18QHTF21-23.014-PD

Oscillators Overview

The 18QHTF21-23.014-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 23.014 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and includes a standby or power-down function to manage energy consumption. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6mm. This component is engineered for timing applications requiring precise clock signals within low-voltage digital systems.

Oscillators Feature Summary

• Supports LVCMOS output logic for standard digital interface compatibility
• Includes standby and power-down functionality for power management
• Utilizes a small 4-SMD no-lead surface mount package

Oscillators Applications

• General purpose clock signal generation in embedded systems
• Timing reference for low-voltage digital circuits
• Consumer electronics requiring compact oscillators

Oscillators Procurement Notes

Verify the specific frequency suffix matches the required 23.014 MHz design specification. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Ensure the 4-SMD no-lead package footprint corresponds to the PCB layout requirements. Check for any specific operating temperature range constraints defined in the official datasheet before finalizing the order.

Oscillators Selection Notes

Select this component when a 23.014 MHz clock source is required with LVCMOS outputs. The 1.8V operating voltage makes it suitable for modern low-power digital designs. The integrated power-down feature aids in battery-operated applications. The small 2.0x1.6mm package allows for high-density board layouts where space is limited compared to larger oscillator packages.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which offers various frequencies in a standardized 2.0x1.6mm SMD package. The series typically supports LVCMOS outputs and 1.8V operation. The '-PD' suffix indicates the inclusion of a power-down control pin, distinguishing it from standard continuous-operation variants within the same physical form factor.

Oscillators Replacement Considerations

Direct substitutes include other 18QHTF21 series parts with identical 23.014 MHz frequency and LVCMOS output, such as those without the PD suffix if power-down is not critical. Cross-manufacturer replacements must match the 2.0x1.6mm footprint, 1.8V supply, and LVCMOS logic levels.
