Notes:

1. Stresses beyond those listed under Absolute Maximum Ratings could cause permanent damage to the device. Prolonged exposure

to levels above the operating limits but below the Absolute Maximums may affect device reliability.

2. Typical values are at 25°C.

Application Note

The MK1410/11 is commonly used to drive an AD722/4 NTSC/PAL encoder. If the encoder is not

displaying the proper color, this means that the input frequency to the MK1410/11 is incorrect. This is

caused by using the wrong type of crystal, or by connecting incorrect capacitors to X1 and X2. To get

correct color, specify the crystal as listed on page 2. The MK1410/11 has internal crystal capacitors set for a

crystal with 18 pF load capacitance. Contact MicroClock if unable to obtain the listed crystal.
