PLL-based spread spectrum clock generator in SOIC-8
The W181-03GI is a PLL-based clock/frequency synthesizer with spread spectrum modulation, delivering a CMOS output up to 75 MHz from a clock or crystal input. Spread spectrum clocking reduces peak EMI by modulating the output frequency — useful for passing radiated emissions tests in consumer and computing equipment without adding ferrites or shielding.
Supply flexibility and single-circuit timing
Single-circuit design (Number of Circuits: 1) with non-differential I/O — the input accepts a single-ended clock or crystal, and the output is a single-ended CMOS rail.
