SM8703CV
FUNCTIONAL DESCRIPTION
27MHz Master Clock
The 27MHz master clock is generated either by connecting a crystal oscillator element between XTI (pin 8)
and XTO (pin 9), as shown in figure 1, or by connecting an external 27MHz clock to XTI, as shown in figure 2.
The crystal oscillator element must be used in fundamental frequency mode.
