Oscillators Procurement Notes

Verify the specific frequency tolerance and operating temperature range against your system requirements before procurement. Confirm that the 1.8V supply voltage aligns with your board's power architecture. Ensure the 4-SMD no-lead footprint matches your PCB layout constraints. Cross-reference the part number suffix to confirm the exact variant specifications provided by the manufacturer.

Oscillators Selection Notes

Select this component when a 36.828 MHz clock source is required for LVCMOS-compatible circuits. The 1.8V operating voltage makes it suitable for modern low-power designs. Consider the physical size constraints as the 2.0x1.6 mm package is small. Evaluate the need for a power-down feature if energy efficiency during idle states is a priority for the application.

Oscillators Part Context

This oscillator belongs to the QHTF series from Mercury Electronics, which focuses on small-sized SMD oscillators. The series typically offers various frequencies and supply voltages. The 'PD' suffix indicates the inclusion of a power-down control pin, allowing the user to disable the output to save power. This family is designed for high reliability in consumer and industrial electronics.

Oscillators Replacement Considerations

Direct replacements must match the 36.828 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm footprint. Verify pinout compatibility, especially regarding the power-down control signal. Check if alternative manufacturers offer equivalent performance metrics such as phase noise and stability within the same package type.
