PRELIMINARY INFORMATION

MPEG Audio Clock Synthesizer

MK1413

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.

Features

2 VDD P Connect to +3.3V or +5V.
3 GND P Connect to ground.
4 NC - No Connect.
5 CLK O Audio Clock Output as per table above.
6 S1 I Frequency Select 1 Input. Determines CLK output as per table above.
7 S0 I Frequency Select 0 Input. Determines CLK output as per table above.
8 X2 O Crystal Connection to a 14.31818 MHz crystal, or leave unconnected for clock input.

Key: I = Input, O = output, P = power supply connection

External Components/Crystal Selection

A minimum number of external components are required for proper oscillation. For a crystal input, one
load capacitor should be connected to each of the X1 and X2 pins and ground, and a parallel resonant

14.31818 MHz crystal is recommended. The value (in pF) of each crystal load capacitor should equal
(CL-4)*2, where CL is the crystal’s load (correlation) capacitance in pF. The frequency tolerance of the

crystal should be 50ppm or better. For a clock input, connect to X1 and leave X2 unconnected. A
decoupling capacitor of 0.1µF should be connected between VDD and GND on pins 2 and 3, and 33Ω

terminating resistor may be used on the clock output if the trace is longer than 1 inch.
