NOTES:

2. Transmit maximum packet (all ports transmitting maximum size isochronous packet – 4096 bytes, sent on every isochronous

interval, S400, data value of CCCCCCCCh), VDD = 3.3 V, TA = 25°C.

3. Repeat typical packet (receiving on one port DV packets on every isochronous interval, S100, and transmitting on the other port),

VDD = 3.3 V, TA = 25°C.

4. Idle (one port receiving and one port transmitting cycle starts), VDD = 3.3 V, TA = 25°C.
