18QHTF21-15.700-OE

Oscillators Overview

The 18QHTF21-15.700-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a nominal frequency of 15.7 MHz and utilizes an LVCMOS output signal format. The device is designed for low-power applications, featuring a supply voltage of 1.8V. It includes an enable/disable control function to manage power consumption. The component is housed in a compact 4-SMD, No Lead package, suitable for surface-mount assembly on printed circuit boards.

Oscillators Feature Summary

• LVCMOS output interface for digital logic compatibility
• Enable/disable pin for power management control
• Low voltage operation at 1.8V
• Compact 4-SMD no-lead surface mount package

Oscillators Applications

• General purpose clock generation in embedded systems

• Communication interface synchronization circuits

Oscillators Procurement Notes

Verify the specific ordering suffix OE against the manufacturer's current datasheet to confirm active status and exact electrical tolerances. Ensure the 1.8V supply requirement aligns with the target system design. Confirm that the enable/disable functionality meets the power management strategy. Check for any recent revisions to the 4-SMD package dimensions prior to PCB layout finalization.

Oscillators Selection Notes

Select this component when a precise 15.7 MHz timing source is required with low power consumption capabilities. The LVCMOS output is suitable for direct interfacing with standard digital logic families operating at 1.8V. Consider the enable/disable feature if dynamic power saving is necessary. Evaluate the 4-SMD footprint constraints against available board space.
