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
