18QHTF21-69.102-PD

Overview

The 18QHTF21-69.102-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 69.102 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a standby or power-down mode capability. It is housed in a compact 4-SMD, no lead package with dimensions of 2.0x1.6mm.

Feature Summary

• Supports low-voltage operation at 1.8V
• Includes standby and power-down functionality
• Utilizes LVCMOS output interface

Applications

• Battery-powered portable devices
• General electronic timing circuits
• Digital signal processing systems

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply rail is stable and within the specified operating range to ensure reliable oscillator performance. Ensure the PCB footprint matches the 4-SMD no-lead package dimensions for proper assembly.

Selection Notes

Select this component when a precise 69.102 MHz clock signal is required for LVCMOS-compatible digital logic. Consider the 1.8V supply constraint and the need for power management features like standby mode. Evaluate the small form factor suitability for space-constrained designs compared to larger oscillator packages.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronic Ind. Co., Ltd., a supplier specializing in quartz crystals and oscillators. The series typically offers various frequencies within a standardized 2.0x1.6mm SMD package. This specific model provides a unique frequency point for applications requiring exact timing synchronization.

Replacement Considerations

Direct substitutes must match the 69.102 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pinout compatibility and thermal characteristics. Cross-reference with other manufacturers offering similar low-profile oscillators if Mercury stock is unavailable.
