Description
The PI6CB18601 is an 6-output very low power PCIe Gen1/Gen2/
Gen3/Gen4 clock buffer. It takes an reference input to fanout
eight 100MHz low power differential HCSL outputs with on-chip
terminations. The on-chip termination can save 24 external resistors
and make layout easier. Individual OE pin for each output provides
easier power management.
It uses Diodes proprietary PLL design to achieve very low jitter
that meets PCIe Gen1/Gen2/Gen3/Gen4 requirements. Other
than PCIe 100MHz support, this device also support Ethernet application
with 50MHz or 125MHz via SMBus. It provides various
options such as different slew rate and amplitude through strapping
pins or SMBUS so that users can configure the device easily
to get the optimized performance for their individual boards.
