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 MK3.

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. The extremely low IDD, the ease of surface mounting, the upgradeability of CPU frequencies, and the power down capability are added benefits in using the part. MK3233 Handheld System Clock Synthesizer Features • Input crystal frequency of 32.768 kHz • Lowest power solution available • Operating temperature of -20 to 70 °C • Output clock frequencies up to 50 MHz • Three output clocks • 3.3 V or 5.0 V operation • Duty cycle of 45/55 • Eight selectable CPU frequencies • CPU or Communication clock power down • Separate battery supply pin for 32 kHz runs to 2V • IDD less than 4µA when 32 kHz running • Serial port clocks of 1.8432 MHz (-01 version) or 3.6864 MHz (-02 version) • Packaged in 16 pin narrow SOIC Block Diagram VDD GND CPUS0 CPUS1 CPUS2 PDCPU CPU Clock Synthesis and Control Circuitry Output Buffer CPUCLK PDCOMM PD VDD32 32.768 kH.
