Pin ConfigurableSelectable Oscillators Overview

The Skyworks Solutions Inc. 513BAA000644AAGR is a dual-frequency standard crystal oscillator (XO) from the Si513 series, designed for general-purpose clocking applications. It operates within a frequency range of 0.1 MHz to 250 MHz and provides two distinct output frequencies: 161.1328 MHz and 174.7031 MHz. The device utilizes an I2C interface for configuration and features an active enable pin (OE Pin 1). It supports LVDS output format with a load capacitance of 15 pF and maintains a frequency stability of 50 PPM. Operating on a single supply voltage between 2.97 V and 3.63 V, it consumes typical current of 19 mA. The component is housed in a compact 7 mm x 5 mm surface-mount package and functions reliably across an industrial temperature range of -40°C to +85°C.

Pin ConfigurableSelectable Oscillators Procurement Notes

Verify the specific dual-frequency requirement against the datasheet specifications before ordering, as the part delivers fixed outputs of 161.1328 MHz and 174.7031 MHz. Confirm that the I2C address and enable pin logic match the system design. Ensure the PCB footprint accommodates the 7 mm x 5 mm SMD package dimensions. Check for RoHS compliance status if required by project regulations. Validate supply chain availability through authorized distributors to avoid counterfeit components.

Pin ConfigurableSelectable Oscillators Selection Notes

Select this model when a single component must provide two specific high-frequency clock options without external switching. Compare against single-frequency XOs if only one output is needed to optimize cost. Consider the LVDS output format requirements versus CMOS alternatives for noise immunity. Evaluate the 50 PPM stability against stricter jitter requirements of the target application. Ensure the 3.3 V nominal supply voltage aligns with the system power rails.

Pin ConfigurableSelectable Oscillators Part Context

This component belongs to the Skyworks Si513 family of standard oscillators, which are known for their flexibility and low phase noise. The Si513 series typically offers various output formats and packaging options to suit diverse electronic designs. As a dual-frequency variant, it simplifies bill-of-materials by replacing multiple single-frequency parts. It competes with other programmable and fixed-frequency oscillators in the market, offering a balance of performance and configurability.

Pin ConfigurableSelectable Oscillators Replacement Considerations

Direct replacements may include other Skyworks Si513 variants with matching frequencies or output formats. Cross-reference with similar dual-frequency XOs from manufacturers like Microchip or Epson if supply constraints exist. Verify that substitute parts support the same I2C interface and enable pin functionality. Ensure physical package compatibility to maintain PCB layout integrity.
