Oscillators Procurement Notes

Verify the specific suffix 'OE' against the manufacturer's current datasheet to confirm pinout and electrical characteristics match the target design requirements. Ensure the 3.3V supply rail stability meets the oscillator's noise sensitivity specifications. Confirm that the 4-SMD no-lead package soldering profile aligns with the assembly process capabilities. Cross-reference the part number with authorized distributors to avoid counterfeit components.

Oscillators Selection Notes

Select this component when a precise 1.832 MHz timing source is required within strict spatial limitations. The LVCMOS output eliminates the need for additional level-shifting circuitry in compatible logic families. The enable/disable feature supports power management strategies in battery-operated devices. Consider the operating temperature range and load capacitance requirements relative to the host system's environmental conditions and trace layout.

Oscillators Part Context

The 3QHTF21 series represents Mercury Electronics' standard XO lineup, offering various frequencies in a unified small form factor. This specific model targets applications needing a stable 1.832 MHz reference. The series shares common packaging and logical interface standards, allowing for design flexibility across different frequency requirements while maintaining consistent board layout practices.

Oscillators Replacement Considerations

Direct substitutes include other 1.832 MHz LVCMOS oscillators in 2.0x1.6mm packages from manufacturers such as Epson or SiTime. Verify equivalent frequency tolerance, phase noise, and supply voltage compatibility before substitution. Ensure the replacement part maintains the same enable/disable pin configuration if power management is critical.
