P1707A  
Notebook LCD Panel EMI Reduction IC  
Features  
the clock source, allowing system wide reduction of EMI of  
down stream clock and data dependent signals. The  
P1707A 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.  
FCC approved method of EMI attenuation.  
Generates a low EMI spread spectrum clock of the  
input frequency.  
Optimized for frequency range from 60MHz to  
175MHz.  
Internal loop filter minimizes external components  
and board space.  
The P1707A 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’.  
Four selectable spread ranges.  
Low inherent Cycle-to-cycle jitter.  
3.3V Operating Voltage.  
Ultra-low power CMOS design.  
14.85 mA @3.3V, 140MHz  
16.69 mA @3.3V, 162MHz  
17.78 mA @3.3V, 175MHz  
Supports notebook VGA and other LCD timing  
controller applications.  
Pinout compatible to ICS MK1707 and Cypress  
CY25561/CY25560.  
SSON/SBM pin for Spread Spectrum On/Off and  
Standby Mode controls.  
Available in 8-pin SOIC and TSSOP Packages.  
The P1707A uses the most efficient and optimized  
modulation profile approved by the FCC and is  
implemented in a proprietary all digital method.  
Applications  
The P1707A is targeted towards notebook LCD displays,  
and other displays using an LVDS interface, PC peripheral  
devices, and embedded systems.  
Product Description  
The P1707A is a versatile spread spectrum frequency  
modulator designed specifically for input clock frequencies.  
The P1707A reduces electromagnetic interference (EMI) at  
VDD
