18QHTF21-1.415-PD

Overview

The 18QHTF21-1.415-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a fixed frequency of 1.415 MHz and utilizes LVCMOS output logic. The device supports a supply voltage of 1.8V and includes a standby or power-down function for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. The maximum supply current is specified as 21mA.

Feature Summary

• Integrates LVCMOS output logic for digital interface compatibility
• Includes standby mode capability to reduce power consumption
• Utilizes a leadless SMD package for surface-mount assembly

Applications

• General-purpose timing clock generation
• Embedded system microcontroller clocks
• Consumer electronics timing references

Procurement Notes

Verify the specific frequency suffix matches the required 1.415 MHz specification. Confirm that the 1.8V supply voltage aligns with the target circuit design. Ensure the 4-SMD no-lead package footprint corresponds to the PCB layout requirements. Check datasheet details for operating temperature range and load capacitance specifications before integration.

Selection Notes

Select this component when a low-frequency, low-voltage timing source is required. The LVCMOS output is suitable for standard digital logic families. Consider the small 2.0x1.6mm footprint for space-constrained designs. Verify that the 21mA current draw fits within the power budget constraints of the application.
