Crystal
The quartz crystal is strongly recommended as a low cost and high performance choice with the
82563EB/82564EB device. Quartz crystals are the mainstay of frequency control components and
are available from numerous vendors in many package types with various specification options
If using an external oscillator to provide a clock to the 82563EB/82564EB, the connection shown
in
connected. The XTAL1 input receives the output of the oscillator directly; AC coupling is not
recommended.
