1. For A-stepping (400-MHz) IXP2400, VCC1.3 and VCCA1.3 is 1.3V.
1. Typical values are based on a full-duplex 2G Ethernet design with one QDR channel
The measurements shown in
forwarding + QoS) at OC-48 line rate with worst-case minimum size 48-byte packets.
1. Values presented include core and I/O.
2. 400-MHz (B Stepping) IXP2400 devices should use a 1.1V core power supply; 600-MHz IXP2400
3. QDR and DDR I/O values include power consumption from termination.
The values in
taken by running synthetic tests that maximize the activity factors for a particular power supply
rail, one rail at a time, and are expected to reflect the worst-case power consumption for each power
supply rail under artificial conditions.
