18QHTF21-1.1385-PD

Overview

The 18QHTF21-1.1385-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a fixed frequency of 1.1385 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 2.0mm x 1.6mm. This component serves as a precise clock source for electronic circuits requiring low-frequency timing signals.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes standby or power-down functionality to reduce consumption
• Utilizes a small 4-SMD no-lead surface-mount package

Applications

• General-purpose clock signal generation
• Low-frequency timing reference circuits
• Embedded systems requiring standby modes

Procurement Notes

Verify the specific ordering suffix and frequency tolerance against the official datasheet before procurement. Confirm that the 1.8V supply voltage aligns with the target system design. Ensure the 4-SMD no-lead package footprint matches the PCB layout requirements. Check for any specific handling instructions related to the surface-mount technology.

Selection Notes

Select this component when a 1.1385 MHz clock source is required with LVCMOS outputs. Consider the 1.8V operating voltage and the availability of a power-down feature for energy management. Evaluate the 2.0x1.6mm package size against spatial constraints. Compare performance metrics such as stability and phase noise if available in the manufacturer documentation.

Part Context

This part belongs to the 18QHTF21 series of oscillators from Mercury Electronic Ind., Co., Ltd. The series typically offers various frequencies within a standard XO format. The 'PD' suffix likely indicates the power-down capability. These components are designed for applications needing reliable timing in compact form factors.

Replacement Considerations

Consult the official Mercury Electronics Ind. Co., Ltd. documentation for direct substitutes. Verify that any replacement matches the 1.1385 MHz frequency, LVCMOS output, 1.8V supply, and 4-SMD package dimensions.
