18QHTF21-87.000-OE

Overview

The 18QHTF21-87.000-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 87.000 MHz and utilizes LVCMOS output logic. The device is designed for low-voltage applications with a supply voltage of 1.8V. It features an Enable/Disable control function via the OE pin. The component is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes hardware enable/disable functionality for power management
• Utilizes a leadless SMD package for surface-mount assembly

Applications

• General clock signal generation in electronic circuits
• Timing reference sources for digital systems
• Embedded devices requiring precise frequency standards

Procurement Notes

Verify the specific suffix 'OE' to confirm the presence of the enable pin and LVCMOS output type. Ensure the 1.8V supply voltage requirement matches the target system design. Confirm the 4-SMD no-lead package footprint aligns with the PCB layout specifications before ordering.

Selection Notes

Select this component when a low-voltage 87 MHz clock source is required. Consider the enable feature if power cycling or clock gating is necessary. Verify that the LVCMOS output levels are compatible with the receiving logic inputs of the connected integrated circuits.

Part Context

This part belongs to the Mercury Electronics XO series, which offers various frequencies and voltage options. The 18QHTF21 series typically provides standard oscillators in small form factors. Other variants in this family may differ in frequency, voltage, or package size while maintaining similar functional characteristics.

Replacement Considerations

Direct substitutes must match the 87 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm package. Check manufacturer datasheets for equivalent parts from other vendors offering identical electrical and mechanical specifications.
