LFTCXO085777

Overview

The LFTCXO085777 is a Temperature Compensated Crystal Oscillator (TCXO) manufactured by IQD Frequency Products. It operates at a nominal frequency of 20 MHz with high stability of +/- 0.28 ppm. The device features an HCMOS output interface and requires a 3.3V supply voltage. It is housed in a compact 4-SMD, No Lead surface mount package, designed for reliable performance in space-constrained electronic applications requiring precise timing signals.

Feature Summary

• Provides high-frequency stability of +/- 0.28 ppm for precision timing
• Features HCMOS output compatibility for digital logic integration
• Utilizes a compact 4-SMD no-lead surface mount package design

Applications

• Precision communication systems requiring stable clock sources
• Test and measurement equipment needing accurate timebases
• Industrial control systems with strict timing requirements

Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against your system design before procurement. Confirm that the 3.3V supply voltage aligns with your power architecture. Ensure the 4-SMD footprint matches your PCB layout constraints. Check for RoHS compliance status if required by your manufacturing standards. Validate input signal levels to ensure proper HCMOS interface operation.

Selection Notes

Select this component when high stability around 0.28 ppm is critical for system performance. Consider the 20 MHz nominal frequency for specific clocking needs. Evaluate the 3.3V supply requirement against available power rails. Assess the physical size of the 4-SMD package for board space limitations. Compare HCMOS output drive capabilities with downstream circuit inputs.
