Description
The Si550 VCXO utilizes Silicon Laboratories’ advanced DSPLL circuitry to
provide a low-jitter clock at high frequencies. The Si550 is available with
any-rate output frequency from 10 to 945 MHz and selected frequencies to
1400 MHz. Unlike traditional VCXO’s where a different crystal is required for
each output frequency, the Si550 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 Si550 IC-based VCXO is
factory configurable for a wide variety of user specifications, including
frequency, supply voltage, output format, tuning slope, and temperature
stability. Specific configurations are factory programmed at time of shipment,
thereby eliminating long lead times associated with custom oscillators.
