18QHTF21-49.5133-PD

Oscillators Overview

The 18QHTF21-49.5133-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a nominal frequency of 49.5133 MHz and utilizes LVCMOS output logic. The device is designed for surface mount installation in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. It functions with a supply voltage of 1.8V and includes a standby or power-down feature to manage energy consumption during inactive periods.

Oscillators Feature Summary

• Supports low-voltage operation at 1.8V with LVCMOS interface compatibility
• Integrates a power-down mode for reduced standby current consumption
• Utilizes a small-footprint SMD package suitable for space-constrained designs

Oscillators Applications

• General-purpose clock signal generation in embedded systems
• Timing reference sources for digital communication interfaces
• Clock distribution in portable electronic devices requiring low power

Oscillators Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct frequency and package configuration. Confirm that the LVCMOS output type matches the receiving circuit requirements. Check for RoHS compliance status if environmental regulations apply to the final assembly. Ensure the operating temperature range aligns with the intended application environment.

Oscillators Selection Notes

Select this component when a precise 49.5133 MHz timing source is required within a limited board area. The 1.8V supply requirement makes it suitable for modern low-power logic families. Consider the 2.0x1.6mm footprint constraints during layout design. Evaluate the need for power-down functionality if battery life or thermal management is critical for the system.

Oscillators Part Context

This oscillator belongs to the Mercury Electronic XO series, which provides standard frequency control solutions. The company has a history of manufacturing quartz-based frequency products. This specific model represents a surface-mount variant designed for high-volume consumer and industrial electronics applications requiring reliable timing signals.

Oscillators Replacement Considerations

Direct substitutes must match the 49.5133 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm SMD package. Verify pinout compatibility and electrical characteristics before integration. Cross-reference with other manufacturers offering similar small-form-factor oscillators.
