TCAN1145-Q1: Schematic and Layout Review request for HKMC CCIC POIP Headunit

Hi Kenneth,

The schematics for both devices look good.

• Bus capacitors included - ensure placement close to connector and along signal path.
• Decoupling capacitors included and valued appropriately.
• Split capacitor included and valued appropriately.
• TVS diode included - ensure placement close to connector and along signal path. 
• Termination resistors included correctly and valued appropriately.
• CMC/Inductance placed nominally between transceiver and termination.
• All pull-up / series resistances are acceptable.

If possible to modify the CAN trace on TCAN1057, try to keeping signal traces close to the same length, and keep the number of left-turns and right-turns even to reduce length mismatch.

Regards,

Sean
