18QHTF21-32.571-PD

Oscillators Overview

The 18QHTF21-32.571-PD is a crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 32.571 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and features a standby power-down mode. It is housed in a compact 4-SMD, no-lead package with dimensions of 2.0x1.6 mm.

Oscillators Feature Summary

• Supports low-voltage operation at 1.8V
• Includes standby power-down functionality
• Utilizes LVCMOS output logic for digital interfacing

Oscillators Applications

• General-purpose clock signal generation
• Embedded system timing references
• Digital circuit synchronization

Oscillators Procurement Notes

Verify the specific supply voltage requirement against your system design, as datasheets may list variations such as 3.3V or 1.8V for this series. Confirm that the LVCMOS output level matches your receiving logic thresholds. Ensure the 2.0x1.6 mm footprint aligns with your PCB layout constraints before finalizing procurement.

Oscillators Selection Notes

Select this component when a precise 32.571 MHz reference is required in space-constrained designs. The choice depends on compatibility with 1.8V logic families and the necessity for power management via the standby pin. Evaluate thermal performance and load capacitance requirements to ensure stable oscillation within the operating temperature range.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies and voltage options in a standardized small outline package. The 'PD' suffix indicates the inclusion of a power-down control feature, distinguishing it from standard continuous-operation variants within the same form factor.

Oscillators Replacement Considerations

Direct substitutes must match the 32.571 MHz frequency, 1.8V supply, and LVCMOS output. Verify pinout compatibility for the 4-SMD no-lead package. Alternative models from other manufacturers require careful evaluation of load capacitance and drive strength specifications to ensure functional equivalence.
