MK3233 Overview
The MK3233 is the smallest size, lowest power system clock synthesizer available. It is the ideal way to generate clocks for smart cell phones, 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 32.768 kHz, CPU, and serial munications output clocks.
