18QHTF21-86.900-PD

Overview

The 18QHTF21-86.900-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind., Co., Ltd. It operates at a fixed frequency of 86.9 MHz and utilizes LVCMOS output logic levels. The device is designed for low-power applications, featuring a supply voltage of 1.8V and a standby power-down mode. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Feature Summary

• LVCMOS output interface
• 1.8V supply voltage operation
• Standby power-down capability
• Compact 4-SMD no lead package

Applications

• Low-power electronic systems
• Timing reference for digital circuits
• Consumer electronics requiring small form factors

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD package footprint matches your PCB layout constraints. Check for any specific RoHS compliance documentation if required by your manufacturing standards.

Selection Notes

Select this component when a precise 86.9 MHz clock signal is needed with minimal power consumption. The LVCMOS output is suitable for direct interfacing with standard CMOS logic families. Consider the 1.8V operating voltage to ensure compatibility with low-voltage microcontrollers or FPGAs. The small 2.0x1.6mm package is ideal for space-constrained designs.

Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronic Ind., Co., Ltd. The series typically offers various frequencies within the same physical footprint. The 'PD' suffix indicates the inclusion of a power-down control feature, allowing for energy savings when the oscillator is not actively used.

Replacement Considerations

Direct replacements must match the 86.9 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and electrical characteristics such as phase noise and jitter specifications. Consult manufacturer cross-reference lists for verified equivalent parts.
