Procurement Notes
Verify the specific frequency tolerance and load capacitance requirements against the system design specifications before procurement. Ensure the 1.8V supply rail stability meets the oscillator's operational limits. Confirm that the 4-SMD no-lead package dimensions align with the PCB footprint guidelines provided in the official datasheet to ensure proper soldering and mechanical reliability.
Selection Notes
Select this component when a precise 58.0 MHz clock source is required with low power consumption capabilities. The LVCMOS output is compatible with standard digital logic families operating at 1.8V. Consider the enable/disable feature if dynamic power management is necessary for the application. Verify thermal performance within the specified operating temperature range during selection.
Part Context
This part belongs to the 18QHTF21 series of surface-mount crystal oscillators from Mercury Electronics. The series offers various frequency options with consistent electrical characteristics and packaging. These oscillators are designed for high-reliability applications requiring stable frequency references in compact electronic devices.
Replacement Considerations
Direct replacements must match the 58.0 MHz frequency, 1.8V supply, LVCMOS output, and 4-SMD no-lead package. Verify pin compatibility and electrical parameters such as phase noise and jitter before substitution.
