Si534
QUAD FREQUENCY CRYSTAL OSCILLATOR (XO)
(10 MHZ TO 1.4 GHZ)
Features
Applications
Description
The Si534 quad frequency XO utilizes Silicon Laboratories’ advanced
DSPLL circuitry to provide a low jitter clock at high frequencies. The Si534
is available with any-rate output frequency from 10 to 945 MHz and select
frequencies to 1400 MHz. Unlike a traditional XO where a different crystal is
required for each output frequency, the Si534 uses one fixed crystal to
provide a wide range of output frequencies. This IC based approach allows
the crystal resonator to provide exceptional frequency stability and reliability.
In addition, DSPLL clock synthesis provides superior supply noise rejection,
simplifying the task of generating low jitter clocks in noisy environments
typically found in communication systems. The Si534 IC-based XO is factory
configurable 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.
