LFTCXO085775

Overview

The LFTCXO085775 is a Temperature Compensated Crystal Oscillator (TCXO) manufactured by IQD Frequency Products. It operates at a nominal frequency of 20 MHz with an HCMOS output format. The device supports a supply voltage range from 3.135 V to 3.465 V, typically centered at 3.3 V. It features a frequency stability of +/- 0.28 ppm and is designed for surface mount installation in a compact SMD package. The component functions within an extended temperature range, supporting minimum operating temperatures of -40°C and maximum operating temperatures up to +105°C.

Feature Summary

• Integrated temperature compensation circuitry ensures high frequency stability across wide thermal variations
• HCMOS digital output interface provides direct compatibility with standard logic circuits
• Compact surface-mount construction facilitates automated PCB assembly and space-constrained designs

Applications

• Telecommunications base station synchronization
• Industrial control system timing references
• Automotive electronics requiring extended temperature reliability

Procurement Notes

Verify the specific order code against the manufacturer's current catalog to confirm pinout configuration and tolerance grades. Ensure that the selected variant matches the required supply voltage and frequency stability specifications for the target application environment. Cross-reference RoHS compliance status with regional regulatory requirements prior to final procurement authorization.

Selection Notes

Select this component when precise frequency accuracy is critical over varying ambient temperatures. The HCMOS output simplifies interfacing with microcontrollers and digital processors without additional level shifting. Evaluate the thermal profile of the end-use environment to ensure the -40°C to +105°C rating covers operational extremes. Consider power consumption constraints relative to the 3.3V supply requirement.

Part Context

This TCXO belongs to IQD Frequency Products' portfolio of precision timing solutions. It utilizes quartz crystal technology enhanced with analog compensation to maintain stability. The product line targets applications demanding reliable clock signals in harsh environments, distinguishing it from basic crystal oscillators through its active temperature correction capabilities.

Replacement Considerations

Direct substitutes include other 20 MHz TCXOs with HCMOS outputs and similar stability ratings. Verify pin-to-pin compatibility and supply voltage ranges before swapping. Alternative models may offer different package sizes or aging rates; ensure electrical parameters align with the original design specifications.
