PI6CG330440AZUDIEX

Clock Generators, PLLs, Frequency Synthesizers Overview

The PI6CG330440AZUDIEX is a 19-output PCIe 5.0/6.0 clock generator manufactured by Diodes Incorporated. It supports Intel's CK440Q specification and operates on a 3.3V supply voltage. The device generates seven dedicated 100MHz outputs, three dedicated 25MHz outputs, and nine selectable multiplexable outputs capable of driving either 25MHz or 100MHz signals. It features an integrated crystal oscillator supporting 25MHz reference inputs from XO, TCXO, or OCXO sources. The component utilizes on-chip termination to eliminate external resistors and achieves PCIe 6.0 common clock RMS jitter of less than 22fs. It is housed in a 100-contact, 8x8mm UQFN (ZUD) package.
