18QHTF21-7.870-PD

Overview

The 18QHTF21-7.870-PD is a crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 7.87 MHz and utilizes LVCMOS output logic. The device requires a 1.8V supply voltage and features a standby mode for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Feature Summary

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

Applications

• Battery-powered portable devices
• Compact electronic systems requiring low power consumption
• Clock signal generation in small form-factor circuits

Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required voltage levels and output types. Confirm package dimensions against board space constraints. Check manufacturer documentation for operating temperature ranges and electrical specifications prior to integration.

Selection Notes

Select this component for applications requiring a small footprint and low voltage operation. Ensure the system design supports the 1.8V supply requirement. Consider the LVCMOS output compatibility with downstream logic circuits. Verify thermal performance within the specified operating range.

Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies and packages designed for modern electronics. The 'PD' suffix typically indicates power-down capability, enhancing energy efficiency in portable designs.

Replacement Considerations

Direct substitutes include other 18QHTF21 variants with matching frequencies such as 18QHTF21-7.870 without the PD suffix if power-down is not needed. Cross-reference with similar 2.0x1.6mm LVCMOS oscillators from other manufacturers ensuring identical pinout and voltage requirements.
