18QHTF21-112.310-PD

Overview

The 18QHTF21-112.310-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 112.31 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 2.0 x 1.6 mm.

Feature Summary

• Integrates LVCMOS output logic for standard digital interface compatibility
• Features a dedicated standby or power-down mode to reduce power consumption
• Utilizes a small form factor 4-SMD no lead package design

Applications

• General clock signal generation in electronic circuits
• Data communication systems requiring precise timing references
• Embedded systems utilizing low-voltage digital interfaces

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm pinout and electrical characteristics. Ensure the selected variant matches the required supply voltage and output logic levels for the target application circuit.

Selection Notes

Select this component when a low-profile surface-mount oscillator is required for 1.8V logic systems. Consider the 2.0x1.6mm footprint constraints and the necessity for a power-down feature during system design phases.
