SI516 - DUAL FREQUENCY VOLTAGE-CONTROLLED CRYSTAL OSCILLATOR (VCXO)

📥 Download Datasheet

General Description

 Broadcast video  Telecom  Switches/routers  FPGA/ASIC clock generation The Si516 dual frequency VCXO utilizes Silicon Laboratories' advanced PLL technology to provide any frequency from 100 kHz to 250 MHz.

Unlike a traditional VCXO where a different crystal is required for each output frequency, the Si516 uses one fixed crystal and Silicon Labs’ proprietary synthesizer to generate any frequency across this range.

This IC-based approach allows the crystal resonator to provide enhanced reliability, improved mechanical robustness, and excellent stability.
