System Clock
The clock to the KS8695PX is supplied by either a 25MHz ±50ppm crystal or by an oscillator. If an oscillator is used, it must
be connected to the XCLK1 input (pin E1) on the KS8695PX. If a crystal is used, it must be connected with a circuit similar
to the one shown below. The 25MHz input clock is used by an internal PLL to generate the programmable SDOCLK. SDO-
CLK is the system clock and can be programmed from 25MHz to 125MHz using the system clock and bus control register
at offset 0x0004. The CPUCLKSEL strap-in option on pin M15 needs to be pulled low for normal operation. SDICLK is used
to register the data read from the SDRAM back into the KS8695PX. The system designer must ensure that SDRAM timing
is met when routing SDOCLK back to SDICLK.
