Product details

Spread-spectrum clock generator — what it does for your EMI budget

The Cypress CY25402SXC is a spread-spectrum clock generator with an integrated PLL. It accepts an LVCMOS or crystal reference input and delivers three clock outputs at up to 166 MHz.

Package and footprint — 8-SOIC, field-swappable

That is a standard, widely stocked footprint — easy to hand-solder, easy to probe, and straightforward to swap in the field if a unit goes down. No fine-pitch or BGA rework needed; a basic iron and a steady hand get it done.

Lifecycle — active, no near-term obsolescence concern

The official product status is Active. For a production BOM, this means you are not forced into a redesign or a lifetime-buy calculation right now.
