Overview
The 18QHTF21-8.960-PD is a standard crystal oscillator (XO) manufactured by Mercury Electronics Ind. Co. Ltd, operating at a frequency of 8.96 MHz. It utilizes LVCMOS output logic and supports a supply voltage of 1.8V. The device features a standby or power-down function for energy management. It is housed in a compact 4-SMD, No Lead package, suitable for surface-mount applications requiring precise clock synchronization.
Feature Summary
- LVCMOS output interface for digital circuit compatibility
- Integrated standby mode to reduce power consumption
- Compact 4-SMD no-lead surface mount packaging
Applications
- Clock signal generation for digital systems
- Synchronization circuits in communication devices
- Embedded system timing references
Procurement Notes
Verify the exact frequency tolerance and load capacitance requirements against your specific design specifications before procurement. Confirm that the 1.8V supply voltage aligns with your system's power rails. Ensure the 4-SMD package footprint matches your PCB layout constraints. Cross-reference the datasheet for any specific handling instructions related to the no-lead package type.
Selection Notes
Select this component when a low-voltage 1.8V operation is required alongside an 8.96 MHz reference frequency. The LVCMOS output is appropriate for standard digital logic levels. Consider the power-down feature if system efficiency is a priority. Verify that the 4-SMD form factor fits within the available board space compared to larger through-hole alternatives.
Part Context
Mercury Electronics Ind. Co. Ltd has been manufacturing frequency control products since 1973, establishing itself as a pioneer in the quartz industry in Taiwan. The company specializes in producing various oscillators including TCXOs, VCTCXOs, and standard XOs. This part belongs to their line of high-frequency LVCMOS oscillators designed for precise synchronization in electronic applications.
Replacement Considerations
Direct substitutes include other 8.96 MHz LVCMOS oscillators from Mercury Electronics such as the 18QHTF21-8.0004-PD or 18QHTF21-96.768-PD, provided the frequency difference is acceptable. Ensure any replacement maintains the 1.8V supply requirement and 4-SMD package dimensions for mechanical compatibility.
