18QHTF21-86.9375-PD

Overview

The 18QHTF21-86.9375-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronic Ind., Co., Ltd. It operates at a nominal frequency of 86.9375 MHz and utilizes LVCMOS output logic. The device is designed for a supply voltage of 1.8V and features a standby or power-down control function to manage power consumption. It is housed in a compact 4-SMD, no-lead package with dimensions of 2.0mm x 1.6mm. This component is suitable for applications requiring precise clock signals in space-constrained electronic designs.

Feature Summary

• Supports LVCMOS output logic for digital interface compatibility
• Includes standby or power-down functionality for energy management
• Utilizes a small form factor 4-SMD no-lead package

Applications

• General purpose clock signal generation
• Digital circuit timing references
• Embedded systems requiring low-power oscillators

Procurement Notes

Verify the specific datasheet for the 18QHTF21-86.9375-PD to confirm electrical parameters such as frequency stability, load capacitance, and operating temperature range before integration. Ensure that the 1.8V supply voltage aligns with your system design requirements. Check for any specific handling instructions related to the SMD package during assembly processes.

Selection Notes

Select this oscillator when a standard LVCMOS clock source is required at 86.9375 MHz with a 1.8V supply. Consider the 2.0x1.6mm footprint for PCB layout constraints. The power-down feature makes it suitable for battery-operated devices where standby current reduction is critical. Compare against other Mercury Electronics models if different frequencies or package sizes are needed.

Part Context

This part belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronic Ind., Co., Ltd. The series offers various frequencies and package options. The 'PD' suffix typically indicates the presence of a power-down or standby control pin. Mercury Electronics specializes in quartz crystals and frequency control products, providing solutions for telecommunications and consumer electronics.

Replacement Considerations

Direct replacements must match the 86.9375 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility, especially the power-down control pin. Other Mercury Electronics parts like 18QHTF21-68.080-PD share similar packages but differ in frequency.
