18QHTF21-23.5122-OE

Oscillators Overview

The 18QHTF21-23.5122-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 23.5122 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and features an enable/disable control function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm. The component is RoHS compliant and classified under Moisture Sensitivity Level (MSL) 1, indicating unlimited exposure to ambient conditions.

Oscillators Feature Summary

• Supports enable/disable functionality for power management
• Utilizes LVCMOS output logic for digital interface compatibility
• RoHS compliant construction for environmental standards

Oscillators Applications

• General purpose clock signal generation
• Digital circuit timing reference
• Embedded system clock sources

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target application design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the 4-SMD no-lead package footprint matches the PCB layout constraints. Check for any specific storage or handling requirements related to the MSL classification during assembly processes.

Oscillators Selection Notes

Select this component when a low-voltage, small-footprint clock source is required for digital interfaces. The LVCMOS output is suitable for direct connection to CMOS-compatible inputs without additional buffering. Consider the enable pin feature if dynamic power saving is necessary. Verify that the operating temperature range meets the environmental conditions of the final product deployment.

Oscillators Part Context

This part belongs to the QHTF series of surface mount oscillators from Mercury Electronics. The series is characterized by small physical dimensions and low power consumption. The 'OE' suffix typically denotes the enable/disable capability. This family is designed for applications requiring precise timing in space-constrained electronic devices.

Oscillators Replacement Considerations

Direct substitutes must match the 23.5122 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify electrical parameters such as jitter and phase noise specifications to ensure functional equivalence in high-speed digital circuits.
