Analog Devices introduced a fully-programmable, jitter-attenuating, dual-clock translator IC for optical transport network (OTN) applications and high-density line cards. The AD9559 quad-input multiservice line card adaptive clock translator simultaneously supports different standard frequencies for wired communications applications, including synchronous Ethernet, SONET/SDH, 1/10/100G Ethernet, Fiber Channel, and other applications that require low jitter, flexibility and fast time-to-market.
The AD9559 translator IC synchronously converts any standard input frequency to any standard output frequency at up to 1.25 GHz with sub-400-fs RMS (root mean square) total jitter over a 12-kHz to 20-MHz integration bandwidth. The AD9559 replaces two synchronous timing devices with a single IC, helping designers with board space constraints and cost optimization.
