The device requires a 1.8V supply voltage and features a standby mode for power down functionality. It is housed in a compact 4-SMD, No Lead package designed for surface mount technology.

Feature Summary

• Supports low voltage operation with 1.8V supply requirement
• Includes standby capability for power management
• Provides LVCMOS output signal compatibility

Applications

• General purpose clock generation
• Digital signal processing systems
• Communication equipment timing

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against your circuit design before procurement. Confirm that the 1.8V operating voltage aligns with your system's power rails. Ensure the 4-SMD no-lead package dimensions fit within your PCB footprint constraints. Check for any specific handling instructions regarding electrostatic discharge protection during assembly.

Selection Notes

Select this component when a precise 86.56 MHz clock source is required for LVCMOS compatible digital circuits. Consider the 1.8V supply constraint to ensure compatibility with low-power system architectures. Evaluate the need for standby functionality if power efficiency is a critical design parameter. Compare physical dimensions against available board space to confirm the 4-SMD package suitability.
