Freescale does not assume liability, endorse, or want components from external manufactures that are referenced in circuit drawings
or tables. While Freescale offers component recommendations in this configuration, it is the customer’s responsibility to validate their
application.
Components are recommended to improve EMC and ESD performance.

Close to VSUP terminals with good ground return
Close (<3mm) to digital supply terminals (EVDD, EVSS) with good
ground return.
The positive analog (VREFH/ VDDA) and the digital (EVDD) supply
should be connected right at the C3.
Bulk Capacitor
Close (<5mm) to LIN terminal.
Total Capacitance on LIN has to be below 220pF.
