LFTCXO085771

Overview

The LFTCXO085771 is a temperature-compensated crystal oscillator (TCXO) manufactured by IQD Frequency Products. It operates at a nominal frequency of 10 MHz with an output format of HCMOS. The device provides high frequency stability of +/- 0.28 ppm and is housed in a surface-mount package measuring 7 mm x 5 mm. It functions within a supply voltage range of 3.135 V to 3.465 V, typically rated for 3.3 V operation. The component supports an extended industrial operating temperature range from -40°C to +105°C.

Feature Summary

• Temperature compensation ensures stable frequency performance across wide thermal variations
• HCMOS output interface compatible with standard digital logic circuits
• High precision frequency stability minimizes timing errors in sensitive applications

Applications

• Industrial communication systems requiring precise clock synchronization
• Automotive electronics operating in extreme temperature environments
• Test and measurement equipment demanding low phase noise and stability

Procurement Notes

Verify the specific order code against the manufacturer's current catalog to ensure availability of the exact 10 MHz variant. Confirm that the HCMOS output level matches the target system's voltage requirements. Check RoHS compliance status if restricted substances are a concern for the assembly process. Ensure the 7x5mm footprint aligns with the PCB layout constraints.

Selection Notes

Select this component when a 10 MHz reference signal with sub-ppm stability is required. The wide temperature range makes it suitable for harsh environments where standard oscillators may drift. Consider the HCMOS output compatibility with downstream logic gates. Evaluate power consumption relative to the 3.3V supply rail to ensure efficient system design.

Part Context

This part belongs to the LFTCXO series of surface-mount TCXOs from IQD Frequency Products. These devices utilize advanced compensation techniques to maintain accuracy over temperature. The series offers various frequencies and packages, positioning this model as a solution for mid-range precision timing needs in compact form factors.

Replacement Considerations

Direct substitutes include other 10 MHz TCXOs with similar HCMOS outputs and stability ratings. Verify pinout compatibility and physical dimensions before swapping. Cross-reference specifications for aging rates and phase noise to ensure equivalent performance in the final application.
