Comments / Signal routing
C1
Bulk Capacitor
C2
100nF, SMD Ceramic, Low ESR
Close (<5mm) to VSUP1, VSUP2 terminals with good ground return
C3
100nF, SMD Ceramic, Low ESR
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.
C4
4,7uF, SMD Ceramic, Low ESR
Bulk Capacitor
C5
V1⁽²⁾
L1⁽²⁾
180pF, SMD Ceramic, Low ESR
Varistor Type TDK AVR-M1608C270MBAAB
SMD Ferrite Bead Type TDK MMZ2012Y202B
Close (<5mm) to LIN terminal.
Total Capacitance on LIN has to be below 220pF.
(C_total = C_LIN-Terminal + C5 + C_Varistor ~ 10pF + 180pF + 15pF)
Optional (close to LIN connector)
Optional, (close to LIN connector)
Notes
1. 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.
2. Components are recommended to improve EMC and ESD performance.
