General Description
The CS62180A and CS62180B are monolithic CMOS devices which encode and decode T1 framing formats. The devices support bit-seven and B8ZS zero suppression, and bit-robbed signaling. Clear channel mode can be selected on a per channel basis.
The serial interface has been enhanced to allow the CS62180A and CS62180B to share a chip select signal and register address space with the CS61535A, CS61574A, and CS61575 Line Interface Units.
