18QHTF21-57.730333-PD

Overview

The 18QHTF21-57.730333-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 57.730333 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and supports a standby or power-down function for energy management. It is housed in a compact 4-SMD, no-lead package with dimensions of 2.0mm x 1.6mm.

Feature Summary

• Supports standby mode via power-down control signal
• Utilizes low-voltage LVCMOS output interface
• Compact surface-mount form factor

Applications

• Digital clock distribution systems
• Data communication interfaces
• Embedded processor clock sources

Procurement Notes

Verify the specific suffix 'PD' confirms the power-down capability as documented. Ensure the operating temperature range and load capacitance requirements match the target circuit design. Confirm the 4-SMD no-lead package compatibility with assembly processes before finalizing procurement orders.

Selection Notes

Select this component when a precise 57.730333 MHz reference is required in space-constrained designs. The 1.8V supply voltage makes it suitable for modern low-power digital circuits. The integrated power-down feature allows for system-level energy optimization during idle states.

Part Context

This part belongs to the 18QHTF21 series of quartz oscillators from Mercury Electronics. The series offers various frequencies and supply voltages. The 'PD' suffix specifically denotes the inclusion of a power-down pin for active control of the oscillator state.

Replacement Considerations

Direct substitutes must match the 57.730333 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm package. Verify pinout compatibility for the power-down function when considering alternative manufacturers.
