18QHTF21-30.230-PD

Oscillators Overview

The 18QHTF21-30.230-PD is a crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a standard frequency of 30.23 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features a power-down (standby) function for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm.

Oscillators Feature Summary

• Supports low-voltage operation at 1.8V
• Includes standby mode capability via power-down control
• Utilizes LVCMOS output interface for digital compatibility

Oscillators Applications

• Portable electronic devices requiring low power consumption
• Communication modules utilizing standard clock frequencies
• Embedded systems needing compact surface-mount oscillators

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before ordering. Confirm that the 1.8V supply rail is stable within the datasheet specifications to ensure reliable oscillator startup. Ensure the PCB footprint matches the 2.0x1.6mm SMD package dimensions precisely to avoid assembly issues.

Oscillators Selection Notes

Select this component when a 30.23 MHz reference clock is required in space-constrained applications. The choice is driven by the need for low voltage operation and the availability of a power-down feature. Consider the package size constraints and the compatibility of LVCMOS signals with the target microcontroller or FPGA inputs.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz crystal frequency control products. The manufacturer has decades of experience in Taiwan's quartz industry.
