CS62180B
T1 Framer
Features
• Monolithic T1 Framing Device
• CS62180B Supports SF(D4®), T1DM,
ESF and SLC-96® Framing Formats
• CS62180B Contains Updated AIS and
Carrier Loss Detection Criteria
• CS62180B is Pin Compatible with
DS2180A, and DS2180
General Description
The CS62180B is a monolithic CMOS device
which encodes and decodes T1 framing formats.
The device supports bit-seven and B8ZS zero suppres-
sion, and bit-robbed signaling. Clear channel mode can
be selected on a per channel basis.
The serial interface has been enhanced to allow
the CS62180B to share a chip select signal and
register address space with the CS61535A,
CS61574A, and CS61575 Line Interface Units.
Applications
• T1 Line Cards
• ISDN Primary Rate Line Cards
