18QHTF21-103.615-PD

Overview

The 18QHTF21-103.615-PD is a quartz crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. This component operates at a frequency of 103.615 MHz and utilizes LVCMOS output logic. It supports a supply voltage range that includes 1.8V operation with standby power-down functionality. The device is housed in a compact 4-SMD, No Lead package, designed for surface-mount applications requiring precise timing signals in electronic circuits.

Feature Summary

• Supports LVCMOS output logic for standard digital interfacing
• Features standby (power down) capability to reduce consumption
• Utilizes quartz crystal technology for stable frequency generation

Applications

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

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your design specifications before procurement. Confirm that the 4-SMD no-lead package dimensions align with your PCB footprint constraints. Ensure the selected supply voltage matches the operational requirements of your target circuit interface.

Selection Notes

Select this model when a 103.615 MHz clock source is required with low-profile surface-mount packaging. Consider the LVCMOS output compatibility with your downstream logic family. Evaluate the need for standby functionality if power management is a critical design constraint for the application environment.

Part Context

This part belongs to the 18QHTF21 series of SMD oscillators from Mercury Electronics. The series offers various frequencies and voltage options within a standardized small outline package. It serves as a timing reference component for systems requiring reliable quartz-based frequency stability in consumer or industrial electronics.

Replacement Considerations

Direct substitutes must match the 103.615 MHz frequency, LVCMOS output, and 4-SMD package. Verify pinout compatibility and electrical characteristics such as drive strength and rise/fall times before substitution.
