18QHTF21-83.125-PD

Overview

The 18QHTF21-83.125-PD is a standard crystal oscillator manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 83.125 MHz and utilizes LVCMOS output logic levels. The device is designed for a supply voltage of 1.8V and features a power-down function via a standby control input. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6 mm, suitable for surface-mount applications requiring precise timing signals.

Feature Summary

• Supports LVCMOS output interface for digital circuit compatibility
• Includes standby mode for power management via power-down control
• Utilizes quartz crystal technology for stable frequency generation

Applications

• Digital signal processing systems
• Communication equipment clocking
• Embedded system timing references

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before procurement. 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 any RoHS compliance documentation if required by your manufacturing standards.

Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a standard LVCMOS interface. The small 2.0x1.6 mm package makes it suitable for space-constrained designs. Consider the power-down feature if energy efficiency during idle states is a priority. Verify that the 83.125 MHz frequency meets the exact timing needs of the target application without requiring external dividers.

Part Context

This part belongs to the Mercury Electronic 18QHTF21 series of surface-mount crystal oscillators. The series offers various frequencies and voltage options within a standardized small outline package format. Mercury Electronic is a established manufacturer of frequency control products, including crystals and oscillators, with a focus on providing reliable timing solutions for electronic devices.

Replacement Considerations

Direct substitutes may include other 83.125 MHz LVCMOS oscillators in a 2.0x1.6mm SMD package from different manufacturers, provided they support 1.8V operation and have compatible pinouts. Verify electrical parameters such as phase noise and jitter specifications to ensure equivalent performance.
