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
