General Description

ZL81000 provides two DS1/E1/2048kHz transceivers (transmitters plus receivers) specifically designed for BITS/SSU timing in carrier-class telecommunications equipment.

Each transceiver provides full support for DS1, E1 and G.703 2048kHz synchronization signals in and out and includes SSM message insertion and extraction.

The device also includes two composite clock (CC) receivers and two general-purpose CMOS clock inputs to provide additional support as needed for legacy interfaces.

Key Features
