The MK3234 is the smallest size, lowest power system
clock synthesizer available. It is the ideal way to
generate clocks for portable computers 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, and ISA bus (system) output
clocks.
The device has an individual power down pin for the
CPU clock, and a power down pin for the entire device.
The MK3234 can save board space and cost even if it
only replaces the 32kHz 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.
