ZL81000GGG2

Drivers, Receivers, Transceivers Overview

The ZL81000GGG2 is a dual BITS transceiver and composite clock receiver designed for carrier-class telecommunications equipment. It integrates two independent multi-protocol transceivers supporting DS1, E1, 2048kHz, and 6312kHz timing signals with SSM insertion and extraction capabilities. The device includes two composite clock receivers compliant with Telcordia GR-378 standards and two programmable-frequency inputs. It operates from a single 12.8MHz local oscillator and features an 8-bit parallel or SPI serial processor interface. The component functions at 1.8V with 3.3V I/O (5V tolerant) and is housed in a 256-pin CSBGA package.

Drivers, Receivers, Transceivers Procurement Notes

Verify the manufacturer designation as Microsemi Corporation within official documentation, noting that Microchip Technology acquired Microsemi. Confirm the specific ordering suffix GGG2 corresponds to the 256-pin CSBGA package and industrial temperature range (-40°C to +85°C). Ensure compatibility with the required 1.8V core voltage and 3.3V I/O levels before integration.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designing systems requiring direct reception and transmission of DS1, E1, and CC timing signals without external framer chips. Consider the integrated jitter attenuation and high-impedance receive inputs for redundant timing architectures. Verify that the 256-pin BGA footprint and thermal requirements fit the target PCB layout constraints.
