LFTVXO075810

Overview

The LFTVXO075810 is a Voltage-Controlled Temperature Compensated Crystal Oscillator (VCTCXO) manufactured by IQD Frequency Products. It operates at a nominal frequency of 38.88 MHz with a clipped sine wave output format. The device is powered by a 3.3V supply and features a compact surface-mount package measuring 3.20mm x 2.50mm with a maximum seated height of 1.00mm. This component belongs to the TCVCXO product category designed for precision timing applications requiring voltage control capabilities.

Feature Summary

• Integrates temperature compensation circuitry to maintain frequency stability across operating conditions
• Provides voltage-controlled tuning capability for precise frequency adjustment
• Delivers clipped sine wave output signal suitable for RF and communication interfaces
• Utilizes a low-profile surface-mount package for automated PCB assembly

Applications

• Wireless communication systems requiring stable clock references
• RF transceiver modules needing frequency agility
• Industrial equipment with precision timing requirements
• Automotive electronics compliant with strict environmental standards

Procurement Notes

Verify the specific output waveform configuration, as clipped sine wave outputs differ from digital logic levels. Confirm that the receiving circuitry supports the amplitude and impedance characteristics of this analog-style output. Ensure the design accounts for the voltage control pin requirements if dynamic frequency adjustment is necessary. Cross-reference the mechanical dimensions against the PCB footprint to guarantee proper soldering and alignment during assembly processes.

Selection Notes

Select this oscillator when a balance between high stability and voltage tunability is required within a small form factor. The 3.3V supply voltage aligns with standard digital logic levels, simplifying power distribution. Consider the clipped sine wave output when interfacing with mixers or RF stages rather than digital inputs. Evaluate the thermal management needs given the compact 3.20mm x 2.50mm package size and its impact on long-term frequency drift in enclosed environments.

Part Context

This component is part of IQD's extensive portfolio of frequency control products, which includes crystals, oscillators, and resonators. IQD Frequency Products, now part of the Wurth Group, leverages decades of expertise in quartz technology. The LFTVXO series represents their advanced VCTCXO offerings, targeting markets that demand reliable performance in challenging environments such as automotive and industrial sectors.

Replacement Considerations

LFTVXO076348 is a similar VCTCXO in the same 6-SMD package family but operates at 40 MHz with different electrical specifications. Direct substitution requires verifying frequency compatibility and output interface requirements. Other models in the IQXT-316-6 series may offer alternative frequencies but must be evaluated for pin-out and parameter alignment.
