Product details

PLL clock synthesis with spread-spectrum EMI control

The Infineon W181-01GI is a clock/frequency synthesizer with an integrated PLL and spread-spectrum clock generation, packaged in an 8-SOIC footprint. It accepts either a clock or crystal input and delivers a single CMOS output at up to 75 MHz.

Supply flexibility and temperature grade

With a 1:1 input-to-output ratio and no differential signalling on either side, this part is designed for single-ended clock distribution in low-complexity timing trees.

Frequently asked questions

What is the W181-01GI's PLL status and what does it mean for my design?

The W181-01GI includes an integrated PLL (phase-locked loop) for frequency synthesis. This means it can multiply a lower-frequency reference (clock or crystal) up to the 75 MHz output maximum, enabling a single crystal to feed multiple clock domains.

What is the closest pin-compatible alternative to the W181-01GI?

No pin-compatible alternative is listed in the available records. The part is a standalone clock generator in the 8-SOIC footprint; functional replacements would require board-level evaluation of the PLL, spread-spectrum profile, and supply range.
