LFTVXO085764

Overview

The LFTVXO085764 is a Voltage Controlled Temperature Compensated Crystal Oscillator (VCTCXO) manufactured by IQD Frequency Products. It operates at a nominal frequency of 20 MHz with an HCMOS output format. The device requires a supply voltage ranging from 3.135 V to 3.465 V and features amplitude control functionality. It utilizes a 4-SMD, No Lead package with dimensions of 7.00 mm x 5.00 mm x 2.00 mm maximum height. The unit supports an operating temperature range from -40°C to +105°C.

Feature Summary

• Integrated amplitude control function for signal management
• Temperature compensated stability over extended industrial ranges
• Compact surface mount packaging suitable for space-constrained designs

Applications

• Wireless communication systems requiring stable clock sources
• Industrial equipment needing high-temperature reliability
• Test and measurement instrumentation

Procurement Notes

Verify the specific ordering suffix and package variant when sourcing, as manufacturer part numbers may include distinct codes for tape-and-reel or bulk configurations. Confirm that the selected revision matches the required amplitude control specifications and output drive capabilities. Ensure compatibility with the target PCB footprint and reflow soldering profiles defined in the official datasheet. Cross-reference the latest documentation to confirm RoHS compliance status and lead-free material declarations prior to procurement.

Selection Notes

Select this component when a 20 MHz reference with voltage-controlled tuning and amplitude regulation is required. The wide operating temperature range makes it suitable for harsh environments where standard oscillators might fail. Compare against fixed-frequency TCXOs if tuning flexibility is not needed. Evaluate power consumption and current draw against system budget constraints. Consider the physical size relative to available board real estate during the initial design phase.

Part Context

This oscillator belongs to the IQXT-200 series family from IQD Frequency Products. The series focuses on providing precise frequency generation with additional control features like amplitude adjustment. These components are designed to replace older through-hole solutions with modern surface-mount alternatives while maintaining high performance standards for critical timing applications.

Replacement Considerations

Direct substitutes within the same IQD series should be checked for identical pinout and electrical characteristics. Verify that any alternative model supports the same 20 MHz frequency and HCMOS output logic levels. Ensure the replacement maintains the 4-SMD no-lead form factor for mechanical compatibility.
