7Q-20.000MBG-T

Oscillators Overview

The 7Q-20.000MBG-T is a Temperature Compensated Crystal Oscillator (TCXO) manufactured by TXC Corporation, operating at a nominal frequency of 20 MHz. It utilizes a quartz resonator housed in a compact 4-SMD, No Lead package measuring 5.00 mm x 3.20 mm with a maximum height of 1.40 mm. The device supports a supply voltage range from 1.8 V to 3.3 V and delivers a clipped sine wave output. Frequency stability is rated at ±0.5 ppm over the industrial temperature range of -40°C to +85°C. Initial frequency tolerance is ±1.0 ppm at 25°C. The component features low current consumption and is designed for surface-mount assembly.

Oscillators Feature Summary

• Provides high-frequency stability of ±0.5 ppm across the full industrial temperature range.
• Operates on a wide single-supply voltage range from 1.8V to 3.3V.
• Delivers a clipped sine wave output signal suitable for sensitive RF applications.
• Utilizes a compact 4-SMD no-lead package for efficient board space utilization.

Oscillators Applications

• GPS navigation systems requiring precise timing references
• Wireless communication modules needing stable carrier frequencies
• Portable electronic devices demanding low power consumption
• Test and measurement equipment requiring high accuracy

Oscillators Procurement Notes

This component is classified as End-of-Life (EOL) and is no longer manufactured by TXC Corporation. Procurement should focus on verifying the authenticity of remaining stock from authorized distributors or surplus suppliers. Engineers must confirm that the source documents explicitly identify the part as genuine TXC product before acquisition. Due to the discontinued status, long-term availability cannot be guaranteed, and replacement planning is strongly recommended for new designs.

Oscillators Selection Notes

Select this component only if the specific 20 MHz TCXO specification with ±0.5 ppm stability matches the system requirements. Verify that the clipped sine wave output format is compatible with the receiving circuit input impedance. Ensure the operating environment falls within the -40°C to +85°C range. Since the part is obsolete, evaluate alternative solutions immediately to ensure supply chain continuity for future production runs.

Oscillators Part Context

The 7Q series represents TXC Corporation's line of precision TCXOs designed for applications requiring superior frequency stability compared to standard XO oscillators. This specific model belongs to the 7Q-GPS sub-family, optimized for global positioning systems. The 4-SMD package allows for automated surface-mount placement, supporting high-volume manufacturing processes while maintaining small form factor constraints typical in modern mobile and embedded electronics.

Oscillators Replacement Considerations

As an EOL product, direct substitutes are unavailable from the original manufacturer. Consider evaluating other TXC TCXO models with similar pinouts and specifications, such as the 7Q-20.000MDG-T, if datasheet compatibility is confirmed. Cross-reference with competitors offering 20 MHz TCXOs in 5.0x3.2mm packages to ensure mechanical and electrical interchangeability.
