PCS3P25811 and PCS3P25812 and PCS3P25814

Spread Spectrum Clock

Generator

Features

Generates a 1x (PCS3P25811), 2x (PCS3P25812)

savings by reducing the number of circuit board layers,

ferrite beads, shielding, and other passive components

that are traditionally required to pass EMI regulations.

and 4x(PCS3P25814) low EMI spread spectrum

clock of the input frequency

The PCS3P25811/12/14 can generate an EMI reduced

clock from crystal, ceramic resonator, or system clock.

Provides up to 15dB of EMI suppression

Input Frequency: 4MHz - 32MHz

Output Frequency:

The PCS3P25811/12/14 modulate the output of a single

PLL in order to “spread” the bandwidth of a synthesized

cock, and more importantly, decreases the peak

amplitudes of its harmonics. This results in significantly

lower system EMI compared to the typical narrow band

signal produced by oscillators and most frequency

generators. Lowering EMI by increasing a signal‟s

bandwidth is called „spread spectrum clock generation.‟

PCS3P25811: 4MHz - 32MHz

PCS3P25812: 8MHz - 64MHz

PCS3P25814: 16MHz - 128MHz

Selectable spread options: Down Spread and Center

Spread

Low Power Dissipation:

3.3V: 20mW (typ) @ 6MHz

The PCS3P25811/12/14 use the most efficient and

optimized modulation profile approved by the FCC and is

implemented in a proprietary all-digital method.

3.3V: 24mW (typ) @ 12MHz

3.3V: 30mW (typ) @ 24MHz

Low inherent Cycle-to-Cycle Jitter

Supply Voltage: 2.8V to 3.6V

The PCS3P25811/12/14 have 2 pins S0 and S1 to control

the selection of Center Spread, Down Spread and No-

Spread functions. Additionally there is a 3 level logic

contol FSEL, for selecting one of the three different

frequency ranges within the operating frequency range.

Refer Input/Output Frequency Range Selection Table.

LVCMOS Input and output

Functional and Pinout compatible to Cypress

CY25811, CY25812 and CY25814

Commercial and Industrial temperature range

8-pin SOIC, TSSOP and TDFN, COL(2X2) Packages

The PCS3P25811/12/14 operate from a 2.8V to 3.6V

supply and are available in 8 pin SOIC, TSSOP and

TDFN, COL(2X2) packages, over Commercial and

Industrial temperature range.

Product Description

The PCS3P25811/12/14 devices are versatile spread

spectrum frequency modulators designed specifically for

a wide range of input clock frequencies from 4MHz to

32MHz.

Applications

The PCS3P25811/12/14 are targeted towards EMI

management in applications such as LCD Panels, MFPs,

Digital copiers, Networking, PC peripheral devices,

consumer electronics, and embedded controller systems.

The

PCS3P25811/12/14

reduce

electromagnetic

interference (EMI) at the clock source, allowing system

wide reduction of EMI of down stream clock and data

dependent signals. It allows significant system cost
