18QHTF32-40.985-PD

Oscillators Overview

The 18QHTF32-40.985-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind., Co., Ltd. It operates at a fixed frequency of 40.985 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a standby or power-down mode capability. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise timing signals.

Oscillators Feature Summary

• LVCMOS output logic interface
• Integrated standby or power-down functionality
• Compact 4-SMD no-lead surface mount package

Oscillators Applications

• General purpose clock signal generation
• Digital circuit timing reference
• Embedded system clock sources

Oscillators Procurement Notes

Verify the specific datasheet for exact electrical parameters and pin configuration before integration. Confirm that the 1.8V supply voltage aligns with the target system design. Ensure the 4-SMD package footprint matches the PCB layout requirements. Check for any specific ordering suffixes that may alter performance characteristics.

Oscillators Selection Notes

Select this component when a 40.985 MHz clock source is required with low voltage operation. The LVCMOS output is compatible with standard digital logic families. Consider the power-down feature if energy efficiency during idle states is a priority. Verify temperature range specifications against the operating environment constraints.

Oscillators Part Context

This part belongs to the 18QHTF32 series of oscillators from Mercury Electronics. The series includes various frequencies such as 41 MHz and 49.6667 MHz.
