General Description

The MK3235 is the smallest size, lowest power system clock synthesizer available.

It is the ideal way to generate clocks for handheld computers, such as PDAs, PICs, 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, 14.318MHz, and serial communications output clocks.
