Overview
The QTT252-19.200MCS-T is a Voltage Controlled Temperature Compensated Crystal Oscillator (VCTCXO) manufactured by QST Products, LLC. It operates at a nominal frequency of 19.2 MHz and utilizes a crystal base resonator. The device supports a supply voltage of 3.3V and features a clipped sine wave output format. It is housed in a compact SMD2520-4P package with no lead construction. The component is designed for operation within a temperature range of -30°C to +85°C.
Feature Summary
- Integrates voltage control and temperature compensation for stable frequency generation
- Utilizes a quartz crystal base resonator for high precision oscillation
- Features a compact surface-mount design suitable for space-constrained applications
Applications
- Wireless communication modules requiring stable clock sources
- Portable electronic devices needing low-power oscillators
- Industrial control systems operating in variable thermal environments
Procurement Notes
Verify the specific suffix codes against official QST documentation to ensure correct electrical characteristics and packaging options. Confirm that the requested variant matches the required output waveform and supply voltage specifications for your circuit design before placing orders.
Selection Notes
Select this component when a VCTCXO solution is required for 19.2 MHz applications. Ensure the system design accommodates the 3.3V supply requirement and the SMD2520-4P footprint. Consider the operational temperature range limits during the initial hardware planning phase.
Part Context
This oscillator belongs to the QTT252 series of VCTCXOs from QST. The series offers various frequency options and packaging configurations. This specific model provides a standard 19.2 MHz output, commonly used in telecommunications and data interface standards.
Replacement Considerations
Direct substitutes include other QST VCTCXOs with identical pinouts and electrical parameters. Cross-reference with TCXO models from other manufacturers only if form factor and performance specs align perfectly.
