Low Noise Fractional PLL in TSMC 65nm LP
This PLL has been designed for use with high performance A/D converters, where low jitter clock generation is critical to the success of applications such as DVB, Cable Modem and Wireless LAN.
A Fractional N type PLL is used yielding excellent phase noise performance with good frequency resolution flexibility.
The PLL is designed to provide excellent jitter performance while also maintaining low current consumption. It uses a third order loop filter which gives very good spurious performance, supply rejection, phase noise and jitter performance.
