MK1412A中文资料ICST数据手册PDF规格书

描述 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.
