3QHM572C2.0-16.384

Oscillators Overview

The 3QHM572C2.0-16.384 is a spread-spectrum crystal oscillator (SSXO) manufactured by Mercury United Electronics, Inc. It operates at a nominal frequency of 16.384 MHz and utilizes CMOS output logic levels. The device is housed in a compact 4-SMD, no-lead package, specifically identified as the SMD7050-4P form factor. Designed for low electromagnetic interference (EMI) applications, it features a 3.3V enable/disable control function to manage power consumption. The component is RoHS compliant and lead-free, ensuring adherence to environmental standards for electronic assemblies.

Oscillators Feature Summary

• Spread-spectrum modulation capability for reduced EMI emissions
• CMOS output interface compatible with standard digital logic
• Active enable/disable control via 3.3V signal for power management
• Compact surface-mount packaging suitable for space-constrained designs

Oscillators Applications

• High-speed FPGA timing reference circuits
• Data handling systems requiring precise clock synchronization
• Embedded controllers needing low-EMI clock sources

Oscillators Procurement Notes

Verify the manufacturer designation carefully, as official documentation lists Mercury United Electronics, Inc. rather than Mercury Electronics Ind. Co. Ltd. Confirm the specific frequency suffix matches project requirements. Ensure the 3.3V enable pin configuration aligns with system voltage levels. Check RoHS compliance status if required by regional regulations. Validate the SMD7050-4P footprint against PCB design constraints before ordering.

Oscillators Selection Notes

Select this component when low EMI is critical for signal integrity in high-speed digital environments. The CMOS output simplifies interfacing with standard logic families without additional level shifting. The enable feature allows for dynamic power management during idle states. Consider the operating temperature range and load capacitance requirements relative to the target application's stability needs.

Oscillators Part Context

This part belongs to the 3QHM572 series of spread-spectrum oscillators from Mercury United Electronics. Similar variants include frequencies such as 14.318 MHz and 16.5888 MHz within the same package family. The series is designed to replace standard fixed-frequency crystals where EMI reduction is prioritized over absolute frequency stability.

Oscillators Replacement Considerations

Direct substitutes within the same series include 3QHM572C2.0-14.318 and 3QHM572C2.0-16.5888, provided the frequency difference is acceptable. Cross-referencing with other SSXO manufacturers requires verification of pinout compatibility and output drive strength.
