Skyworks Solutions Inc. SKY62101 Clock Generator
Skyworks Solutions Inc. SKY62101 Clock Generator combines 5th generation DSPLL® and MultiSynth™ technologies with an ultra-low jitter VCO. The SKY62101 generator supports flexible input-to-output frequency mapping and enables single-IC clock tree designs for demanding applications. Specifications include a low jitter rating down to <55fs, up to 3.2GHz frequencies, 12 outputs, and a 56-QFN package with 8mm x 8mm dimensions. Free-run and synchronous operation is supported by the SKY62101 locking to an external crystal or oscillator. This generator is quickly and easily configured by using the Skyworks ClockBuilder® Pro (CBPro) software. Applications suitable for the SKY62101 clock generator include networking, data centers, and industrial.
