PIN CONFIGURATION

DESCRIPTION

The PL602-XX is the smallest, high performance, lowest power differential output clock IC available for HCSL

timing applications. PL602-XX offers -130dBc at 10kHz offset at 100MHz, with a very low jitter

(2 ps TIE RMS), making it ideal for HCSL applications requiring small size and low power.
