Skyworks Solutions Si530/531 Crystal Oscillator (XO)
Product Overview
The Skyworks Solutions Si530/531 Crystal Oscillator (XO) leverages advanced DSPLL circuitry to deliver low-jitter clock signals across a wide frequency range, from 10 MHz to 1.4 GHz. Unlike traditional XOs that require a dedicated crystal for each frequency, the Si530/531 utilizes a single fixed crystal, enabling flexible any-rate output frequencies from 10 to 945 MHz and select frequencies up to 1400 MHz. This IC-based design ensures exceptional frequency stability and reliability, while the DSPLL clock synthesis offers superior supply noise rejection, making it ideal for generating low-jitter clocks in noisy communication system environments. The Si530/531 is factory configurable for user-specific requirements, including frequency, supply voltage, output format, and temperature stability, eliminating long lead times for custom oscillators.
