18QHTF21-3.832-PD

Oscillators Overview

The 18QHTF21-3.832-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 3.832 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes a standby function for power down control. It is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated standby mode for power management
• Compact 4-SMD no-lead surface mount package

Oscillators Applications

• General purpose clock generation
• Digital signal processing timing
• Microcontroller system clocks

Oscillators Procurement Notes

Verify the specific frequency suffix matches the required 3.832 MHz specification. Confirm the -PD suffix indicates the correct power-down functionality versus other variants like -OE. Ensure the 1.8V supply requirement aligns with the target circuit design before procurement.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a specific 3.832 MHz reference frequency. Consider the 4-SMD footprint constraints and the need for active standby control via the enable pin configuration inherent to the PD variant.

Oscillators Part Context

This part belongs to the 18QHTF21 series of standard oscillators from Mercury Electronics. The series offers various frequencies with consistent LVCMOS outputs and 1.8V operation. The -PD suffix distinguishes it from -OE variants, specifically defining the power-down capability rather than just enable/disable functionality.

Oscillators Replacement Considerations

Direct substitutes must match the 3.832 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD package. Verify that replacement parts also support the standby/power-down feature indicated by the PD suffix.
