18QHTF21-7.0333-PD

Overview

The 18QHTF21-7.0333-PD is a crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 7.0333 MHz with an LVCMOS output logic type. The device requires a 1.8V supply voltage and features a Standby (Power Down) control function for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm.

Feature Summary

• Supports low-voltage operation at 1.8V
• Includes standby control functionality
• Utilizes LVCMOS output interface

Applications

• Battery-powered electronic devices
• Portable consumer electronics
• General-purpose clock signal generation

Procurement Notes

Verify the specific suffix 'PD' to confirm the presence of the Standby (Power Down) control feature. Ensure that the 1.8V supply voltage requirement aligns with the target system's power rails. Confirm the 2.0x1.6mm footprint matches the PCB layout design before finalizing procurement.

Selection Notes

Select this component when a low-profile 4-pin SMD oscillator is required for 1.8V logic systems. The inclusion of a standby pin makes it suitable for applications requiring active power management. Consider the 7.0333 MHz frequency specifically for timing requirements matching this value.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies and voltage options. The 'PD' suffix distinguishes it from variants with Enable/Disable controls or different voltage levels like 3.3V. It represents a standard XO solution within their portfolio.

Replacement Considerations

Direct substitutes must match the 7.0333 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify if alternative manufacturers offer equivalent standby functionality and electrical characteristics.
