18QHTF21-47.850-OE

Oscillators Overview

The 18QHTF21-47.850-OE is a quartz crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 47.85 MHz and utilizes LVCMOS output logic. 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 2.0mm x 1.6mm. The component is designed for standard clock applications within specified operating temperature ranges.

Oscillators Feature Summary

• Supports enable/disable functionality for power management
• Utilizes LVCMOS output logic for digital interfacing
• Compact surface-mount design suitable for space-constrained PCB layouts

Oscillators Applications

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

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target application's datasheet specifications. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the 4-SMD package footprint matches the PCB silkscreen and copper pad design to guarantee proper soldering and mechanical stability during assembly processes.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a precise 47.85 MHz reference frequency. Consider the small 2.0x1.6mm form factor for high-density board designs. Evaluate the need for active enable/disable controls to optimize system power consumption during idle states compared to continuously running oscillators.

Oscillators Part Context

This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series typically offers various standard frequencies with consistent electrical characteristics. The suffix OE indicates specific packaging or tape-and-reel configuration options available from distributors. This family targets cost-sensitive consumer and industrial electronics requiring reliable timing signals.

Oscillators Replacement Considerations

Direct substitutes must match the 47.85 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package dimensions. Verify pin compatibility and electrical parameters before substitution.
