Power Supplies for ORSO82G5
Power Supply Descriptions
In the ORSO82G5 embedded core the TX-RX digital power supplies 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, depending on the end application. The auxiliary
and guard band supplies are independent connection brought out to pins.
In the ORSO82G5, many of the VDD pads are connected together at the package substrate level and not individu-
ally connected to external pins. The same also applies for the VSS pads. Table 34. shows the package connections
to the common VSS and VDD groupings.
