AM3359: RGMII Transition time, RD and RX_CTL

-DK--san,

Thank you for your reply.

Table 7-19 is Timing Requirements, not Switching Characteristics. The maximum transition time for the input signals of RD and RX_CTL should be provided in data manuals.

For the transition time for RD and RX_CTL, do the input conditions in Table 7-7 apply to?

If not so, when the setup and hold requirements are met, are the transition time requirements which are not provided in data manuals also met?

Best regards,

Daisuke

Hi -DK--san,

I understand that the transition time requirements which are NOT provided in data manuals are met when the setup and hold requirements are met.

Is my understanding correct?

-DK--san,

I understand the transition time for RD and RX_CTL as follows:

For 10 Mbps, when the pulse duration for RXC is 240ns the transition time of 238ns is allowed for RD and RX_CTL.

For 100 Mbps, when the pulse duration for RXC is 24ns the transition time of 22ns is allowed for RD and RX_CTL.

For 1000 Mbps, when the pulse duration for RXC is 4.4ns the transition time of 2.4ns is allowed for RD and RX_CTL.

Is my understanding correct?

Hi -DK--san,

I'm sorry to many times.

Should all signals in EMAC meet the conditions in table 7-7 except when specified otherwise?

-DK--san,

I'm sorry to many times.

For AM437x, the transition time for RD and RX_CTL is NOT removed from Table 5-34 on the latest datasheet (SPRS851E).

Why was it removed for AM335x?
