LFPTXO000068

Overview

The IQD Frequency Products LFPTXO000068 is a Temperature Compensated Crystal Oscillator (TCXO) operating at a nominal frequency of 20 MHz. It utilizes HCMOS output format with a maximum supply voltage of 3.3 V and a typical current consumption of 6 mA. The device features a ±320 ppb frequency stability over an extended operating temperature range of -5°C to +80°C. It is housed in a compact 10-SMD surface-mount package measuring 7.00 mm x 5.00 mm with a maximum height of 2.25 mm.

Feature Summary

• Integrated temperature compensation circuitry for high frequency stability across the operating range
• HCMOS output interface compatible with standard digital logic circuits
• Built-in enable/disable functionality for power management control

Applications

• Mobile communication devices requiring low power clock sources
• Portable electronic equipment with strict size constraints
• Industrial control systems needing stable timing references

Procurement Notes

Verify the specific order suffix and lifecycle status, as this component may be classified under factory special order or limited availability. Confirm RoHS compliance and lead time requirements directly with authorized distributors before finalizing procurement plans.

Selection Notes

Select this TCXO when a 20 MHz reference with ±320 ppb stability is required within a 7x5mm footprint. Ensure the application environment stays within the -5°C to +80°C operational window and that the 3.3V HCMOS output aligns with the target system's logic levels.

Part Context

This part belongs to the E3179LF series of surface-mount TCXOs from IQD Frequency Products. These oscillators are designed for applications demanding precise timing in space-constrained environments, utilizing quartz crystal technology enhanced by internal compensation circuits.

Replacement Considerations

Cross-reference with other 20 MHz HCMOS TCXOs in 10-SMD packages. Verify pinout compatibility and electrical specifications such as supply voltage and load capacitance before substituting.
