MPEG Audio Clock Synthesizer Integrated Circuit Systems, Inc.•525 Race Street•San Jose•CA•95126•(408)295-9800tel•www.icst.com PRELIMINARY INFORMATION 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. Block Diagram Description Features

Connect to a 14.31818 MHz crystal or clock. 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. Pin Descriptions Key: I = Input, O = output, P = power supply connection Pin Assignment 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 C L 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 33 Ω terminating resistor may be used on the clock output if the trace is longer than 1 inch. 1 8 GND VDD CLK 8 pin SOIC NC S1 S0 Audio Clock Accuracy pin 6 pin 7 pin 5 (ppm) 0 0 8.192 MHz -2 ppm 0 1 11.2896 MHz -24 ppm 1 0 12.288 MHz -2 ppm 1 1 16.9344 MHz -24 ppm Audio Clock Output Select Table
