511JBB-CAAG

Programmable Oscillators Overview

The Skyworks Solutions Inc. 511JBB-CAAG is a programmable crystal oscillator (XO) from the Si511 series, designed for general-purpose clocking applications. It operates at a supply voltage of 1.8V and delivers an LVDS output format with a frequency stability of ±25ppm. The device supports enable/disable functionality and is housed in a compact 6-SMD, no-lead package measuring 3.20mm x 2.50mm. It functions within a temperature range of -40°C to +85°C, drawing a maximum supply current of 23mA.

Programmable Oscillators Feature Summary

• Supports programmable frequency generation within the 0.1-250 MHz range
• Provides differential LVDS output signals for high-speed data transmission
• Includes dedicated enable/disable pin control for power management

Programmable Oscillators Applications

• High-speed serial communication interfaces requiring precise clocking
• Network infrastructure equipment such as routers and switches
• Data acquisition systems needing stable timing references

Programmable Oscillators Procurement Notes

Verify the specific programming parameters, including target frequency and load capacitance, against the application requirements before procurement. Confirm that the LVDS output compatibility matches the receiving circuitry. Ensure the 1.8V supply voltage aligns with the system power architecture. Check the package dimensions for PCB footprint compatibility. Validate the operating temperature range suitability for the intended environment.

Programmable Oscillators Selection Notes

Select this component when a low-voltage, small-footprint programmable oscillator is required. The LVDS output offers noise immunity suitable for high-frequency designs. Consider the ±25ppm stability for standard timing needs. Evaluate the 23mA current consumption against power budget constraints. Compare with other Si511 variants if different supply voltages or output formats are needed.

Programmable Oscillators Part Context

The 511JBB-CAAG belongs to the Skyworks Si511 family of single-frequency programmable oscillators. This series provides flexibility in frequency selection while maintaining a consistent form factor. It complements fixed-frequency XO options by allowing design customization without changing the physical layout. The family supports various output formats and supply voltages for diverse electronic applications.

Programmable Oscillators Replacement Considerations

Direct substitutes include other Skyworks Si511 series parts with matching LVDS outputs and 1.8V operation, such as 511JBAxxxxxCAG or 511JCAxxxxxCAG, provided the programmed frequency and package size are identical. Verify parameter equivalence for frequency stability and current consumption.
