PI6CB33201
Very-Low-Power Two-Output PCIe Clock Buffer With On-Chip Termination
Features
Description
e PI6CB33201 is a two-output very-low-power PCIe Gen1/
yy3.3V Supply Voltage
Gen2/Gen3/Gen4/Gen5 clock buffer. It takes a reference input to
fanout two 100MHz low-power differential HCSL outputs with
on-chip terminations. e on-chip termination can save eight
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/Gen5 requirements.
Other than PCIe 100MHz support, this device also support Eth-
ernet application with 50MHz, 125MHz, and 133.33MHz via
SMBus. It provides various options such as different slew rate
and amplitude through SMBUS, so users can configure the de-
vice easily to get the optimized performance for their individual
boards.
