Hi,
i want to create a system below:
CMOS Sensor(OV2710,DVP INTERFACE)=>>> TMS320DM6437Q=>>>LCD(RGB)
the DVP infterface is the general digital video port, include: PCLK/VD/HD/DIGITAL[9:0], is the VPFE support this DVP interface? addtionally,OV2710 need a system clock input XVCLK(24M Hz), i didn't see it in VPFE, where pin can provide the clock to sensor?
Hi Rob,
Rob Jason said:the DVP infterface is the general digital video port, include: PCLK/VD/HD/DIGITAL[9:0], is the VPFE support this DVP interface?
From what I can find, DM643x device support the below video input signals (VPFE):
PCLK/VD/HD/C_WE/C_FIELD/CI[7:0]/YI[7:0]
For detail, refer to DM643x datasheet:
Table 2-19. VPFE Terminal Functions
6.10.1 Video Processing Front-End (VPFE)
6.10.1.1 CCD Controller (CCDC)
6.10.1.2 Preview Engine
6.10.1.6 VPFE Electrical Data/Timing

I also can not find VPFE pin with such functionality. You need to find other DM643x device pin or use external clock generator. For DM643x pins, you might check if CLKOUT0 pin will be useful for you. Check DM643x datasheet regarding CLKOUT0 info.
You can also refer to DM64x EVM, and check how TVP5146M2 video decoder is connected to VPFE:
