Product 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 outputs 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
