18QHTF21-15.960-PD

Oscillators Overview

The 18QHTF21-15.960-PD is a crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a frequency of 15.960 MHz with an LVCMOS output logic level. The device supports a supply voltage of 1.8V and includes a standby or power-down function for energy management. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. This component is designed for applications requiring precise clock signals in space-constrained electronic systems.

Oscillators Feature Summary

• Integrated LVCMOS output interface for standard digital logic compatibility
• Includes standby mode capability to reduce power consumption during idle periods
• Compact surface-mount package design suitable for high-density PCB layouts

Oscillators Applications

• General-purpose clock signal generation in embedded systems
• Timing reference for microcontrollers and processors
• Data communication interfaces requiring stable frequency sources

Oscillators Procurement Notes

Verify the specific ordering suffix '-PD' against the manufacturer's current datasheet to confirm the presence of the power-down feature. Ensure the supply voltage requirement of 1.8V aligns with your system design. Cross-reference the package dimensions (2.0x1.6mm) with your PCB footprint library to guarantee mechanical compatibility before finalizing procurement.

Oscillators Selection Notes

Select this component when a low-voltage 1.8V operation is required alongside a small form factor. The LVCMOS output is suitable for direct interfacing with standard CMOS logic families. Consider the power-down feature if system-level power management is a priority. Verify that the 15.960 MHz frequency meets the specific timing requirements of the target application circuit.

Oscillators Part Context

This part belongs to the 18QHTF21 series from Mercury Electronics, which specializes in quartz crystal oscillators. The series typically offers various frequencies and package options. Mercury Electronics has a long history in Taiwan's quartz crystal manufacturing industry, providing frequency control products since 1973. This specific model represents a standard XO variant within their portfolio.

Oscillators Replacement Considerations

Direct substitutes may include other 15.960 MHz LVCMOS oscillators in a 2.0x1.6mm SMD package from manufacturers like SiTime or Epson. Ensure replacement parts match the 1.8V supply voltage and pinout configuration. Verify that any alternative component supports the same operating temperature range and load capacitance specifications.
