I am designing my own board based on ns7520. I have removed the CY2309,and direct connect the CLK of the CPU to the SDRAM’s CLK. Can my board work? Because I think the CY2309 only provide multi clk singals. But I only use one clk signals.
There are two clocks - the XTAL source and BCLK BCLK connects directly to the SDRAM and is different from the clk/pll source for the NS7520
