I C R O C LOC K Description 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 communications output clocks. The device has multiple power down modes for the CPU, communications, and 32.768 kHz clocks. The MK3233 can save board space and cost even if it only replaces the 32 kHz oscillator circuitry and one additional surface mount crystal or oscillator.
