Product Information

Back to top
The Si540 Ultra Series™ oscillator utilizes Silicon Laboratories’ advanced 4th generation DSPLL® technology to provide an ultra-low jitter, low phase noise clock at any output frequency. The device is factory-programmed to any frequency from 0.2 to 1500 MHz with <1 ppb resolution and maintains exceptionally low jitter for both integer and fractional frequencies across its operating range. The Si540 offers excellent reliability and frequency stability as well as guaranteed aging performance. On-chip power supply filtering provides industry-leading power supply noise rejection, simplifying the task of generating low jitter clocks in noisy systems that use switched-mode power supplies.

Offered in industry-standard 3.2×5 mm and 5×7 mm footprints, the Si540 has a dramatically simplified supply chain that enables Silicon Labs to ship custom frequency samples 1-2 weeks after receipt of order. Unlike a traditional XO, where a different crystal is required for each output frequency, the Si540 uses one simple crystal and a DSPLL IC-based approach to provide the desired output frequency. This process also guarantees 100% electrical testing of every device. The Si540 is factory-configurable for a wide variety of user specifications, including frequency, output format, and OE pin location/polarity. Specific configurations are factory-programmed at time of shipment, eliminating the long lead times associated with custom oscillators.

Applications:
• 100G/200G/400G OTN, coherent optics
• 10G/40G/100G optical ethernet
• 3G-SDI/12G-SDI/24G-SDI broadcast video
• Servers, switches, storage, NICs, search acceleration
• Test and measurement
• Clock and data recovery
• FPGA/ASIC clocking
