CY25200

Programmable Spread Spectrum

Clock Generator for EMI Reduction

Features

Benefits

■ Wide operating output (SSCLK) frequency range

❐ 3–200 MHz

■ Suitable for most PC peripherals, networking, and consumer

applications.

■ Provides wide range of spread percentages for maximum EMI

reduction to meet regulatory agency Electro Magnetic

Compliance (EMC) requirements. Reduces development and

manufacturing costs and time to market.

■ Programmable spread spectrum with nominal 31.5 kHz

modulation frequency

■ Center spread: ±0.25% to ±2.5%

■ Down spread: –0.5% to –5.0%

■ Eliminates the need for expensive and difficult to use higher

order crystals.

■ Input frequency range

❐ External crystal: 8–30 MHz fundamental crystals

❐ External reference: 8–166 MHz clock

■ Internal PLL generates up to 200 MHz outputs; also generates

custom frequencies from an external crystal or a driven source.

■ Integrated phase-locked loop (PLL)

■ Programmable crystal load capacitor tuning array

■ Low cycle-to-cycle jitter

■ Enables fine tuning of output clock frequency by adjusting

C_Loadof the crystal. Eliminates the need for external C_Load

capacitors.

■ Application compatibility in standard and low power systems.

■ 3.3V operation with 2.5V output clock drive option

■ Spread spectrum On and Off function

■ Power down or Output Enable function

■ Output frequency select option

■ Provides ability to enable or disable spread spectrum with an

external pin.

■ Enables low power state or output clocks to High-Z state.

■ Enables quick generation of sample prototype quantities.

■ Field-programmable

■ Package: 16 pin TSSOP
