• Manufacturer Part Number: CS61304A
• Description: T1-E1 Line Interface Unit for CPE-ISDN PRI
• Manufacturer: Cirrus Logic, Inc.

Interfacing The CS61304A 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
CS61304A is used in Extended Hardware Mode,
the RCLK output does not have to be inverted be-
fore being input to the CS62180B.
