Description

The SL28EB742 is a high-performance clock generator supporting Intel Cedarview platforms. The SL28EB742 is rated to

support extended grade temperature. Utilizing an inexpensive 14.318 MHz crystal, it is capable of supporting multiple

frequencies from four PLLs. The CPU clock can support a frequency range from 83.33 to 166 MHz by configuration of two strap

achieve optimum compliance and clock signal integrity; historically, attainable typically through device and/or board redesigns.
