Functional 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 (CL) of the crystal, eliminating the
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 2.5 V.
Programmability enables fast prototyping, which is particularly
useful when doing EMC testing and determining the optimal
spread settings.
