LFTVXO076346

Overview

The LFTVXO076346 is a Voltage-Controlled Temperature-Compensated Crystal Oscillator (VCTCXO) from the IQXT-316-4 series by IQD Frequency Products. It operates at a nominal frequency of 25 MHz with a high frequency stability of ±0.25 ppm. The device features a clipped sine wave output format and is designed for surface mount installation in a compact 6-SMD, no-lead package measuring 7.0 mm x 5.0 mm x 2.0 mm. It functions within an operating temperature range of -5°C to +85°C and supports a supply voltage range from 500 mV to 7 V, typically utilizing 3.3 V.

Feature Summary

• Delivers exceptional frequency stability of ±0.25 ppm suitable for precision timing applications
• Generates a clipped sine wave output signal compatible with various receiver inputs
• Utilizes a compact surface-mount package design for efficient PCB space utilization

Applications

• Precision communication systems requiring stable clock references
• Test and measurement equipment demanding low phase noise
• Industrial control systems operating in extended temperature ranges

Procurement Notes

Verify the specific output load requirements and control voltage range against your system design before ordering. Confirm that the clipped sine wave output level matches the input sensitivity of the downstream component. Ensure the operating temperature range of -5°C to +85°C aligns with your environmental specifications. Check for any specific RoHS compliance documentation if required by your manufacturing standards.

Selection Notes

Select this model when high frequency stability is critical alongside a small form factor. The clipped sine wave output is ideal for driving high-impedance loads or specific receiver stages. Consider the 3.3 V nominal supply voltage compatibility with your power rails. The wide supply voltage range offers flexibility in power design, while the SMT package aids in automated assembly processes.

Part Context

This component belongs to the IQXT-316-4 series of VCTCXOs, which are engineered for applications requiring superior frequency accuracy over temperature variations. IQD Frequency Products specializes in frequency control solutions, and this series represents their commitment to miniaturization without compromising performance. The part is distinct from HCMOS output variants like the LFTVXO076345, offering an analog-style output instead.

Replacement Considerations

The LFTVXO076349CUTT is a related variant within the same product family but operates at 30.72 MHz. Direct substitution requires verifying frequency compatibility. Other models in the IQXT-316 series may share the same footprint but differ in frequency or output type. Always consult the official datasheet to confirm pinout and electrical parameter equivalence before replacing.
