18QHTF21-13.530-OE

Overview

The 18QHTF21-13.530-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 13.53 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and features an active enable/disable control function via the OE pin. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes active enable/disable functionality through the OE pin
• Designed for low-voltage operation at 1.8V
• Utilizes a compact 4-SMD no-lead surface mount package

Applications

• General clock signal generation in embedded systems
• Timing reference for digital communication interfaces
• Clock source for microcontrollers and FPGAs

Procurement Notes

Verify that the specific ordering suffix matches the required enable/disable configuration and output load specifications. Confirm the package footprint aligns with the PCB design guidelines for 4-SMD no-lead components. Ensure the supply voltage requirements are compatible with the target system's 1.8V rail before finalizing procurement orders.

Selection Notes

Select this component when a precise 13.53 MHz timing reference is required for low-power applications. The integrated enable/disable feature allows for power management strategies in battery-operated devices. Consider the small form factor suitable for space-constrained designs requiring standard LVCMOS signaling levels.

Part Context

This oscillator belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz-based frequency control products. The manufacturer has decades of experience in Taiwan producing crystals and oscillators. This series typically offers standard performance characteristics suitable for general-purpose timing applications across various electronic industries.

Replacement Considerations

Direct substitutes must match the 13.53 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify electrical parameters such as load capacitance and drive level compatibility. Check if alternative manufacturers offer equivalent enable/disable functionality within the same physical footprint constraints.
