CA 95134
408-943-2600
Revised September 8, 2003
Features
Fully integrated phase-locked loop (PLL)
FailSafe output
PLL driven by a crystal oscillator that is phase-aligned
with external reference
Two 6.312-MHz outputs from 8-kHz input
Low-jitter, high-accuracy outputs
3.3V ± 5% operation
16-lead TSSOP
Benefits
Integrated high-performance PLL tailored for telecommuni-
cations frequency synthesis eliminates the need for external
loop filter components
When reference is off, DCXO maintains clock outputs and
SAFE pin indicates FailSafe conditions
DCXO maintains continuous operation should the input
reference clock fail
Glitch-free transition simplifies system design
Works with commonly available, low-cost 18.432-MHz
crystal
Zero-ppm error for all output frequencies
Compatible across industry standard design platforms
Industry standard package with 6.4 × 5.0 mm
2
footprint and
a height profile of just 1.1 mm
