Description

The PI6CB332016A is a low-power PCIe® 5.0/6.0 clock buffer. It

takes a reference input to fanout 16 low-power differential HCSL

outputs up to 400MHz, with on-chip terminations for 85Ω out-

put impedance. An individual OE pin for each output provides

easier power management. The device also supports Power Down

Tolerant (PDT), automatic output clock parking upon loss of in-

put clock, and Flexible Startup Sequencing features.

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.
