New Product Introduction

Renesas 8V79S680

The 8V79S680 is a fully integrated, clock and SYSREF signal fanout buffer for JESD204B applications

The 8V79S680 is a fully integrated, clock and SYSREF signal fanout buffer for JESD204B applications. The main function of the device is the distribution and fanout of high-frequency clocks and low-frequency system reference signals generated by a JESB204B clock generator, extending its fanout capabilities and providing additional phase-delay. It can deliver very low phase noise clocks and precise, phase-adjustable SYSREF synchronization signals as required in GSM, WCDMA, LTE, LTE-A radio board implementations.
