Pin Information (continued)
Power Supplies for ORT82G5
Power Supply Descriptions
Table 31 shows the ORT82G5 embedded core power supply connection groupings. The Tx-Rx digital power sup-
plies are used for transmit and receive digital logic including the microprocessor logic. The Tx-Rx analog power
supplies are used for high-speed analog circuitry between the I/O buffers and the digital logic. The Rx input buffer
power supplies are used to power the input (receive) buffers. The Tx output buffer supplies are used to power the
output (transmit) buffers. The Rx and Tx buffer power supplies can be independently set to 1.5 V or 1.8 V, depend-
ing on the end application. The auxiliary and guard band supplies are independent connection brought out to pins.
In the ORT82G5, many of the VDD pins shown in Table 31 are connected together at the package substrate level.
The same also applies for various VSS pins. At the package ball level in Table 33, the following names appear
instead of the names in Table 31: VDDT, VDDR, VDDOB, VDDIB, VSST, VSSRX.
