Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no lead footprint matches your PCB layout constraints. Request the official datasheet from Mercury Electronics for precise electrical characteristics and reliability data.

Oscillators Selection Notes

Select this component when a precise 47.92323 MHz clock source is required with low-voltage operation. The LVCMOS output ensures compatibility with standard digital logic families. Consider the standby feature if power efficiency during idle states is a priority. Verify thermal performance within the specified operating temperature range for your application environment.

Oscillators Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series offers various frequencies with consistent LVCMOS outputs and 1.8V operation. The 'PD' suffix typically indicates the inclusion of a power-down control pin, enhancing system power management capabilities compared to standard variants.

Oscillators Replacement Considerations

Direct substitutes must match the 47.92323 MHz frequency, LVCMOS output, 1.8V supply, and 4-SMD no lead package. Check Mercury Electronics documentation for equivalent parts within the same series. Cross-reference with other manufacturers only if pinout and electrical parameters are identical.
