• Manufacturer Part Number: CS61574A
• Description: T1/E1 LINE INTERFACE
• Manufacturer: Cirrus Logic, Inc.

Interfacing The CS61575 and CS61574A With
the CS62180B T1 Transceiver
To interface with the CS62180B, connect the de-
vices as shown in Figure A4. In this case, the line
interface and CS62180B are in Host Mode con-
trolled by a microprocessor serial interface. If the
line interface is used in Hardware Mode, then the
line interface RCLK output must be inverted be-
fore being input to the CS62180B. If the
CS61575 or CS61574A is used in Extended
Hardware Mode, the RCLK output does not have
to be inverted before being input to the
CS62180B.
