3QHTF21-16.6665-PD

Oscillators Overview

The 3QHTF21-16.6665-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind., Co., Ltd. It operates at a nominal frequency of 16.6665 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 3.3V and features a power-down function via a standby control pin. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0x1.6mm.

Oscillators Feature Summary

• Supports low-voltage operation at 3.3V with LVCMOS output compatibility
• Includes a dedicated standby mode for power-down functionality
• Utilizes a base crystal resonator for frequency stability

Oscillators Applications

• General clock signal generation in electronic circuits
• Embedded systems requiring precise timing references
• Communication modules utilizing standard frequency inputs

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Ensure that the 3.3V supply voltage aligns with your system's power rails. Confirm that the 2.0x1.6mm SMD footprint matches your PCB layout constraints. Check for any specific operating temperature range limitations defined in the official datasheet to ensure reliability under your intended environmental conditions.

Oscillators Selection Notes

Select this component when a small form factor is required alongside standard LVCMOS interface compatibility. The integrated power-down feature makes it suitable for battery-operated devices where standby current reduction is critical. Consider the 16.6665 MHz frequency specifically if it matches your system clock divider requirements or communication protocol standards without additional frequency synthesis.

Oscillators Part Context

This part belongs to the 3QHTF21 series from Mercury Electronics, which focuses on miniature surface-mount oscillators. The series typically offers various frequency options within a consistent 2.0x1.6mm package. The 'PD' suffix indicates the inclusion of a power-down control capability, distinguishing it from continuous-operation variants in the same physical footprint family.

Oscillators Replacement Considerations

Direct substitutes must match the 16.6665 MHz frequency, 3.3V supply, LVCMOS output, and 2.0x1.6mm package. Verify that alternative sources provide identical pinout configurations and electrical characteristics to ensure board-level compatibility without redesign.
