Overview
The RNA5031A-20M is a Temperature Compensated Crystal Oscillator (TCXO) manufactured by NDK. It operates at a nominal frequency of 20 MHz with CMOS output logic levels. The device requires a 3.3V supply voltage and draws a maximum current of 6 mA. Frequency stability is specified at ±4.6 ppm. It features a 10-SMD, No Lead package with dimensions of 5.00mm x 3.20mm x 1.90mm. The operational temperature range extends from -40°C to +85°C.
Feature Summary
- Integrated temperature compensation for stable frequency performance across wide operating ranges
- CMOS output interface compatible with standard digital logic circuits
- Compact surface-mount design suitable for space-constrained applications
Applications
- Portable consumer electronics requiring precise timing references
- Communication modules needing stable clock signals
- Industrial control systems operating in variable thermal environments
Procurement Notes
Verify the specific ordering suffixes provided by distributors to ensure correct packaging options such as tape and reel or cut tape are selected. Confirm that the requested part matches the exact 10-SMD no-lead package specification. Check manufacturer datasheets for any recent updates to electrical characteristics or recommended soldering profiles before integration into production designs.
Selection Notes
Select this component when a 20 MHz TCXO with CMOS outputs is required. Ensure the system power supply aligns with the 3.3V requirement. Verify that the ±4.6 ppm stability meets the application's jitter and phase noise constraints. Consider the 10-SMD footprint compatibility during PCB layout planning.
Part Context
This oscillator belongs to the NT5032BA series from NDK, designed for high-reliability timing applications. It utilizes artificial crystal technology known for superior quality and consistency. The series supports various frequencies and packages within the same family structure.
Replacement Considerations
Direct substitutes may include other 20 MHz TCXOs in 10-SMD packages with similar stability and voltage requirements. Cross-reference pinouts and electrical parameters carefully. Consult manufacturer cross-reference guides for verified equivalent parts.
