Electrical and Thermal Characteristics
3.2 AC Electrical Characteristics
This section provides the AC electrical characteristics for the 750CL. After fabrication, parts are sorted by
conformance to the AC specifications for that frequency. The processor core frequency is determined 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. For each part number, maximum power is measured at nominal VDD and at the indicated TJ and frequency, 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.
3. For each part number, typical power is an estimate of the average value modeled for process parameter parts in a system execut-
ing typical applications at the indicated nominal VDD, frequency, and TJ. Note that typical power cannot be used in the design of the
power supply or cooling system.
4. Previous IBM PowerPC processors specified the power dissipation of the processor without regard to the part number. In contrast,
the 750CL power dissipation specification is specific to a particular part number. Each power specification is specific to four condi-
tions: processor part number, processor actual operating frequency, processor actual junction temperature, and processor actual
VDD.
5. Information on derating the power dissipation of the 750CL over temperature is expected to be available in the second quarter of
2007. Contact ppcsupp@us.ibm.com for information.
