Oscillators Procurement Notes

Verify the specific supply voltage and load capacitance requirements against your system design before procurement. Confirm that the selected variant matches the required frequency tolerance and stability specifications for your application environment. Ensure compatibility with your manufacturing process regarding the surface-mount package type. Cross-reference the manufacturer datasheet for detailed electrical characteristics and recommended soldering profiles to guarantee long-term reliability and performance consistency.

Oscillators Selection Notes

Select this component when high frequency stability over temperature is critical compared to standard crystals. Consider the trade-off between cost and performance relative to OCXOs or basic crystals. Evaluate the available supply voltage options to match your system's power rails. Assess the physical dimensions to ensure they fit within the designated PCB area. Verify that the output drive strength meets the input requirements of the downstream clock distribution network.

Oscillators Part Context

This part belongs to TXC Corporation's 7Q series of surface-mount TCXOs. The series is engineered for applications demanding superior frequency accuracy and stability compared to standard quartz crystals. These oscillators integrate the resonator and compensation circuitry into a single compact package. The 40 MHz frequency is commonly used as a reference clock for microprocessors, FPGAs, and communication interfaces.

Oscillators Replacement Considerations

Direct replacements must match the 40 MHz frequency, 4-SMD no-lead package, and CMOS output format. Verify that substitute parts offer equivalent or better temperature stability and supply voltage compatibility. Check pinout configurations to ensure electrical compatibility without PCB redesign. Consult manufacturer cross-reference lists for validated alternative part numbers from TXC or other suppliers.
