描述
The MK2712 is the ideal way to generate clocks for NTSC/PAL video encoders and decoders. Stored in the device are two sets of popular frequencies for NTSC and PAL. In an 8 pin SOIC, the chip can save component count, board space, and cost over surface mount crystals and oscillators, and increase reliability by eliminating one or two mechanical devices from the board. The power down pin turns off the device, drawing less than 20?A. ICS/MicroClock offers many other clocks for computers and computer peripherals. Consult us when you need to remove crystals and oscillators from your board.
