Product Description  
Features  
ƒ
ƒ
ƒ
FCC approved method of EMI attenuation.  
The P2040C is a selectable spread spectrum frequency  
modulator designed specifically for digital flat panel  
applications. The P2040C reduces electromagnetic  
interference (EMI) at the clock source which provides  
system wide reduction of EMI of all clock dependent  
signals. The P2040C allows significant system cost  
savings by reducing the number of circuit board layers  
and shielding that are traditionally required to pass EMI  
regulations.  
Provides up to 15 dB of EMI suppression  
Generates a low EMI spread spectrum clock of the  
input frequency  
50 MHz to 170 MHz input frequency range  
Optimized for 54MHz, 65MHz, 81MHz, 140MHz,  
and 162MHz pixel clock frequencies  
Internal loop filter minimizes external components  
and board space

8 selectable spread ranges, up to +/- 2.2%  
SSON# control pin for spread spectrum enable  
and disable options  
The P2040C uses the most efficient and optimized  
modulation profile approved by the FCC and is  
implemented in a proprietary all-digital method.

2 selectable modulation rates  
Low cycle-to-cycle jitter  
3.3V operating voltage  
16 mA output drives  
TTL or CMOS compatible outputs  
Ultra low power CMOS design  
Supports most mobile graphic accelerator and  
LCD timing controller specifications  
Available in 8 pin SOIC and TSSOP  
The P2040C modulates the output of a single PLL in  
order to “spread” the bandwidth of a synthesized clock  
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”.  
ƒ
Applications  
The P2040C is targeted towards digital flat panel  
applications for Notebook PCs, Palm-size PCs,  
Office Automation Equipments, and LCD Monitors.
