18QHTF21-20.0036-PD

Oscillators Overview

The 18QHTF21-20.0036-PD is a crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 20.0036 MHz and utilizes LVCMOS output logic levels. 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 2.0x1.6 mm.

Oscillators Feature Summary

• Supports low-voltage operation at 1.8V
• Includes standby mode capability
• Utilizes LVCMOS output interface

Oscillators Applications

• Digital signal processing systems
• Communication equipment requiring precise timing
• Embedded control circuits

Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD no-lead package footprint matches your PCB layout specifications to guarantee proper soldering and mechanical stability during assembly.

Oscillators Selection Notes

Select this component when a stable 20.0036 MHz clock source is required in space-constrained designs. The choice is driven by the need for low-power consumption due to the 1.8V operation and standby feature. Consider the small 2.0x1.6 mm package size if board real estate is limited compared to larger oscillator packages.
