QTS750C-40.000MBP-T

Overview

The QTS750C-40.000MBP-T is a temperature-compensated crystal oscillator (TCXO) manufactured by QST Products, LLC. It operates at a nominal frequency of 40.000 MHz and utilizes CMOS output logic. The component is housed in a compact 4-SMD, no-lead package with dimensions of 7.0 x 5.0 mm. It features a maximum frequency stability of ±4.6 ppm and supports a supply voltage range typically associated with the series, such as 3.3V. The device is designed for applications requiring high precision and long-term free-run stability.

Feature Summary

• Temperature compensation ensures stable frequency performance across varying environmental conditions.
• CMOS output interface provides compatibility with standard digital logic circuits.
• Compact surface-mount package facilitates automated assembly and space-constrained designs.

Applications

• Telecommunications equipment requiring precise clock synchronization
• Consumer electronics utilizing high-frequency data transmission
• Industrial control systems needing reliable timing references

Procurement Notes

Verify the specific operating voltage and load capacitance requirements against your circuit design before procurement. Confirm that the 4-SMD package footprint matches your PCB layout constraints. Ensure the supplier provides original manufacturer documentation to guarantee authenticity and performance specifications.

Selection Notes

Select this model when a 40 MHz reference signal with ±4.6 ppm stability is required. Consider the CMOS output type for direct interfacing with microcontrollers or FPGAs. Evaluate the thermal environment to ensure the TCXO maintains its specified accuracy without additional cooling measures.

Part Context

This component belongs to the QTS750C series of quartz-based oscillators from QST Products. The series includes various frequencies and packages, offering solutions for timing applications where size and stability are critical factors. The 40.000 MHz variant serves as a common clock source for communication protocols.

Replacement Considerations

Direct substitutes include other QTS750C variants with different frequencies if the system allows reconfiguration. Cross-brand replacements must match the 4-SMD footprint, CMOS output, and ±4.6 ppm stability specification to ensure functional equivalence.
