QVMQF576P25-2.5B-33.333

Oscillators Overview

The QVMQF576P25-2.5B-33.333 is a Voltage-Controlled Temperature Compensated Crystal Oscillator (VCTCXO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 33.333 MHz with an LVPECL output format. The device requires a 2.5V supply voltage and features an Enable/Disable control function. Frequency stability is specified at ±2.5 ppm, while the Absolute Pull Range (APR) is ±8 ppm. The component is housed in a compact 6-SMD, No Lead package with dimensions of 7.0mm x 5.0mm x 2.5mm.

Oscillators Feature Summary

• Integrates temperature compensation for enhanced frequency stability across operating ranges
• Supports low-voltage PECL output signaling for high-speed digital interfaces
• Includes enable/disable functionality for power management control

Oscillators Applications

• Telecommunications base station synchronization
• High-speed data transmission equipment clocking
• Network infrastructure timing sources

Oscillators Procurement Notes

Verify the specific manufacturer designation, as documentation references both Mercury Electronics Ind. Co. Ltd and Mercury United Electronics, Inc. Confirm that the part number suffix corresponds to the 2.5V supply and LVPECL output configuration. Ensure compatibility with the required 33.333 MHz frequency and ±2.5 ppm stability specifications before procurement.

Oscillators Selection Notes

Select this component when a stable 33.333 MHz reference is required for LVPECL applications. The VCTCXO architecture provides superior performance compared to standard TCXOs by actively correcting frequency drift. Consider the 6-pin SMD footprint for space-constrained designs requiring precise timing without external tuning components.

Oscillators Part Context

This model belongs to the QuikXO VCTCXO series from Mercury, designed for surface-mount assembly. The QVMQF576P25 prefix indicates the specific oscillator family, while the suffix defines the electrical parameters including voltage, output type, and frequency. It serves as a precision timing source replacing discrete crystal and compensation circuits.

Oscillators Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. Verify pinout and electrical compatibility if considering alternative VCTCXO models from other manufacturers.
