Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure the 1.8V supply rail stability meets the oscillator's operational specifications. Confirm that the PCB footprint matches the 2.0x1.6mm SMD package dimensions to avoid assembly issues. Check for any specific handling instructions regarding electrostatic discharge protection during installation.

Oscillators Selection Notes

Select this component when a 35.2 MHz reference clock is required with minimal power usage. The LVCMOS interface ensures compatibility with standard logic families. Consider the physical size constraints of the application, as the small form factor suits space-limited designs. Verify that the operating temperature range aligns with the environmental conditions of the target system.

Oscillators Part Context

This model belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series typically offers various frequencies with consistent electrical characteristics. The 'PD' suffix indicates the inclusion of a power-down feature. These components are part of Mercury's portfolio of frequency control products established since 1973.

Oscillators Replacement Considerations

Direct substitutes must match the 35.2 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pinout compatibility and thermal characteristics. Cross-reference with other manufacturers offering similar XO specifications if availability is an issue.
