531FA156M250DG

Oscillators Overview

The Skyworks Solutions Inc. 531FA156M250DG is a standard clock oscillator from the Si531 series, designed for single-frequency applications within the 10-1417 MHz range. It operates at a nominal frequency of 156.25 MHz with a stability of ±61.5 ppm. The device utilizes an LVDS output format and functions on a 2.5 V supply voltage, drawing up to 90 mA. It features a 6-SMD, no-lead package measuring 7 mm x 5 mm x 1.65 mm. The component supports operation between -40°C and +85°C and includes an enable/disable function via Pin 1.

Oscillators Feature Summary

• Generates a precise 156.25 MHz clock signal using a crystal resonator
• Provides differential LVDS output signals for high-speed data transmission
• Integrates an enable/disable control pin for power management flexibility

Oscillators Applications

• High-speed serial communication interfaces requiring stable clocking
• Network infrastructure equipment such as routers and switches
• Data center server backplanes and storage arrays
• Telecommunications base stations and transport networks

Oscillators Procurement Notes

Verify the specific suffix 'DG' against official Skyworks documentation to confirm lead-free status and tape-and-reel packaging specifications. Ensure the design-in process accounts for the required 2.5V supply tolerance and load capacitance matching. Confirm that the 6-SMD footprint aligns with the target PCB layout guidelines provided in the datasheet.

Oscillators Selection Notes

Select this model when a fixed 156.25 MHz frequency is required with LVDS signaling capabilities. Consider the Si531 series if low phase noise and high stability are critical for the application. Evaluate the 7x5mm package size constraints against available board space. Compare against other Skyworks oscillators if different output formats or voltage levels are needed.

Oscillators Part Context

This component belongs to the Si531 family of standard oscillators, which are widely used in digital systems for clock generation. The 531FA variant specifically denotes the LVDS output configuration and 2.5V operating voltage. It serves as a fundamental timing source for synchronous logic circuits and high-bandwidth data paths.

Oscillators Replacement Considerations

The 531FA156M250DGR is a parameter-equivalent reel version of this part. Other Skyworks models may offer similar frequencies but require verification of output format and voltage compatibility.
