Oscillators Procurement Notes

Verify the specific ordering suffix to ensure the correct package variant and tolerance level match the design requirements. Confirm that the 3.3V supply voltage aligns with the target system's power rails. Ensure the 2mm x 1.6mm footprint dimensions are compatible with the PCB layout constraints. Check for RoHS compliance status if environmental regulations apply to the final product assembly.

Oscillators Selection Notes

Select this component when a low-profile, cost-effective clock solution is required for 25 MHz applications. The LVCMOS output is suitable for direct interfacing with standard CMOS logic families without additional buffering in many cases. Consider the +/- 50 ppm stability specification against the system's jitter and phase noise requirements. The enable pin allows for dynamic power saving during idle states.

Oscillators Part Context

This part belongs to the ISA11 series of surface-mount oscillators from ILSI America. The series offers various frequencies and packages, with the ISA11 specifically denoting the 2mm x 1.6mm form factor. It serves as a fundamental timing element in consumer electronics and industrial control systems where size and power efficiency are critical design factors.

Oscillators Replacement Considerations

Direct replacements must match the 25 MHz frequency, LVCMOS output type, 3.3V supply, and 2x1.6mm package dimensions. Verify equivalent stability and load current specifications. Cross-reference pinouts to ensure compatibility with existing PCB footprints.
