18QHTF21-76.200-PD

Overview

The 18QHTF21-76.200-PD is a crystal oscillator (XO) manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 76.2 MHz and utilizes LVCMOS output logic. 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 2.0 x 1.6 mm. This component is designed for timing applications requiring precise clock signals in space-constrained electronic systems.

Feature Summary

• Integrates LVCMOS output logic for standard digital interface compatibility
• Features a low-profile 4-SMD No Lead surface-mount package
• Supports standby mode to reduce power consumption during idle periods

Applications

• General purpose clock signal generation in embedded systems
• Timing reference for high-speed data communication interfaces
• Power-sensitive portable electronic devices requiring low profile components

Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to ensure correct voltage and output configuration. Confirm that the 4-SMD No Lead package matches the PCB footprint requirements. Check for any recent revisions to the pinout or electrical characteristics before finalizing the bill of materials.

Selection Notes

Select this component when a 76.2 MHz clock source with LVCMOS outputs is required in a minimal footprint. Ensure the system design accommodates the 1.8V supply rail and can utilize the power-down feature if power efficiency is a priority. Validate thermal performance within the specified operating temperature range for the target application environment.

Part Context
