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.
