Overview
The LFTCXO075797 is a temperature-compensated crystal oscillator (TCXO) manufactured by IQD Frequency Products. It operates at a nominal frequency of 20 MHz with a clipped sine wave output format. The device requires a 3.3 V supply voltage and features a frequency stability of 0.28 ppm. It is housed in a compact 4-SMD, no-lead package with dimensions of 3.2 mm x 2.5 mm, belonging to the IQXT-220-1 series.
Feature Summary
- Temperature compensation ensures high frequency stability across operating conditions
- Clipped sine wave output format suitable for specific clocking requirements
- Compact surface-mount design facilitates integration into space-constrained PCB layouts
Applications
- Precision timing circuits requiring stable clock references
- Communication systems utilizing 20 MHz reference frequencies
- Industrial instrumentation demanding low drift performance
Procurement Notes
Verify the exact frequency stability specification of 0.28 ppm against the latest official datasheet before procurement. Confirm that the clipped sine wave output matches the input requirements of the downstream circuitry. Ensure the 3.3 V supply voltage aligns with the system power architecture. Check package compatibility for the 4-SMD no-lead footprint during assembly planning.
Selection Notes
Select this component when a 20 MHz TCXO with high stability is required. The 0.28 ppm stability offers superior performance compared to standard crystals. The clipped sine wave output may require level shifting or buffering depending on the load. Consider the 3.3 V supply constraint and the small 3.2x2.5 mm package size for layout optimization.
Part Context
This part belongs to the IQXT-220-1 series from IQD Frequency Products. It is designed as a surface-mount TCXO providing enhanced frequency stability over basic quartz crystals. The product line targets applications needing reliable clock sources in compact electronic devices.
Replacement Considerations
Consult official substitution lists for equivalent 20 MHz TCXOs with similar stability and package dimensions. Verify pinout and electrical characteristics match before replacing.
