Overview
The LFTCXO085779 is a temperature-compensated crystal oscillator (TCXO) manufactured by IQD Frequency Products. It operates at a nominal frequency of 38.88 MHz with an HCMOS output format. The device provides high frequency stability of ±100 ppb and functions within an extended temperature range from -40°C to +105°C. Powered by a 3.3V supply, it utilizes surface-mount technology for integration into compact electronic designs.
Feature Summary
- Temperature compensation ensures stable frequency performance across wide thermal variations
- HCMOS digital output interface compatible with standard logic circuits
- Extended operating temperature range suitable for demanding industrial environments
Applications
- Industrial control systems requiring precise timing under variable temperatures
- Telecommunications infrastructure equipment
- Automotive electronics applications
Procurement Notes
Verify the specific ordering suffix against the manufacturer's current catalog to confirm pinout configuration, tolerance levels, and packaging options. Ensure the selected variant matches the required supply voltage and load capacitance specifications for the target application circuit design.
Selection Notes
Select this component when high frequency stability is critical in thermally challenging conditions. The HCMOS output simplifies interfacing with microcontrollers and digital logic. Consider the ±100 ppb stability requirement against system jitter budgets before finalizing the design choice.
Part Context
This TCXO belongs to IQD Frequency Products' portfolio of precision timing solutions. It complements their broader range of quartz crystals and oscillators designed for global markets including aerospace, automotive, and medical sectors. The product supports designs requiring reliable clock signals in harsh operational environments.
Replacement Considerations
Consult official substitution guides for equivalent TCXOs with matching 38.88 MHz frequency and HCMOS outputs. Verify that alternative components meet the same ±100 ppb stability and -40°C to +105°C temperature range requirements.
