18QHTF21-13.535-OE

Overview

The 18QHTF21-13.535-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 13.535 MHz and utilizes LVCMOS output logic. The device functions with a supply voltage of 1.8V and includes an enable/disable control feature for power management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated enable/disable pin for power control
• Compact 4-SMD no-lead surface mount package

Applications

• Timing and clock signal generation in electronic devices
• General purpose timing applications requiring standard XO performance

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead footprint matches your PCB layout constraints. Check for any specific operating temperature range limitations defined in the official datasheet to guarantee reliability under your environmental conditions.

Selection Notes

Select this component when a precise 13.535 MHz reference is required with low-voltage operation. The LVCMOS output is suitable for direct interfacing with digital logic families. Consider the small form factor for space-constrained designs. Verify that the enable/disable functionality meets your power sequencing needs. Compare against other Mercury oscillators if different frequencies or voltages are needed.
