Procurement Notes

Verify the specific suffix 'I2' against the official Microchip datasheet to confirm package dimensions and pinout compatibility. Ensure the selected variant matches the required operating temperature range and supply voltage specifications for your design. Confirm that the blank programming state aligns with your production workflow for enabling the oscillator. Cross-reference the RoHS compliance status with current environmental regulations applicable to your region.

Selection Notes

Select this component when a small form factor and high-frequency stability are critical. The HCSL output is ideal for reducing noise in sensitive analog circuits. Consider the standby feature if power efficiency is a priority. Verify that the 4-pin package fits your PCB layout constraints. Ensure the programming tool or method is available for configuring the blank device before integration.
