512ACA000270AAG

Overview

The Skyworks Solutions Inc. 512ACA000270AAG is a pin-configurable standard crystal oscillator (XO) from the Si512 series, designed for high-performance clocking applications. It operates at a nominal frequency of 148.351648 MHz with an alternative output option of 148.5 MHz. The device utilizes LVPECL output format and requires a supply voltage ranging from 2.97 V to 3.63 V, typically operating at 3.3 V. It features a maximum current consumption of 26 mA and supports enable/disable functionality. The component is housed in a compact 6-SMD, no-lead package measuring 7.00 mm x 5.00 mm x 1.80 mm, suitable for surface mount assembly.

Feature Summary

• Pin-configurable architecture allows flexible integration into various system designs without custom mask changes.
• LVPECL output format provides differential signaling for improved noise immunity and signal integrity.
• Supports dual frequency outputs including 148.351648 MHz and 148.5 MHz options within the same package.
• Integrated enable/disable control function reduces power consumption during inactive periods.

Applications

• High-speed data communication interfaces requiring precise clock synchronization
• Telecommunications equipment utilizing 148.5 MHz reference frequencies
• Digital signal processing systems demanding low jitter performance
• Network infrastructure components requiring reliable differential clock sources

Procurement Notes

Verify the specific frequency requirement between 148.351648 MHz and 148.5 MHz before ordering, as these represent distinct operational configurations within the same part family. Confirm that the target application circuitry supports LVPECL logic levels and termination requirements. Ensure the PCB footprint matches the 7x5 mm SMD package dimensions and thermal specifications. Cross-reference the manufacturer's latest datasheet for any updates on pin configuration options or electrical characteristics relevant to the specific order quantity and delivery timeline.

Selection Notes

Select this component when a stable, low-jitter clock source is required for high-speed digital systems. The LVPECL output is preferred over CMOS for longer trace lengths and noisy environments due to its superior noise margin. Consider the Si512 series for applications needing pin-configurability to reduce inventory complexity. Evaluate the 26 mA current draw against system power budgets. Verify compatibility with the host controller's input thresholds and termination resistors to ensure signal integrity and proper operation across the specified temperature range.

Part Context

The 512ACA000270AAG belongs to Skyworks' Si512 family of pin-configurable oscillators, which offer design flexibility by allowing customers to select specific frequencies and features through pin strapping. This series is engineered for telecommunications and networking applications where reliability and precision are critical. Unlike fixed-frequency oscillators, the configurable nature allows for customized solutions without the lead time associated with fully custom parts, balancing performance needs with supply chain efficiency.

Replacement Considerations

Direct replacements must match the Si512 series specifications, including LVPECL output and 7x5 mm package. Verify equivalent frequency stability and phase noise characteristics. Check if alternative SKUs within the 512ACAxx series offer the required 148.351648 MHz or 148.5 MHz output. Ensure that any substitute maintains the same enable/disable functionality and supply voltage range to guarantee seamless integration into existing designs.
