for the DC and AC characteristics. The serial port consists of TXD, RXD, which are asynchronous
relative to any device outside the IXP2400.
1. All voltages referenced to Vss (GND).
2. AC load current is higher than the shown DC values.
3. For Cload greater than 20 pF or three or more devices, transceivers or clock buffers need to be used.
