Description

The DIODES PI6CB332000 is an 20-output very low-power PCIe

clock buffer. It is capable of distributing the reference clocks for

UPI,SAS,SATA,andotherapplicationsaswell.Ittakesanreference

input to fanout 20 100MHz low-power differential HCSL outputs

with on-chip 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 Gen 1/Gen 2/Gen 3/Gen 4/Gen 5/Gen 6 requirement.

Notes:

1. No purposely added lead. Fully EU Directive 2002/95/EC (RoHS), 2011/65/EU (RoHS 2) & 2015/863/EU (RoHS 3) compliant.

2. See https://www.diodes.com/quality/lead-free/ for more information about Diodes Incorporated’s definitions of Halogen- and Antimony-free, "Green" and Lead-free.

3. Halogen- and Antimony-free "Green” products are defined as those which contain <900ppm bromine, <900ppm chlorine (<1500ppm total Br + Cl) and <1000ppm

antimony compounds.
