• 1 Selectable 48, 30 or 12MHz USB Clock output.
• Selectable Spread Spectrum (SST) for EMI reduction
on CPU clock.
• PowerPC compatible CPU Clock.
• Advanced, low power, sub-micron CMOS processes.

• 3.3V and/or 2.5V operation.
Available in 16-Pin 150mil SOP.
DESCRIPTION
The PLL702-06 is a low cost, low jitter, and high
performance clock synthesizer for generic Printer
applications. It provides one CPU clock and a selectable
48, 30 or 12MHz (USB) output. The user can choose
among 9 different clock frequencies and 3-selectable down-
spread Spread Spectrum modulation to reduce EMI on
CPU clock. All frequencies are generated from a single low
cost 14.31818MHz crystal. CPU clock can be driven from
an independent 2.5V or 3.3V power supply.
