Interfacing The CS61577 With the CS62180B
T1 Transceiver
To interface with the CS62180B, connect the de-
vices as shown in Figure A5. 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
CS61577 is used in Extended Hardware Mode,
the RCLK output does not have to be inverted be-
fore being input to the CS62180B.
