This document introduces two clock chips AD9516 and AD9549 from Analog Devices. AD9516 is a low phase noise clock generator with integrated 14-channel clock distribution at jitter levels below 500 fs, while AD9549 is a two input clock generator with extended holdover functionality. It has a programmable loop filter to clean jitter from input clocks and features flexible output frequency options.
This document introduces Analog Devices' timing innovations, specifically the AD9516 and AD9549 integrated circuits. The AD9516 is a 14-channel clock generator with an integrated VCO designed to increase performance and reliability while cutting system clock costs.
