ORCA ORT82G5 Data Sheet

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.
