Overview
The 18QHTF21-50.2133-OE is a crystal oscillator manufactured by Mercury Electronic Ind. Co., Ltd. It operates at a frequency of 50.2133 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 2.0mm x 1.6mm. The component is designed for standard timing applications within specified operating temperature ranges.
Feature Summary
- Integrates LVCMOS output logic for digital signal compatibility
- Includes hardware enable/disable control functionality
- Utilizes a low-profile surface-mount package design
Applications
- General clock generation for electronic circuits
- Timing reference for digital systems
- Embedded system clock sources
Procurement Notes
Verify the specific frequency suffix matches the required 50.2133 MHz specification. Confirm the 1.8V supply voltage requirement aligns with the target circuit design. Ensure the 4-SMD no-lead package footprint is compatible with the PCB layout. Check datasheet details for operating temperature range constraints before integration.
Selection Notes
Select this component when a precise 50.2133 MHz clock source is required with low power consumption due to the 1.8V operation. The enable/disable feature allows for power management in battery-operated devices. Consider the small 2.0x1.6mm footprint for space-constrained designs requiring standard LVCMOS outputs.
Part Context
This part belongs to the Mercury Electronic 18QHTF21 series of surface-mount crystal oscillators. The series offers various frequencies and voltages. Mercury Electronic is a Taiwan-based manufacturer specializing in quartz crystals and timing components, established as a pioneer in the local industry since 1973.
Replacement Considerations
Direct substitutes must match the 50.2133 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD 2.0x1.6mm package. Verify pinout and enable logic compatibility. Cross-reference with other manufacturers offering identical electrical and mechanical specifications.
