CS61577 uses a digital DLL (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 CS61577 provides internal pulse shaping to ensure compliance with T1 and E1 pulse template specifications.
