MK2731-04C

PRELIMINARY INFORMATION MK2731-04C MPEG Audio Clock Description The MK2731-04 is a low cost, low jitter, high performance clock synthesizer designed to replace expensive discrete clock oscillators in MPEG audio applications. Using ICS/MicroClock’s patented analog/digital Phase-Locked Loop (PLL) techniques, the device uses an inexpensive 14.4 MHz crystal input to produce all of the popular audio sampling frequencies. ICS manufactures the largest variety of Set-Top Box and multimedia clock synthesizers for all applications. Consult ICS to eliminate VCXOs, crystals and oscillators from your board. Features Packaged in 16 pin narrow SOIC Replaces multiple oscillators 3.3V or 5V operation Uses an inexpensive 14.4 MHz crystal Supports 32 kHz, 44.1 kHz, 48 kHz, and 96 kHz audio sampling rates Has 256x, 384x, and 512x sampling rates compatible with every popular audio DAC Zero ppm synthesis error 25 mA output drive capability at TTL levels Advanced, low power, sub-micron CMOS process Block Diagram VDD 3 3 GND 3 S2:S0 X1 14.40 MHz crystal X2 Crystal Oscillator PLL/Clock Synthesis Circuitry ÷2 Output Buffer Output Buffer CLK2 CLK1 MDS 2731-04 CA 1 Revision 122799 Printed 11/16/00 Integrated Circuit Systems, Inc. 525 Race Street San Jose CA 95126 (408)295-9800tel www.icst.com PRELIMINARY INFORMATION MK2731-04C MPEG Audio Clock Pin Assignment Output Clocks Select Table (MHz) 16 15 14 13 12 11 10 9 DC DC S0 S1 DC CLK2 VDD CLK1 S2 Pin 8 0 0...
