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.

Features

• Input crystal frequency of 32.768 kHz

• Lowest power solution available

• Lowest profile clock solution where height is critical

• Output clock frequencies up to 50 MHz

• Three output clocks

• 3.3V or 5.0V operation

• Duty cycle of 45/55

• Eight selectable CPU frequencies

• CPU clock power down

• Separate battery supply pin for 32 kHz runs to 2V

• IDD less than 4µA when 32 kHz running

• Packaged in 16 pin narrow (0.150”) SOIC
