2.5 Video Interfaces
The TMS320DM6467 EVM has a 16 bit divideable video input port and 16 bit dividable
output port to support a variety of user applications. Both ports can be used as two
eight bit ports when the appropriate interface only requires 8 bits. High definition
interfaces require all 16 bits.The EVM incorporates dual TVP5147 decoders or a
TVP7002 tied to the input port. An ADV7343 is connected to the output ports providing
standard video or component video interfaces.
2.5.1 Video Input Port Interfaces
The TMS320DM6467 EVM supports video capture via the devices dual 8 bit or single
16 bit internal video ports. The EVM incorporates dual Texas Instruments TVP5147s
to decode composite video or S-video inputs into the TMS320DM6467 device. P7 is
used for the S-video inputs and J13 for the composite inputs on the EVM.
Corresponding High Definition component video can be driven into the
TMS320DM6467 video input port via a TVP7002 when the video port on the EVM is
configured for 16 bit mode. The component inputs are driven into RCA connectors
J1, J2, J3.
User inputs can be driven via daughter card connector DC_P2 when the on board
multiplexers are configured for daughter card use. The figure below illustrates the input
port configurations. The on board CBT multiplexer input modes are controlled via the
CPLD control register 1 as discussed in section 2.12.
