Note: To obtain the expected values of BL or FCL at any other XTAL frequency, use the following
formula shown in Equation
Example : For XGA75 at 24.576 MHz XTAL:
BL = 3824 * 24.576/28.63636 ≈ 3282
FCL = 1493 * 24.576/28.63636 ≈ 1281
Figure 91 shows the parameters from
28.63636 MHz XTAL operation.

Note: Although the two points for VGA72 and VGA75 look very close, it is anticipated that the
difference in the parameters is sufficient to distinguish between them.
