18QHTF21-85.932-PD

Overview

The 18QHTF21-85.932-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 85.932 MHz and utilizes LVCMOS output logic. 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

• LVCMOS output logic interface
• Standby (Power Down) control capability
• Compact 4-SMD No Lead surface mount package

Applications

• General purpose clock signal generation
• Embedded systems requiring low power standby modes
• Consumer electronics with space constraints

Procurement Notes

Verify the specific ordering suffix to confirm the presence of the Standby (Power Down) feature, as indicated by the PD designation. Ensure compatibility with 1.8V logic levels and LVCMOS requirements. Confirm the 85.932 MHz frequency specification matches the design intent. Check package dimensions against PCB footprint guidelines.

Selection Notes

Select this component when a precise 85.932 MHz clock source is required with low voltage operation. The Standby feature makes it suitable for battery-powered applications where power conservation during idle periods is critical. The small 2.0x1.6mm package allows for high-density board layouts.
