18QHTF21-36.5568-OE

Oscillators Overview

The 18QHTF21-36.5568-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 36.5568 MHz with an LVCMOS output logic level. The device requires a 1.8V supply voltage and features enable/disable functionality for power management. Frequency stability is specified at ±50ppm over the operating temperature range of -40°C to +85°C. The component is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm.

Oscillators Feature Summary

• Supports active low or high enable/disable control for power optimization
• Provides stable LVCMOS clock signals for digital circuit synchronization
• Designed for operation across extended industrial temperature ranges

Oscillators Applications

• Embedded system clock generation
• Consumer electronics timing references
• Industrial control unit synchronization

Oscillators Procurement Notes

Verify the specific frequency suffix matches the required 36.5568 MHz specification. Confirm that the 1.8V supply voltage aligns with the target system design. Ensure the 4-SMD no-lead package footprint corresponds to the PCB layout requirements. Check for any specific handling instructions regarding electrostatic discharge sensitivity during assembly.

Oscillators Selection Notes

Select this component when a precise 36.5568 MHz reference is needed with low power consumption. The ±50ppm stability suits general digital applications rather than high-precision RF systems. Consider the small 2.0x1.6mm footprint for space-constrained designs. Verify compatibility with LVCMOS input thresholds of downstream components.

Oscillators Part Context

This part belongs to the Mercury Electronics SMD oscillator series, utilizing quartz resonator technology. The model number indicates the 1.8V supply variant within the QHTF family. These oscillators are designed to replace discrete crystal and oscillator circuits, offering integrated solutions for timing needs in modern electronic devices.

Oscillators Replacement Considerations

Direct substitutes must match the 36.5568 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify equivalent stability and temperature range specifications before substitution.
