Overview
The 18QHTF21-6.176-OE is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd. It operates at a fixed frequency of 6.176 MHz and utilizes LVCMOS output logic. The device is powered by a single 1.8V supply voltage 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 x 1.6mm. The component is designed for industrial applications, supporting an operating temperature range from -40°C to 85°C. It complies with RoHS standards.
Feature Summary
- LVCMOS output logic interface
- Enable/Disable control functionality
- Industrial temperature range operation
- RoHS compliant construction
Applications
- General clock signal generation
- Digital circuit timing references
- Embedded system clock sources
- Industrial control modules
Procurement Notes
Verify the specific ordering suffix matches the required frequency and voltage specifications. Confirm that the 4-SMD no-lead package footprint aligns with the PCB layout design. Ensure the LVCMOS output level is compatible with the receiving logic inputs. Check for any specific handling requirements related to electrostatic discharge sensitivity during assembly processes.
Selection Notes
Select this component when a low-voltage 1.8V supply is available and a small form factor is required. The enable/disable feature makes it suitable for battery-powered or power-sensitive designs. Verify that the 6.176 MHz frequency meets the system timing requirements. Consider the industrial temperature rating if the application environment varies significantly.
Part Context
This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequencies and supply voltages. The 'OE' suffix typically indicates the enable/disable pin configuration. These components are designed to replace through-hole oscillators with smaller surface-mount alternatives.
Replacement Considerations
Direct replacements must match the 6.176 MHz frequency, 1.8V supply, LVCMOS output, and 2.0x1.6mm package. Verify pin compatibility for the enable function. Cross-reference with other manufacturers offering similar small-footprint XO devices.
