PI6C2308A

3.3V Zero-Delay Buffer

ProductFeatures

FunctionalDescription

• 10 MHz to 140 MHz operating range

• Zero input-output propagation delay, adjustable by

capacitive load on FBK input

• Multipleconfigurations, seeAvailablePI6C2308A

Configurations table

Providingtwobanksof fouroutputs,thePI6C2308Aisa 3.3Vzero-

delay buffer designed to distribute clock signals in applications

includingPC,workstation,datacom,telecom,andhigh-performance

systems. Each bank of four outputs can be controlled by the select

inputs as shown in the Select Input Decoding Table.

The PI6C2308A provides 8 copies of a clock signal that has 150ps

phase error compared to a reference clock. The skew between the

output clock signals for PI6C2308Ais less than 200ps. When there

table shows additional examples when the PLL shuts down. The

PI6C2308A configuration table shows all available devices.

• Input to output delay, less than 150ps

• Multiple low skew outputs

- Output-output skew less than 200ps

- Device-device skew less than 500ps

- Two banks of four outputs, Hi-Z by two select inputs

• Low Jitter, less than 200ps

• 3.3Voperation

The base part, PI6C2308A-1, provides output clocks in sync with

areferenceclock. Withfasterriseandfalltimes,thePI6C2308A-1H

isthehigh-driveversionofthePI6C2308A-1.Dependingonwhich

output drives the feedback pin, PI6C2308A-2 provides 2X and 1X

clocksignalsoneachoutputbank.ThePI6C2308A-3allowstheuser

to obtain 4X and 2X frequencies on the outputs. The PI6C2308A-4

provides 2X clock signals on all outputs. PI6C2308A (-1, -2, -3, -4)
