18QHTF21-10.230-PD

Overview

The 18QHTF21-10.230-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 10.23 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features a standby power-down mode for energy efficiency. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm.

Feature Summary

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

Applications

• General clock signal generation
• Embedded system timing references
• Portable electronic devices requiring low power consumption

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure the 1.8V supply rail stability meets the oscillator specifications. Confirm that the 4-SMD no-lead package footprint aligns with your PCB layout constraints to ensure proper soldering and mechanical reliability during assembly.

Selection Notes

Select this component when a precise 10.23 MHz reference is required with minimal power usage. The LVCMOS output is suitable for direct interfacing with digital logic families operating at 1.8V. Consider the small form factor for space-constrained designs where standard leaded packages cannot fit within the available board area.

Part Context

This model belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz frequency control products. The series includes various frequencies and voltage options, all sharing the same compact 2.0x1.6 mm SMD package. Mercury Electronics has been a pioneer in the crystal industry since 1973, providing reliable oscillators for global markets.

Replacement Considerations

Direct substitutes must match the 10.23 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and electrical characteristics such as phase noise and jitter if critical to the application.
