FEATURES
Full swing CMOS outputs with 25 mA drive
capability at TTL levels.
Reference 20-30MHz crystal or clock.
Integrated crystal load capacitor: no external
load capacitor required.
Output clocks up to 150MHz at 3.3V.
Low phase noise (-126dBc/Hz @ 1kHz).
Output Enable function.
Low jitter (RMS): 6.4ps (period), 9.4ps (accum.)
Advanced low power sub-micron CMOS process.
3.3V operation.
Available in 8-Pin SOIC or TSSOP.
DESCRIPTIONS
The PLL601-15 is a low cost, high performance and
low phase noise clock synthesizer. It implements
PhaseLink's proprietary analog and digital Phase
Locked Loop techniques for a fixed 5x multiplier.
The chip accepts crystal or clock inputs ranging from
20 to 30MHz, and produces outputs clocks up to
150MHz at 3.3V.
