Diodes Incorporated PI6CB332016A 16-Output Fanout Clock Buffer

Diodes Incorporated PI6CB332016A 16-Output Low-Power Fanout Clock Buffer is designed as a low-power PCIe^® 5.0/6.0 solution. The device utilizes a reference input to fanout 16 low-power differential HCSL outputs up to 400MHz, with on-chip terminations for 85Ω output impedance.

The Diodes PI6CB332016A Clock Buffer supplies an individual OE pin for each output, allowing for easier power management. Furthermore, the device supports Power Down Tolerant (PDT), automatic output clock parking upon loss of input clock, and flexible startup sequencing features.
