P1P8160A
Low Jitter Clock Generator
and Peak EMI Reduction IC
Product Description
P1P8160A is a versatile low jitter clock generator and spread
spectrum frequency modulator designed to reduce electromagnetic
interference (EMI) at the clock source, allowing system wide
reduction of EMI of down stream clock and data dependent signals.
The device 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.
P1P8160A modulates the output of a 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’.
P1P8160A accepts an input from either a 27 MHz fundamental
Crystal or from an external reference clock and generates a 100 MHz
Spread Spectrum clock. The device also features a 27MHz reference
clock output. Two Trilevel logic pins, SS1% and SS2% enables
selecting one of the eight different frequency deviations along with
SSOFF. Refer to Frequency Deviation Selection table. P1P8160A
operates over a supply voltage range of 3.3 V
± 10%. P1P8160A is
available in a 10 Pin WDFN (3 mm x 3 mm) package, over
temperature range 10
°C to +85°C.
