Features
•Maximum rated frequency: 133 MHz
•Low cycle-to-cycle jitter
•Input to output delay, less than 200ps
•External feedback pin allows outputs to be synchronized
to the clock input
•5V tolerant input*
•Operates at 3.3V VDD
•Test mode allows bypass of the PLL for system testing
purposes (e.g., IBIS measurements)
•Space-saving Packaging (Pb-free and Green Available):
— 8-pin, 150-mil SOIC (W)
Description
The PI6C2404A-1 is a PLL-based, zero-delay buffer, with the ability
to distribute four outputs of up to 133 MHz at 3.3V. Two banks of
two outputs exist, OUTA[1–2] and OUTB[1–2].
An external feedback pin is used to synchronize the outputs to the
input; the relationship between loading of this signal and the other
outputs determines the input-output delay.
The PI6C2404A-1 is characterized for both commercial and industrial
operation.

PI6C2404A-1
Zero-Delay Clock Buffer
The relationship between loading of the FB_IN signal and other outputs determines the input-output delay. Zero delay is achieved when
all outputs, including feedback, are loaded equally.
