Connecting ADV7180 video decoder to i.MX35 CSI

Hi everyone,


I need to connect an ADV7180 video decoder to an i.MX537 on a custom board and it's my first time dealing with BT.656


The only example schematic I can find is the SABRE board but it uses the 16bit wide interface on the 64pin ADV7180 package and I would like to use the 8bit interface.

The i.MX53 datasheet (under "Sensor Interface Timings") states that for BT.656 the only control signal used is SENSB_PIX_CLK.
Does this mean that the interface is just data lines and clock?

The connection would then be:
P0 -> CSI0_D[12]
P1 -> CSI0_D[13]
P2 -> CSI0_D[14]
P3 -> CSI0_D[15]
P4 -> CSI0_D[16]
P5 -> CSI0_D[17]
P6 -> CSI0_D[18]
P7 -> CSI0_D[19]
LLC -> CSI0_PIXCLK
SDATA -> I2C_DATA
SCLK -> I2C_CLK
RESET -> GPIO

Can someone who has used the ADV7180 please confirm that these connections are correct, particularly the data pin allocations?

Do I need to connect the other ADV7180 pins (HS, VS/FIELD, INTRQ) to the i.MX35?

Thanks,

Jackson
