levels. The high gain differential amplifier accepts peak-to-peak
input voltages as small as 150mV, as long as the common mode
voltage is within the specified minimum and maximum range.
Guaranteed output and part-to-part skew characteristics make
the ICS853S12I ideal for those clock distribution applications
demanding well defined performance and repeatability.
