Hello TI support team,
We are using SoC AM62Q with an external Quartz @25MHz
Customer is requesting a CAN FD with :
- Baud rate @ 2 Mbits/s
- Tolerance of bus speed (Crystal Tolerance) : +/- 0.30 % (Operating and component life)
- Bit time = 500 ns Typ +/- 0.30% (incl. aging)
- Number of time Quanta : Min = 8 / Max = 40 => Must use 20, 40 or 80 MHz clock
- Number of samples per bit = 1 (Single simple mode)
- Nominal sample point position : Min = 0.75 / Max = 0.80 ( 75% - 80% of bit time )
My concern is can we get a CAN_FD 2 @Mbits/s using an external Quartz @25MHz ... ?
Datasheet is referring to FCLK to drive CAN FD : as we need an accurate oscillator I guess PLL clock is not recommended due to jitter to generate @20MHz clock for CAN FD 2 Mbits/s ?
Thanks for your support
