The AV9107C-11 offers a tiny footprint solution for generating a fixed system clock and a selectable CPU clock. The 16 selectable CPU frequencies provide all necessary clocks for 386, 486 and Pentium systems.
In addition, the AV9107C-11 has one pin that, when forced low, will slow the CPU clock to 8 MHz. This feature is important in systems that have dynamic microprocessors. Dynamic microprocessors have a minimum operating speed, typically 8 MHz. In"green" PCs, the designer often wants to slow the CPU to its minimum operating speed to save power. The AV9107C-11 will smoothly slow the CPU to 8 MHz when the SLOWCLK pin goes low.
The AV9107C-11 is fabricated using 0.8m CMOS technology. As a result, a 45/55 duty cycle can be achieved on the CPU clock and ±250ps worst case absolute jitter.
