Overview
The 18QHTF21-75.8875-OE is a standard crystal oscillator manufactured by Mercury Electronics Ind. Co., Ltd. It operates at a fixed frequency of 75.8875 MHz and utilizes LVCMOS output logic. The device requires a supply voltage of 1.8V and features an enable/disable control function. It is housed in a compact 4-SMD, No Lead package with dimensions of 2.0 x 1.6 mm.
Feature Summary
- Integrates enable and disable functionality for power management
- Utilizes LVCMOS output logic for digital interface compatibility
- Designed in a small surface-mount package for space-constrained applications
Applications
- Digital signal processing systems requiring precise clocking
- Communication equipment utilizing standard frequency references
- Embedded systems with low-voltage logic requirements
Procurement Notes
Verify the specific suffix OE against official Mercury Electronics documentation to confirm availability and exact electrical tolerances. Ensure the 1.8V supply requirement aligns with target system design. Confirm package dimensions match PCB footprint specifications before finalizing procurement orders.
Selection Notes
Select this component when a 75.8875 MHz reference is required with LVCMOS outputs. The 1.8V operating voltage dictates compatibility with low-power digital circuits. The enable pin allows for dynamic power control, making it suitable for battery-operated or energy-efficient designs requiring active clock management.
Part Context
This model belongs to the 18QHTF21 series of standard oscillators from Mercury Electronics. The series typically offers various frequency options within a consistent 2.0x1.6mm SMD form factor. The part number indicates a specific frequency variant within this standardized product line.
Replacement Considerations
Direct substitutes must match the 75.8875 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pinout compatibility and thermal characteristics before integrating alternative sources into existing designs.
