MK1413

REV G 051310

Description

The MK1413 is the ideal way to generate clocks for MPEG

audio devices in computers. The device uses IDT’s

proprietary mixture of analog and digital Phase-Locked

Loop (PLL) technology to synthesize one of four frequencies

from the 14.31818 MHz reference. In an 8-pin SOIC, the

MK1413 can save component count, board space, and cost

over crystals and oscillators, and increase reliability by

eliminating three expensive mechanical devices from the

board.

IDT offers many other clocks for computers and computer

peripherals. Consult IDT when you need to remove crystals

and oscillators from your board.
