I/O Interface Connector Provisions
The connector interface is versatile, allowing different connection
arrangements depending on the user selected interface. A 20-position dual
inline header connector, J11, is used to interface the TMS320C5x DSP and
microcontroller devices to the EVM. It is hard-wired to the input/output signals
of the ADC through the SN74AHC244. J12 is a dual row, 24-position header,
used to interface both TMS320C2xx/TMS320C54x DSPs to the EVM. The
headers are readily available 100-mil center connectors. A ribbon cable with
the corresponding female plug, mates to the header the appropriate DSP or
microcontroller EVM. Figure 3–1 shows the signal arrangement for J11 and
J12.
Ideally, J12 should be arranged so that the clock lines have a ground line on
either side in the ribbon cable to minimize crosstalk. If possible, every other
conductor in the ribbon cable should be grounded. However, keep in mind that,
many DSP/microcontroller EVM boards restrict the interface connector size,
and signals going to the output connector are not routed for minimum
crosstalk.
An isometric drawing showing the ADC EVM connected to the TMS320C54x
DSKplus EVM can be found in literature number SLAU030 (TMS320C54x
DSKplus Adapter Kit).
