18QHTF21-75.735-OE

Overview

The 18QHTF21-75.735-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 75.735 MHz and utilizes LVCMOS output logic. The device requires a supply voltage of 1.8V and features an enable/disable control function for power management. It is housed in a compact 4-SMD, no-lead package with dimensions of 2.0mm by 1.6mm. This component is designed for timing applications requiring precise clock signals within the specified operating temperature range.

Feature Summary

• LVCMOS output logic for digital interface compatibility
• Integrated enable/disable control functionality
• Compact 4-SMD no-lead surface mount package

Applications

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

Procurement Notes

Verify the specific ordering suffix to ensure the correct frequency and package variant matches the design requirements. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Check the enable pin configuration against the schematic to ensure proper control logic integration. Ensure the operating temperature range meets the environmental specifications of the final application.

Selection Notes

Select this oscillator when a 75.735 MHz clock source is required with low voltage operation. The LVCMOS output is suitable for standard digital logic families. Consider the small footprint for space-constrained designs. Verify that the enable feature supports the system's power sequencing needs. Ensure the package type is compatible with the PCB assembly process.

Part Context

This part belongs to the 18QHTF21 series of standard crystal oscillators from Mercury Electronics. The series offers various frequencies and supply voltages. The 'OE' suffix typically indicates the presence of an enable pin. Mercury Electronics specializes in quartz crystals and timing components, providing solutions for consumer electronics and industrial applications.

Replacement Considerations

Direct substitutes must match the 75.735 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout compatibility, specifically the enable pin location. Cross-reference with other manufacturers offering similar SMD oscillators if availability is an issue.
