3. Transmit max packet (three ports transmitting max size isochronous packet—4096 bytes, sent on every isochronous interval, s400,

data value of 0xCCCCCCCCh), VDD = 3.3 V, TA = 25°C

4. Repeat typical packet (one port receiving DV packets on every isochronous interval, two ports repeating the packet, s100), VDD =

3.3 V, TA = 25°C

5. Idle (three ports transmitting cycle starts), VDD = 3.3 V, TA = 25°C
