PRELIMINARY INFORMATION
MK1413
MPEG Audio Clock Synthesizer
Description
The MK1413 is the ideal way to generate clocks
for MPEG audio devices in computers. The device
uses MicroClock’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.
MicroClock offers many other clocks for
computers and computer peripherals. Consult
MicroClock when you need to remove crystals and
oscillators from your board.
