SKY62101 - Ultra-Low Jitter Clock Generator
SKY62101
12-Output, Any-Frequency, Any-Output Clock Generator with Ultra-Low Jitter
Description
The SKY62101 clock generator combines Fifth-generation DSPLL® and MultiSynth™ technologies with an ultra-low jitter VCO to deliver ultra-low jitter (<55 fs) in PCIe Gen 1/2/3/4/5/6/7 compliant high-performance applications. The device is used in applications like 112G/224G SerDes, coherent optics, and data center equipment that demand the highest level of integration and jitter performance. All PLL components are integrated on-chip, eliminating the risk of noise coupling associated with discrete solutions. The SKY62101 supports free-run and synchronous operation by locking to an external crystal or oscillator. The SKY62101 is quickly and easily configured using Skyworks ClockBuilder® Pro (CBPro) software. ClockBuilder Pro assigns a custom part number for each unique configuration. Devices ordered with custom part numbers are factory-programmed, making it easy to get a custom clock configuration uniquely tailored for each application. Custom part numbers that are factory-programmed will power up with a known frequency configuration. The device may also be user-configured at power-up or internally configured in non-volatile memory (NVM) using the CBPro Field Programmer via the serial interface.
