The MPC9315 is a 2.5 V and 3.3 V compatible, PLL based clock generator designed for low-skew clock distribution in low-voltage mid-range to high-performance telecom, networking and computing applications. The MPC9315 offers 8 low-skew outputs and 2 selectable inputs for clock redundancy. The outputs are configurable and support 1:1, 2:1, 4:1, 1:2 and 1:4 output to input frequency ratios. In addition, a selectable output 180° phase control supports advanced clocking schemes with inverted clock signals. The MPC9315 is specified for the extended temperature range of -40 to +85°C.
