ZL30142GGG2 General Description

The ZL30142GGG2 from Microchip Technology Inc. is a powerful frequency translator and clock generator IC that caters to the diverse clocking needs of networking and telecommunications applications. With its three independent frequency translation channels, this IC can efficiently translate input clock signals to new output frequencies, ranging from 1 kHz to 710 MHz. Not only does it provide versatile clock distribution capabilities, but it also offers frequency synthesis and jitter attenuation functions to ensure the delivery of high-quality clock signals to downstream components. Its flexible configuration options, accessible via a serial interface, make it easy for users to program the device according to specific clocking requirements. Additionally, the ZL30142GGG2 comes equipped with advanced clocking features such as programmable phase adjustment, clock distribution, and redundancy switching, which collectively contribute to improved system reliability

Key Features
