18QHTF21-57.723667-OE

Overview

The 18QHTF21-57.723667-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a nominal frequency of 57.723667 MHz with an LVCMOS output logic level. The device is designed for low-voltage applications, utilizing a 1.8V supply voltage and featuring an enable/disable control function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm. The component exhibits a frequency stability of 50 ppm and has a maximum current supply of 24 mA, suitable for space-constrained electronic designs requiring precise timing signals.

Feature Summary

• Integrates enable/disable functionality for power management
• Utilizes LVCMOS output logic for digital interface compatibility
• Compact 4-SMD no-lead surface mount packaging

Applications

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

Procurement Notes

Verify the specific ordering suffix '-OE' against the manufacturer's official documentation to confirm the exact pinout, tolerance, and temperature range specifications. Ensure that the required operating temperature range and load capacitance match the target application design constraints before finalizing procurement orders.

Selection Notes

Select this component when a 57.723667 MHz clock source is required within a 2.0x1.6mm footprint. Consider the 1.8V supply requirement and LVCMOS output swing when designing the power and signal integrity layout. Evaluate the 50 ppm stability against the system's jitter and phase noise requirements.

Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which focuses on small-form-factor crystal oscillators. The series typically includes various frequencies and supply voltages, sharing common physical dimensions but differing in electrical characteristics such as frequency, stability, and output drive strength.

Replacement Considerations

Direct replacements must match the 57.723667 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify if alternative suffixes like '-PD' or other manufacturers' equivalents meet the 50 ppm stability and 24 mA max current specifications.
