Si530/531
CRYS TAL OSCILLATOR (XO) (10 MHZ TO 1.4 GHZ)
Features
Applications
Description
The Si530/531 XO utilizes Skyworks Solutions’ advanced DSPLL
®
circuitry
to provide a low jitter clock at high frequencies. The Si530/531 is available
with any-rate output freque nc y fro m 10 to 945 MHz and select freque nc ies to
1400 MHz. Unlike a traditional XO, where a different crystal is required for
each output frequency, the Si530/531 uses one fixed crystal to provide a
wide range of output frequencies. This IC based approach allows the crystal
resonator to p rov ide e xception al freq uenc y sta bility and reliability. In additio n,
DSPLL clock synthesis provides superior supply noise rejection, simplifying
the task of generating low jitter clocks in noisy environme nts typically found in
communicatio n systems. The Si530/531 IC bas ed XO is factor y conf igurable
for a wide variety of user specifications including frequency, supply voltage,
output format, and temperature stability. Specific configurations are factory
programmed at time of shipment, thereby eliminating long lead times
associated with custom oscillators.
