18QHTF21-86.913-PD

Overview

The 18QHTF21-86.913-PD is a quartz crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a nominal frequency of 86.913 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a Standby (Power Down) control function to manage power consumption. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm. This component serves as a standard clock source for digital circuits requiring precise timing signals.

Feature Summary

• LVCMOS output logic for standard digital interface compatibility
• Integrated standby mode for power management
• Compact surface-mount package design

Applications

• Digital signal processing systems
• Communication equipment clocking
• Embedded system timing references

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system's power rails. Ensure the PCB footprint matches the 4-SMD, No Lead package dimensions to guarantee proper soldering and mechanical stability during assembly processes.

Selection Notes

Select this oscillator when a low-voltage 1.8V operation is required alongside a specific 86.913 MHz frequency. Consider the LVCMOS output type for direct interfacing with standard logic families. Evaluate the need for the standby feature if power efficiency is a critical design constraint compared to continuous oscillation alternatives.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in SMD oscillators. The series typically offers various frequencies within a small form factor. The 'PD' suffix indicates the inclusion of a power-down pin or functionality, distinguishing it from non-standby variants in the same physical package family.

Replacement Considerations

Direct substitutes must match the 86.913 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm package. Verify pinout compatibility for the standby control signal. Cross-reference with other manufacturers offering identical electrical specifications and thermal characteristics to ensure functional equivalence.
