Diodes Incorporated PI6CG330440 19-Output Clock Generator

Diodes Incorporated PI6CG330440 19-Output Clock Generator with a very low jitter clock generator that meets PCIe 1.0/2.0/3.0/4.0/5.0 clock requirements. This clock generator takes a reference input to generate 25MHz and 100MHz outputs. The device operates at 3.3V of supply voltage and supports Intel's CK440Q specification. This clock generator features an on-chip termination that can save 80 external resistors and simplify the layout.
