LFTVXO079052

Overview

The LFTVXO079052 is a Voltage Controlled Temperature Compensated Crystal Oscillator (VCTCXO) manufactured by IQD Frequency Products. It operates at a nominal frequency of 20 MHz with a frequency stability of ±0.5 ppm. The device requires a single 1.8 V supply voltage and draws a maximum current of 1.5 mA. It features a clipped sine wave output format and utilizes a 4-SMD, no-lead package measuring 2.00 mm x 1.60 mm x 0.80 mm. The component supports an operating temperature range from -30°C to +85°C.

Feature Summary

• Integrated temperature compensation for high frequency stability
• Low power consumption suitable for battery-operated systems
• Compact surface-mount footprint for space-constrained designs

Applications

• Mobile communication devices
• Wireless sensor networks
• Portable electronic equipment

Procurement Notes

Verify the specific ordering suffix to confirm packaging configuration, such as Reel or Cut Tape, as these affect handling procedures. Ensure the supply voltage matches the 1.8 V requirement strictly. Confirm RoHS compliance status if environmental regulations apply to the assembly process. Cross-reference the manufacturer part number with distributor codes to avoid selection errors during procurement.

Selection Notes

Select this component when a balance between low power usage and high frequency stability is required in compact applications. The 1.8 V supply makes it suitable for modern low-voltage digital logic families. Consider the clipped sine wave output compatibility with downstream circuitry. Evaluate the thermal performance within the specified -30°C to +85°C range against the operational environment.

Part Context

This oscillator belongs to the IQXT-205-2-18 series, designed for applications demanding precise timing in small form factors. IQD Frequency Products specializes in quartz-based timing solutions, providing components that integrate crystal resonators with compensation circuits. This series targets the mobile and consumer electronics markets where size and power efficiency are critical design constraints.

Replacement Considerations

Direct substitutes must match the 20 MHz frequency, 1.8 V supply, and 4-SMD package dimensions. Verify that alternative VCTCXOs offer comparable ±0.5 ppm stability and clipped sine wave outputs. Check pinout compatibility and thermal characteristics before integration.
