This is a PDF file that contains a 56-pin pinout diagram, which introduces the function and usage of the V56 pin.
The Pericom PI6C110E is a clock solution device designed for 133 MHz Celeron and Pentium II/III processors. It integrates a dual PLL clock generator, an SDRAM buffer, and a PC interface. The device supports selectable CPU and SDRAM clocks, power-down functions, and spread spectrum modulation to minimize power consumption and EMI radiation.
