PI6CG33402CZHIEX-13R

Clock Generators, PLLs, Frequency Synthesizers Overview

The PI6CG33402CZHIEX-13R is a four-output very-low power PCIe clock generator manufactured by Diodes Incorporated. It accepts a 25MHz crystal or CMOS reference input to generate four 100MHz low-power differential HCSL outputs with on-chip termination. The device operates at a nominal 3.3V supply voltage, drawing typical currents of 22mA for analog and 16mA for digital sections. It supports selectable spread spectrum options of 0%, -0.25%, or -0.5% and features programmable slew rates and output amplitudes via SMBus configuration.
