CS61575

CS61574A CS61575 T1/E1 Line Interface Features Provides Analog Transmission Line Interface for T1 and E1 Applications Provides Line Driver, Jitter Attenuator and Clock Recovery Functions Fully Compliant with AT&T 62411 Stratum 4 Jitter Requirements Low Power Consumption (typically 175 mW) B8ZS/HDB3/AMI Encoder/Decoder 14 dB of Transmitter Return Loss General Description The CS61574A and CS61575 combine 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. Both devices support processorbased or stand-alone operation and interface 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 CS61574A has a receiver jitter attenuator optimized for minimum delay in switching and transmission applications, while the CS61575 attenuator is op...
