515BAA155M520BAGR

Oscillators Overview

The Skyworks Solutions Inc. 515BAA155M520BAGR is a single-frequency Voltage-Controlled Crystal Oscillator (VCXO) from the Si515 series. It operates within a frequency range of 100 kHz to 250 MHz, with a specific configuration for 155.52 MHz. The device utilizes an LVDS output format and functions on a 3.3 V supply voltage, drawing a maximum current of 26 mA. It supports a load capacitance of 15 pF and features an enable/disable pin. The component is housed in a 5 mm x 3.2 mm SMD package with a height of 1.33 mm, designed for operation between -40°C and +85°C.

Oscillators Feature Summary

• Voltage-controlled crystal oscillator architecture allowing frequency tuning via control voltage
• LVDS differential output format for high-speed signal integrity
• Integrated enable/disable functionality for power management
• Surface-mount design compatible with automated assembly processes

Oscillators Applications

• Telecommunications equipment requiring precise clock generation
• Data communication interfaces needing low-jitter timing sources
• Test and measurement instruments utilizing stable reference frequencies
• Networking hardware components operating at standard baud rates

Oscillators Procurement Notes

Verify the complete part number including the AGR suffix to confirm reel packaging and specific frequency tolerance. Ensure the application circuit supports LVDS signaling requirements and provides the necessary control voltage range for VCXO operation. Confirm that the 3.3 V supply rail meets the minimum voltage specifications under all operating conditions. Check for RoHS compliance documentation if required by project standards.

Oscillators Selection Notes

Select this component when a tunable clock source is required rather than a fixed-frequency oscillator. The LVDS output is suitable for applications demanding noise immunity over longer trace lengths. Consider the 15 pF load capacitance requirement when designing the external circuit. Evaluate the 26 mA current consumption against system power budgets. Verify that the 5x3.2 mm footprint fits within the available PCB area constraints.

Oscillators Part Context

This VCXO belongs to the Si515 family of oscillators, which are designed for general-purpose applications requiring frequency agility. Unlike standard XO models such as the 511BBA155M520AAG, this variant allows for frequency adjustment. The AGR suffix indicates tape-and-reel packaging, distinguishing it from cut-tape variants. It shares the same physical dimensions as other Si515 devices but differs in electrical characteristics due to its voltage-control capability.

Oscillators Replacement Considerations

Direct replacements must match the Si515 series, 155.52 MHz frequency, LVDS output, and 5x3.2 mm package. Models like 515BAA155M520BAG differ only in packaging format. Other Skyworks VCXOs may require retuning or circuit modification if their control voltage ranges or current consumption profiles differ significantly.
