Oscillators Procurement Notes

Verify the specific frequency tolerance and stability requirements against the application needs before procurement. Confirm that the 3.3V supply voltage aligns with the target circuit design. Ensure the 4-SMD package footprint matches the PCB layout constraints. Check for RoHS compliance documentation if required by regulatory standards. Validate the enable/disable pin configuration with the host controller interface.

Oscillators Selection Notes

Select this component when a precise 33.333 MHz clock signal is required for digital interfaces. The CMOS output level ensures compatibility with standard logic families without additional buffering. The small form factor suits space-constrained designs. Consider the enable/disable feature if dynamic power management is necessary. Verify thermal performance within the specified operating temperature range.

Oscillators Part Context

This part belongs to the ISM95 series of ceramic SMD oscillators from ILSI. The series offers various frequencies and package sizes, providing flexibility for different timing applications. The ISM95 series is characterized by low jitter and non-PLL-based output, ensuring clean clock signals for high-speed data transmission and synchronization tasks in telecommunications and computing equipment.

Oscillators Replacement Considerations

Direct substitutes include other ISM95 series parts with identical frequency and package, such as ISM95-3251AH-25.000MHZ or ISM95-3251AH-27.000MHZ, provided the frequency difference is acceptable. Cross-brand replacements require matching frequency, voltage, package, and output logic specifications.
