The PI6CB332000 is an 20-output very low-power PCIe clock buffer. It takes an reference input to fanout 20 100MHz low-power differential HCSL outputs with onchip terminations. The on-chip termination can save 80 external resistors and make layout easier. 8 OE pins combined with SMBus register pins for controlling each output provides easier power management.

It uses Diodes' proprietary design to achieve very-low jitter that meets PCIe Gen1/Gen2/Gen3/Gen4/Gen5 requirement.


  • Supports Intel's DB2000Q pinout
