Description

The PI6CBE33125 is a low-power PCIe® 1.0/2.0/3.0/ 4.0/5.0/6.0 clock buffer. It takes a reference input to fanout twelve 100MHz low-power differential HCSL outputs with on-chip terminations for 85Ω output impedance. It supports both zero-delay and fanout buffer functions for various applications. An individual OE pin for each output provides easier power management. It uses Diodes proprietary PLL design to achieve very-low jitter that meets PCIe 1.0/2.0/3.0/4.0/5.0/6.0 requirements. Other than PCIe 100MHz support, this device also supports 133.33MHz via a pin.
