The frequency of operation is 2x or 4x the CLKIN frequency of operation. The MCF548X supports a single external reference
clock (CLKIN). This signal defines the frequency of operation for FlexBus and PCI, but SDRAM clock operates at the same
frequency as the internal bus clock. Please see the PLL chapter of the MCF548X Reference Manual for more information on
setting the SDRAM clock rate.
SDCLK is one SDRAM clock in (ns).
Pulse width high plus pulse width low cannot exceed min and max clock period.
Pulse width high plus pulse width low cannot exceed min and max clock period.
SDR_DQS is designed to pulse 0.25 clock before the rising edge of the memory clock. This is a guideline only. Subtle
variation from this guideline is expected. SDR_DQS only pulses during a read cycle and one pulse occurs for each data beat.
SDR_DQS is designed to pulse 0.25 clock before the rising edge of the memory clock. This spec is a guideline only. Subtle
variation from this guideline is expected. SDR_DQS only pulses during a read cycle and one pulse occurs for each data beat.
The SDR_DQS pulse is designed to be 0.5 clock in width. The timing of the rising edge is most important. The falling edge
does not affect the memory controller.
Because a read cycle in SDR mode uses the DQS circuit within the MCF548X, it is most critical that the data valid window
be centered 1/4 clk after the rising edge of DQS. Ensuring that this happens results in successful SDR reads. The input setup
spec is provided as guidance.
