Oscillators Procurement Notes

Verify the specific suffix against official documentation to confirm electrical characteristics and pinout configuration. Ensure the ordering part number matches the required frequency and voltage specifications exactly. Cross-reference the manufacturer's latest datasheet to validate environmental ratings and package dimensions before finalizing procurement orders.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required for space-constrained designs. The LVCMOS output ensures compatibility with standard logic families. Consider the enable/disable feature if power management or clock gating is necessary within the target application architecture.

Oscillators Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronics, which focuses on small form factor timing solutions. The series utilizes quartz crystal technology to provide stable frequency outputs. The specific model integrates the resonator and driver circuitry into a single surface-mount package.

Oscillators Replacement Considerations

Direct substitutes require matching the 17.734 MHz frequency, 1.8V supply, and LVCMOS output type. Verify that any alternative component fits the 4-SMD no lead footprint and meets the -40°C to 85°C temperature range requirements.
