Programmable Spread Spectrum

Description

The CY25200 is a programmable clock generator with spread

spectrum capability. Spread spectrum modulates the output

clock frequency over a small range, spreading the energy and

reducing the energy peak. This is a powerful technique to reduce

EMI in a variety of applications.

It uses either an external reference clock or a crystal for an input.

It also uses a PLL to generate a spread spectrum output clock

that can be a different frequency than the input. Up to six output

clocks are available and up to two of them can be REFCLKs

(copies of the input clock, without spread).

The CY25200 is highly configurable. Programmable variables

include the input and output frequencies, spread percentage,

center spread or down spread, and control pin functions. The

oscillator pin capacitance can also be programmed to match the

load capacitance requirement (C

need for external capacitors.

Available features include Output Enable, Power Down, Spread

On/Off, Frequency Select, and the option to power some output

clocks at 2.5V.

Cypress’ web-based CyberClocks Online software is used to

configure the device. Programmability enables fast prototyping,

which is particularly useful when doing EMC testing and deter-

mining the optimal spread settings.
