MK1412

MK1412 MPEG Audio Clock Synthesizer Description The MK1412 is the ideal way to generate clocks for MPEG audio devices in computers. The device uses ICS/MicroClock’s proprietary mixture of analog and digital Phase-Locked Loop (PLL) technology to synthesize one of eight frequencies (four on each output) from the 14.31818 MHz reference. In an 8 pin SOIC, the MK1412 can save component count, board space, and cost over crystals and oscillators, and increase reliability by eliminating three expensive mechanical devices from the board. We offer many other clocks for computers and computer peripherals. Consult us when you need to remove crystals and oscillators from your board. Due to a long lead time in the original wafer fab that makes the MK1412S, we have retooled the die and now call the part the MK1412A. All functional parameters are the same as or better than the original part. Features Packaged in 8 pin SOIC Input crystal or clock frequency of 14.31818 MHz Provides master MPEG clocks for 32 kHz, 44.1 kHz, 48 kHz and 96 kHz sampling rates Output clock frequencies of 256x and 512x of the audio sampling rates compatible with most DACs Low jitter Full CMOS output swing with 25mA drive capability at TTL levels 3.3V or 5V±10% supply voltage Advanced, low power CMOS process The A version is the newest version in a more advanced manufacturing process Block Diagram VDD GND 2 S1, S0 Output Buffer PLL Clock Synthesis and Control Circuitry ÷2 Output Buffer CLK 14.3...
