PI6C2405A
Zero-Delay Clock Buffer
Features
• Maximum rated frequency: 133 MHz
• Low cycle-to-cycle jitter
• Input to output delay, less than 300ps
• Internal feedback allows outputs to be synchronized
to the clock input
• 5V tolerant input*
• Spread spectrum clock ready
• Operates at 3.3V VDD
• Packaging (Pb-free & Green available):
-8-pin, 150-mil SOIC (W)
-8-pin, 173-mil TSSOP (L)
Description
The PI6C2405A is a PLL based, zero-delay buffer, with the ability
to distribute five 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.
An internal feedback on OUT0 is used to synchronize the out-
puts to the input; the relationship between loading of this signal
and the outputs determines the input-output delay. PI6C2405A
is able to track spread spectrum clocking for EMI reduction.
PI6C2405A is characterized for both commercial and industrial
operation.
PI6C2405A-1H is a high-drive version of PI6C2405A-1
* CLKIN must reference the same voltage thresholds for the PLL to
deliver zero delay skewing
