18QHTF21-64.9375-PD

Overview

The 18QHTF21-64.9375-PD is a crystal oscillator (XO) manufactured by Mercury Electronic Ind., Co., Ltd. It operates at a nominal frequency of 64.9375 MHz with an LVCMOS output logic level. The device requires a supply voltage of 1.8V and supports a standby or power-down function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm. This component is designed for timing applications requiring precise clock signals in space-constrained electronic systems.

Feature Summary

• Supports low-voltage operation at 1.8V for energy-efficient designs
• Includes standby mode capability to reduce power consumption during idle periods
• Utilizes a small surface-mount package suitable for high-density PCB layouts

Applications

• General-purpose digital circuit timing
• Embedded system clock generation
• Consumer electronics requiring precise frequency control

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before procurement. Ensure that the 1.8V supply voltage aligns with your system's power rails. Confirm that the LVCMOS output compatibility matches the input requirements of the connected logic devices. Check for any specific handling instructions regarding the no-lead SMD package to prevent damage during assembly.

Selection Notes

Select this component when a 64.9375 MHz clock signal is required with low power consumption constraints. The 1.8V operating voltage makes it suitable for modern low-voltage digital circuits. Consider the 2.0x1.6mm footprint if board space is limited. Ensure the LVCMOS output interface is compatible with the downstream components in the signal chain.

Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronic Ind., Co., Ltd. The series offers various frequencies within a standardized small form factor. These oscillators are commonly used in applications where stable timing references are critical, such as in communication modules and data processing units.

Replacement Considerations

Direct replacements must match the 64.9375 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD No Lead package dimensions. Verify that substitute parts meet the same electrical characteristics and thermal performance standards.
