511BBA000149AAG

Oscillators Overview

The Skyworks Solutions Inc. 511BBA000149AAG is a standard clock oscillator from the Si511 series, operating at a fixed frequency of 74.175824 MHz. It utilizes an LVDS output format and features a single enable pin (OE P1). The device operates within a supply voltage range of 2.97 V to 3.63 V, with a typical working voltage of 3.3 V. It is housed in a compact 6-SMD, No Lead package measuring 5 mm x 3.2 mm x 1.28 mm. The unit supports a load capacitance of 15 pF and maintains a frequency stability of 25 ppm across an industrial temperature range of -40°C to +85°C.

Oscillators Feature Summary

• Generates a precise 74.175824 MHz clock signal using LVDS differential outputs for high-speed data transmission integrity.
• Incorporates a dedicated enable pin (Pin 1) to control power consumption by switching between active operation and low-power standby states.

Oscillators Applications

• High-speed serial communication interfaces requiring stable clock sources
• Data acquisition systems needing precise timing synchronization
• Telecommunications equipment utilizing LVDS signaling standards

Oscillators Procurement Notes

Verify the specific frequency tolerance and phase jitter specifications against the official Skyworks datasheet before integration. Confirm that the LVDS output impedance matches the target PCB trace requirements. Ensure the design accommodates the 5x3.2 mm surface mount footprint and the 3.3V supply rail constraints defined in the electrical characteristics.

Oscillators Selection Notes

Select this component when a fixed 74.175824 MHz frequency is required with LVDS output capabilities. The Si511 series offers a balance of performance and size suitable for space-constrained designs. Consider the 25 ppm stability requirement and the -40°C to +85°C operating range to ensure compatibility with the environmental conditions of the final application.

Oscillators Part Context

This part belongs to the Skyworks Si511 family of standard clock oscillators. These devices are designed to provide low-jitter, high-frequency clock signals for digital circuits. The 511BBA variant specifically denotes a single-frequency XO with an enable function, distinguishing it from programmable or multi-output alternatives within the broader oscillator portfolio.

Oscillators Replacement Considerations

Direct substitutes include other Skyworks Si511 models with identical 74.175824 MHz frequencies and LVDS outputs, such as the 511BBA000149BAGR if reel packaging is preferred over cut tape. Cross-manufacturer replacements require matching LVDS output levels, frequency accuracy, and physical dimensions.
