Overview
The 18QHTF21-88.750-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 88.75 MHz and utilizes LVCMOS output logic levels. The device is designed for low-power applications, requiring a supply voltage of 1.8V. It features an enable/disable control function to manage power consumption during inactive periods. The component is housed in a compact 4-SMD, No Lead package with dimensions of 2.0mm x 1.6mm, suitable for surface-mount assembly on printed circuit boards.
Feature Summary
- LVCMOS output logic for digital interface compatibility
- Integrated enable/disable pin for power management
- Compact 4-SMD no-lead surface mount package
Applications
- Portable electronic devices requiring low power consumption
- Embedded systems utilizing LVCMOS interfaces
- Communication modules needing precise timing signals
Procurement Notes
Verify the specific suffix 'OE' matches the required enable/disable functionality and LVCMOS output type. Confirm that the 1.8V supply voltage aligns with the target system's power rails. Ensure the 2.0x1.6mm footprint is compatible with the PCB layout. Check for any specific temperature range requirements if operating in extreme environments.
Selection Notes
Select this component when a low-voltage 1.8V operation is mandatory for the design. The LVCMOS output is appropriate for direct connection to standard digital logic inputs without additional level shifting. The enable feature is critical for battery-operated applications where power efficiency is a primary constraint. Consider the small form factor for space-constrained designs.
Part Context
This part belongs to the QHTF series of crystal oscillators from Mercury Electronics. The series offers various frequencies and voltages. The '18' prefix indicates the 1.8V supply requirement. The 'F21' likely denotes the package style or series variant. This specific model provides a stable clock source for digital circuits requiring minimal current draw.
Replacement Considerations
Direct replacements must match the 88.75 MHz frequency, 1.8V supply, and LVCMOS output. Packages of identical 2.0x1.6mm dimensions are preferred for board compatibility. Verify that substitute parts also include the enable/disable control feature if power management is required in the application.
