PRODUCTION DATA
These pins are used for a crystal oscillator. The OSC1 pin can also be used as a single-ended clock input from the microprocessor or some other clock source. See Section 9.1 section for further information on the functions of these pins. It is recommended to provide a 40 MHz crystal or CLKIN to support CAN FD data rates.
If using a crystal oscillator rather than a single-ended clock, much care must be taken when choosing the correct load capacitance and dampening resistor values. Please see the TCAN455x Clock Optimization and Design Guidelines application note for a full, detailed design procedure on the crystal oscillator choice and component decisions.
