P2040A  
LCD Panel EMI Reduction IC  
Features  
implemented in a proprietary all digital method.  
ꢀ
ꢀ
ꢀ
FCC approved method of EMI attenuation.  
The P2040A 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’.  
Provides up to 20dB of EMI suppression.  
Generates a low EMI spread spectrum clock of the  
input frequency.  
ꢀ
ꢀ
Input frequency range: 30MHz to 110MHz.  
Optimized for VGA, SVGA, and higher resolution  
XGA LCD Panels.  
ꢀ
Internal loop filter minimizes external components  
and board space.  
ꢀ
ꢀ
ꢀ
Six selectable high spread ranges up to ± 2%.  
Two selectable modulation rates.  
SSON# control pin for spread spectrum enable  
and disable options.  
Applications  
The P2040A is targeted towards digital flat panel  
applications for notebook PCs, palm-size PCs, office  
automation equipments and LCD monitors.  
ꢀ
ꢀ
ꢀ
ꢀ
ꢀ
ꢀ
Low cycle-to-cycle jitter.  
Wide operating range.  
16mA output drives.  
TTL or CMOS compatible outputs.  
Low power CMOS design.  
Supports most mobile graphic accelerator  
specifications.  
ꢀ
Products available for automotive temperature  
range. (Refer Spread Spectrum Range Selection  
Tables)  
ꢀ
Available in 8-pin SOIC and TSSOP.  
Product Description  
The P2040A is a versatile spread spectrum frequency  
modulator designed specifically for digital flat panel  
applications. The P2040A reduces electromagnetic  
interference (EMI) at the clock source, allowing system  
wide reduction of EMI of down stream clock and data  
dependent signals. The P2040A allows significant system  
cost savings by reducing the number of circuit board  
layers ferrite beads,  
shielding and other passive  
components that are traditionally required to pass EMI  
regulations.  
The P2040A uses the most efficient and optimized  
modulation profile approved by the FCC and is
