SKY63104/05/06 - Jitter Attenuating Clocks
SKY63104,SKY63105,SKY63106
12-Output, Any-Frequency, Any-Output Jitter Attenuators/Clock Multipliers with Ultra-Low Jitter
Description
SKY63104/05/06 Jitter Attenuators combine 5th-generation DSPLL® and MultiSynth™ technologies with an ultra-low jitter VCO to deliver ultra-low jitter (<55 fs) for high-performance applications like 112G and 224G SerDes and Coherent Optics. They are designed for applications demanding the highest levels of integration and jitter performance. All PLL components are integrated on-chip, eliminating the risk of noise coupling associated with discrete solutions. The SKY63104 has a single DSPLL with two MultiSynths; the SKY63105 has two DSPLLs with one MultiSynth, and the SKY63106 has three DSPLLs. All devices support free-run, synchronous, and holdover modes as well as enhanced hitless switching minimizing the phase transients associated when switching between input clocks. These devices are available with either non-volatile memory (NVM), to enable powering up with a known frequency configuration, or with an external flash option. Programming the SKY63104/05/06 is easy with Skyworks’ ClockBuilder® Pro (CBPro) software. The devices can be factory-programmed, allowing them to power up to known frequencies and settings, or shipped as “blank” devices to provide more flexibility.
