Product Overview
The Skyworks Solutions Si545 Ultra Series Crystal Oscillator is an advanced, any-frequency clock generator utilizing 4th generation DSPLL technology. It delivers ultra-low jitter and low phase noise across its operating range of 0.2 to 1500 MHz with <1 ppb resolution. The Si545 offers exceptional reliability, frequency stability, and aging performance. Its on-chip power supply filtering provides superior power supply noise rejection, simplifying clock generation in noisy systems. The device is factory-programmed to custom frequencies, enabling rapid sample delivery within 1-2 weeks. It supports various user-defined specifications including frequency, output format, and OE pin configuration. The Si545 is designed for applications such as 100G/200G/400G OTN, optical Ethernet, broadcast video, datacenters, test and measurement, clock and data recovery, and FPGA/ASIC clocking.
