• Input to output delay, less than 200ps
• Internal feedback allows outputs to be synchronized
to the clock input
• Operates at 3.3V V
• Space-saving Packages:
150-mil SOIC (W)
173-mil TSSOP (L)

Functional Description
The PI6C2409 is a PLL based, zero-delay buffer, with the ability
to distribute nine outputs of up to 133MHz at 3.3V.
All the outputs are distributed from a single clock input CLKIN and
output OUT0 performs zero delay by connecting a feedback to PLL.
PI6C2409 has two banks of four outputs that can be controlled by
the selection inputs, SEL1 & SEL2. It also has a powersparing feature:
when input SEL1 is 0 and SEL2 is 1, PLL is turned off and all
outputs are referenced from CLKIN. PI6C2409 is available in
high drive and industrial environment versions.
An internal feedback on OUT0 is used to synchronize the
outputs to the input; the relationship between loading of this signal
and the outputs determines the input-output delay.
PI6C2409 are characterized for both commercial and
industrial operation

Output Load Difference: OUT0 Load - OUTx Load (pF)
The relationship between loading of the OUT0 signal and other outputs determines the input-output delay. Zero delay is achieved when
all outputs, including feedback, are loaded equally.
