ICS9112-06/07

Application Suggestion:

ICS9112 is a mixed analog/digital product. The analog portion of the PLL is very sensitive to any random noise generated by

charging or discharging of internal or external capacitor on the power supply pins. This type of noise will cause excess jitter

to the outputs of ICS9112. Below is a recommended lay out to alleviate any addition noise. Figure below depicts only ICS9112-

07, but similar techniques could be used for dash 06. For additional information on FT. layout, please refer to our AN07. The

0.1 uF capacitors should be connected as close as possible to power pins (4 & 13). An Isolated power plane with a 2.2 uF

capacitor to ground will enhance the power line stability.
