I C R O C LOC K Description 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.
