MK3230 Overview
The MK3230 is the smallest size, lowest power system clock synthesizer available. It is the ideal way to generate clocks for portable puters, PDAs, and other devices where low power is required. Using analog Phase-Locked Loop (PLL) techniques, the device operates from a single 32.768 kHz crystal to produce the 32.768kHz, CPU, system, keyboard controller, and floppy (or super I/O) controller output clocks.
