3.2 AC Electrical Characteristics
This section provides the AC electrical characteristics for the 750GX. After fabrication, parts are sorted by
maximum processor core frequency as shown in Section 3.3, Clock AC Specifications, on page 18, and
tested for conformance to the AC specifications for that frequency. The processor core frequency is deter-
mined by the bus (SYSCLK) frequency and the settings of the PLL configuration (PLL_CFG[0-4]) signals.

Notes:
1. These values apply for all valid 60× buses. The values do not include I/O supply power (OVDD) or PLL supply power (AVDD). OVDD
power is system dependent, but is typically less than 2% of VDD power.
2. Maximum power is measured at the indicated VDD and TJ using parts with worst-case process parameters and running RC5-72.
RC5-72 runs hotter than typical production code, but it is possible to design code that runs even hotter than RC5-72. See Reducing
PowerPC 750GX Power Dissipation Application Note for more information.
3. Typical power is an estimate of the average value modeled in a system executing typical applications with VDD and typical process
parameters. Note that typical power cannot be used in the design of the power supply or cooling system.
