The MPC970 was designed specifically to drive today's PowerPC 601 and Pentium processors while providing the necessary performance to address higher frequency PowerPC 601 as well as PowerPC 603 and PowerPC 604 applications. The 2x_PCLK output can toggle at up to 250MHz while the remaining outputs can be configured to drive the other system clocks for MPC 601 based systems. As the processor based clock speeds increase the processor bus will likely run at one third or FA SUFFIX
