PI6CB33602
Very Low Power 6-Output PCIe Clock Buffer With On-Chip Termination
Features
Description
yy3.3V supply voltage
e PI6CB33602 is a 6-output very low power PCIe Gen1/Gen2/
yyHCSL input: 100MHz, also support 50MHz, 125MHz or Gen3/Gen4/Gen5 clock buffer. It takes a reference input to fanout
133.33MHz via SMBus
six 100MHz low power differential HCSL outputs with on-chip
yy6differentiallowpowerHCSLoutputswithon-chiptermination terminations. e on-chip termination can save 24 external re-

sistors and make layout easier. Individual OE pin for each output
provides easier power management.
OUT
yySpread spectrum tolerant
yyIndividual output enable
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
Ethernet application with 50MHz, 125MHz and 133.33MHz via
SMBus. It provides various options such as different slew rate and
amplitude through SMBUS so that users can configure the de-
vice easily to get the optimized performance for their individual
boards.
