NOTE Refer to the CAN Specification for calculations necessary to validate timing compliance. Jitter tolerance calculations must be performed to validate the implementation. Table 5-60 and Table 5-61 present Timing and Switching characteristics for DCAN and MCAN Interface. Table 5-60. Timing Requirements for CAN Receive NO. PARAMETER DESCRIPTION MIN NOM MAX UNIT f(baud) Maximum programmable baud rate 1 Mbps - td(CANnRX) Delay time, CANnRX pin to receive shift register 10 ns Table 5-61. Switching Characteristics Over Recommended Operating Conditions for CAN Transmit NO. PARAMETER DESCRIPTION MIN MAX UNIT f(baud) Maximum programmable baud rate 1 Mbps - td(CANnTX) Delay time, Transmit shift register to CANnTX pin(1) 10 ns (1) These values do not include rise/fall times of the output buffer. CAUTION The IO timings provided in this section are only valid if signals within a single IOSET are used. The IOSETs are defined in Table 5-62. In Table 5-62 are presented the specific groupings of signals (IOSET) for use with DCAN and MCAN. Table 5-62. DCAN and MCAN IOSETs SIGNALS IOSET1 IOSET2 IOSET3 IOSET4 BALL MUX BALL MUX BALL MUX BALL MUX DCAN1 dcan1_tx N5 0 D14 12 F14 12 dcan1_rx N6 0 D15 12 C14 12 MCAN mcan_tx W7 0 F13 12 F15 12 mcan_rx W6 0 E14 12 F16 12 5.9.6.14 GMAC_SW The two-port gigabit ethernet switch subsystem (GMAC_SW) provides ethernet packet communication and can be configured as an ethernet switch. It provides Reduced Gigabit Media Independent Interface (RGMII), and the Management Data Input/Output (MDIO) for physical layer device (PHY) management. NOTE For more information, see the Gigabit Ethernet Switch (GMAC_SW) section of the Device TRM. |
