Product Overview
The Si530/531 XO is a crystal oscillator utilizing Silicon Laboratories' advanced DSPLL circuitry to deliver low jitter clock signals at high frequencies. It offers any-rate output frequencies from 10 MHz to 945 MHz, with select frequencies up to 1.4 GHz. Unlike traditional XOs requiring multiple crystals for different frequencies, this IC-based solution uses a single fixed crystal for enhanced stability and reliability. Its DSPLL clock synthesis provides superior supply noise rejection, ideal for noisy communication system environments. The device is factory configurable for frequency, supply voltage, output format, and temperature stability, minimizing lead times for custom specifications.
