18QHTF21-46.875-PD

Oscillators Overview

The 18QHTF21-46.875-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 46.875 MHz and utilizes LVCMOS output logic. The device is designed for low-power applications, featuring a supply voltage of 1.8V and a standby power-down mode to reduce energy consumption during inactive periods. It is housed in a compact 4-SMD, no-lead package with dimensions of 2.0mm x 1.6mm, suitable for space-constrained surface-mount designs.

Oscillators Feature Summary

• Integrates LVCMOS output logic for direct digital interface compatibility
• Supports power-down standby mode for enhanced energy efficiency
• Utilizes a compact 4-SMD no-lead surface-mount package

Oscillators Applications

• Portable electronic devices requiring low power consumption
• Communication systems utilizing standard clock frequencies
• Embedded control circuits needing precise timing references

Oscillators Procurement Notes

Verify the specific operating temperature range and load capacitance requirements against your system design before procurement. Ensure that the 1.8V supply voltage aligns with your target platform's power rails. Confirm that the LVCMOS output swing is compatible with the input thresholds of the receiving logic components to guarantee signal integrity.

Oscillators Selection Notes

Select this component when a 46.875 MHz reference is required in a minimal footprint. Consider the 1.8V operation if power management is critical. Compare the 4-SMD package size against available board space. Evaluate the standby current specifications if the application involves frequent sleep cycles to ensure optimal battery life or thermal performance.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount oscillators from Mercury Electronics. The series typically offers various frequency options within a standardized physical envelope. The 'PD' suffix indicates the inclusion of a power-down control feature, distinguishing it from continuous-operation variants in the same family.

Oscillators Replacement Considerations

Direct replacements must match the 46.875 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility and electrical characteristics such as phase noise and jitter specifications to ensure functional equivalence in the target circuit.
