8.1 Signal Transition Levels

All input and output timing parameters are referenced to 1.5 V for both 0 and 1 logic levels.

All rise and fall transition timing parameters are referenced to VIL MAX and VIH MIN for input clocks, and VOL MAX and VOH MIN for output clocks.

8.2 Timing Parameters and Board Routing Analysis

The timing parameter values specified in this data sheet do not include delays by board routings. As a good board design practice, always account for such delays. Timing values may be adjusted by increasing/decreasing such delays. TI recommends using the available I/O buffer information specification (IBIS) models to analyze the timing characteristics correctly. If needed, external logic hardware such as buffers may be used to compensate any timing differences.

For inputs, timing is most impacted by the round-trip propagation delay from the DSP to the external device and from the external device to the DSP. This round-trip delay tends to negatively impact the input setup time margin, but also tends to improve the input hold time margins (see Table 1 and Figure 4).

Figure 4 represents a general transfer between the DSP and an external device. Figure 4 also represents board route delays and how they are perceived by the DSP and the external device.

  1. CEx stays active for 7 – the value of Read Hold cycles after the last access (DMA transfer or CPU access). For example, if read HOLD = 1, then CEx stays active for six more cycles. This does not affect performance, it merely reflects the overhead of the EMIF.

If write hold is set to 0, then CEx stays active for four more cycles. This does not affect performance, it merely reflects the overhead of the EMIF.
