Oscillators Procurement Notes

Verify the specific frequency tolerance and load capacitance requirements against the target circuit design before procurement. Confirm that the 1.8V supply voltage aligns with the system power rails. Ensure the 4-SMD footprint matches the PCB layout constraints. Check for any specific RoHS or environmental compliance certifications required by the end product regulations. Validate the operating temperature range suitability for the intended application environment.

Oscillators Selection Notes

Select this oscillator when a precise 23.587 MHz reference is required with low power consumption. The LVCMOS output ensures compatibility with standard logic families. Consider the 1.8V operation if the system benefits from lower voltage domains. The small form factor suits space-constrained designs. Evaluate the standby feature if power management during idle states is critical for the application efficiency.
