Description

The DIODES PI6CBE33063 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 six 100MHz low-power differential HCSL outputs with on-chip terminations for 33Ω 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.
