Product Information

The Si552 dual-frequency VCXO utilizes Silicon Laboratories’ advanced DSPLL® circuitry to provide a very low jitter clock for all output frequencies. The Si552 is available with any-rate output frequency from 10 to 945 MHz and selected frequencies to 1400 MHz. Unlike traditional VCXOs, where a different crystal is required for each output frequency, the Si552 uses one fixed crystal frequency 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 Si552 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 the long lead times associated with custom oscillators.

Applications:
• SONET/SDH
• xDSL
• 10 GbE LAN/WAN
• Low-jitter clock generation
• Optical modules
• Clock and data recovery
