18QHTF21-103.680-PD

Overview

The 18QHTF21-103.680-PD is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a frequency of 103.68 MHz and utilizes LVCMOS output logic. The device requires a supply voltage of 1.8V and features a standby (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.

Feature Summary

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

Applications

• General electronic timing circuits
• Digital signal processing systems
• Communication equipment requiring precise clock signals

Procurement Notes

Verify the specific ordering suffix to ensure compatibility with required frequency and package specifications. Confirm that the 1.8V supply voltage aligns with target system requirements. Check for any additional environmental or performance certifications if applicable to the end application.

Selection Notes

Select this component when a 103.68 MHz clock source is required with low power consumption. The small 2.0x1.6mm footprint makes it suitable for space-constrained designs. Ensure the LVCMOS output level matches the input requirements of the connected integrated circuit.

Part Context

This part belongs to the Mercury Electronics SMD oscillator series designed for surface mount applications. The 18QHTF21 prefix indicates a specific form factor and electrical characteristic set within their product line, distinct from other frequency options like 68.665 MHz or 96.768 MHz.

Replacement Considerations

Direct substitutes must match the 103.68 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pinout compatibility before replacement.
