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.

MicroClock offers many other clocks for

computers and computer peripherals. Consult

MicroClock when you need to remove crystals and

oscillators from your board.
