Overview
The LFTVXO075811 is a Voltage-Controlled Temperature-Compensated Crystal Oscillator (VCTCXO) manufactured by IQD Frequency Products. It operates at a nominal frequency of 40 MHz with an HCMOS output format. The device requires a 3.3V supply voltage and draws a maximum current of 7mA. It features a frequency stability of ±280ppb over the operating temperature range. The component is housed in a compact 4-SMD, No Lead package with dimensions of 0.197" L x 0.126" W (5.00mm x 3.20mm) and a maximum height of 0.059" (1.50mm).
Feature Summary
- Integrates voltage control for precise frequency tuning within VCTCXO architecture.
- Provides clipped sine wave output suitable for low-noise applications.
- Delivers high frequency stability of ±280ppb across the specified temperature range.
Applications
- Wireless communication systems requiring stable clock sources.
- Test and measurement equipment needing precise frequency references.
- Industrial control systems utilizing surface-mount technology.
Procurement Notes
Verify the specific ordering suffix to ensure correct packaging and tolerance specifications. Confirm that the required frequency stability and supply voltage align with system design constraints. Check for RoHS compliance status if environmental regulations apply. Ensure the 4-SMD footprint matches the PCB layout guidelines provided in the official datasheet.
Selection Notes
Select this model when a 40 MHz reference with ±280ppb stability is required. Consider the 3.3V supply requirement and 7mA current draw for power budgeting. The 4-SMD package suits space-constrained designs. Evaluate the need for voltage control functionality versus fixed-frequency oscillators.
Part Context
This oscillator belongs to the IQXT-316 series from IQD Frequency Products. The series offers various frequencies and packages. IQD provides comprehensive frequency control solutions including crystals and oscillators for global markets.
Replacement Considerations
LFTVXO075807 is listed as a previous part number revision. Verify functional equivalence before substitution. Other models in the IQXT-316 series may offer different frequencies or packages.
