• Provides stable clock signals via LVCMOS output interface
• Supports low voltage operation at 1.8V
• Includes standby and power-down functionality for energy management

Applications

• Applications requiring stable clock signals at low voltage
• General electronic systems utilizing standard XO components

Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the official datasheet before procurement. Confirm that the 1.8V supply voltage aligns with the target system design. Ensure the 4-SMD No Lead package dimensions fit the intended PCB footprint. Cross-reference the part number suffix to confirm the exact frequency specification matches the project needs.

Selection Notes

Select this component when a 58 MHz clock signal is required with LVCMOS compatibility. Consider the 1.8V operating voltage constraint during system architecture planning. Evaluate the need for standby capabilities if power efficiency is a priority. Verify that the surface-mount package type suits the assembly process and space constraints of the final product.

Part Context

This model belongs to the 18QHTF21 series of crystal oscillators from Mercury Electronics. The series typically offers various frequencies within the standard range, all sharing similar electrical characteristics and packaging. The 'PD' suffix likely indicates specific packaging or processing details consistent with the manufacturer's lineup.

Replacement Considerations

Direct substitutes may include other 58 MHz LVCMOS oscillators in a 4-SMD No Lead package. Ensure replacement parts match the 1.8V supply voltage and pin configuration. Verify that alternative sources provide equivalent stability and phase noise specifications for the application.
