Description
The MK1410 and MK1411 are the ideal way to generate clocks for NTSC/PAL video encoders and decoders. Stored in the devices are two or four popular frequencies for NTSC and PAL. In an 8 pin SOIC, the chips 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 20µA.
