Shown here is a comparison of Skyworks Solutions Si53x XO and a SAW Oscillator. The Si530/531 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. Why is the Si53x oscillator superior to a SAW oscillator? Wider frequency range, >50x better frequency tolerance, and more output formats and voltage thresholds. Additional Si53x features include: Any frequency I2C configurable options, On chip power regulation provides better PSRR, no ferrite bead inductor or external LDO is required, and short lead times.
