Overview
Description
The 5P83908 is a high-performance, 1-to-8 crystal input to LVCMOS fanout buffer with Output Enable pins. This device accepts a fundamental mode crystal from 10MHz to 40MHz and outputs LVCMOS clocks with best-in-class phase noise performance.
The 5P83908 features a synchronous glitch-free output enable function to eliminate any intermediate incorrect output clock cycles when enabling or disabling outputs. It comes in standard TSSOP packages or small QFN packages and can operate from 1.8V to 3.3V supplies.
