18QHTF21-23.3042-PD

Oscillators Overview

The 18QHTF21-23.3042-PD is a crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 23.3042 MHz with LVCMOS output logic. The device supports a supply voltage of 1.8V and features a Standby (Power Down) function. It is housed in a 4-SMD, No Lead package with dimensions of 2.0x1.6mm.

Oscillators Feature Summary

• Supports Low Voltage CMOS (LVCMOS) output logic for digital interfacing.
• Includes a Standby or Power Down mode to reduce power consumption when inactive.

Oscillators Applications

• General clock signal generation in electronic circuits
• Timing reference for low-voltage digital systems
• Embedded systems requiring 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 voltage aligns with your system's power rails. Ensure the 4-SMD no-lead package footprint matches your PCB layout constraints. Check for RoHS compliance status if required by your manufacturing standards.

Oscillators Selection Notes

Select this component when a precise 23.3042 MHz timing source is needed in a minimal space-constrained environment. The LVCMOS interface simplifies integration with standard logic families. The standby feature offers energy efficiency benefits for battery-operated or power-sensitive applications compared to continuously running oscillators.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which focuses on small-form-factor crystal oscillators. The series typically includes various frequencies within the same physical package size. The 'PD' suffix likely indicates the presence of a power-down control pin or feature, distinguishing it from standard continuous-operation variants.

Oscillators Replacement Considerations

Direct replacements must match the 23.3042 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm 4-SMD package. Verify electrical compatibility and pinout configuration before substituting. Generic equivalents may differ in phase noise or stability specifications.
