18QHTF21-109.620-PD

Overview

The 18QHTF21-109.620-PD is a crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 109.62 MHz with LVCMOS output logic. The device requires a 1.8V supply voltage and features a power-down standby function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.

Feature Summary

• Supports LVCMOS output logic for standard digital interfacing
• Includes power-down standby functionality to reduce consumption
• Utilizes a small form factor 4-SMD no lead package

Applications

• General clock signal generation in electronic circuits
• Data communication systems requiring precise timing
• Embedded systems utilizing LVCMOS interfaces

Procurement Notes

Verify the specific ordering suffix PD against manufacturer documentation to ensure correct packaging configuration. Confirm that the 1.8V supply requirement aligns with system design constraints. Check datasheet for exact operating temperature range and load capacitance specifications before integration.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a minimal footprint. The LVCMOS output is suitable for standard logic families. Ensure the PCB layout accommodates the 2.0x1.6mm SMD package dimensions and provides adequate thermal relief for the no-lead termination style.

Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series offers various frequencies within a standardized 2.0x1.6mm package. The -PD suffix typically denotes specific packaging or tape-and-reel configurations provided by the manufacturer.

Replacement Considerations

Direct substitutes must match the 109.62 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm package size. Verify pinout compatibility and electrical characteristics with alternative manufacturers' equivalent parts.
