DS90UB954-Q1: MIPI output issue

Part Number: DS90UB954-Q1

Hi Teams,

I'm using 913 send 10bit RAW video to 954, and generate MIPI data to video grabber. But our grabber cannot recognize this MIPI data packet. (data CRC ok, but cannot split these data into a frame)

I have checked with another camera, some differences at the end of the data packet.

Please let me know any else I can try.

Thanks.

Imager: 1300*1000px 10bit DVP 96MHz PCLK

Serializer: 913A

+STP cable

Deserializer: 954 port1

Setting

Deserialzer:

0x1f,0x03 //400mbps per lane (problem still exists at 800mbps)

0x33,0x03 //4lane, continous clk

0x20,0x10 //Enabled FWD for RX Port 1, disabled FWD for RX Port 0

0x4c,0x12 //FPD3_PORT_SEL port1

(I2C pass through/I2C alias)

0x7c,0x01 // FV,LV setting

0x70,0x6b // RAW10 DT

0x6d,0x73 // 913A 10-bit STP mode

0x10,0xc5 //Enable 954 GPIO0,1 OUTPUT FV and LV 0x11,0xe5

0xbc,0x80 // FV_MIN_TIME (problem still exists at 0x00)

Serializer:

0x05,0x25 //overrides to 10bit mode

Current status:

PASS, LOCK : high

No forward channel parity error

913 PCLK detect: STABLE, HIGH

0x73,0x74 = DEC1300 line

0x75,0x76 = DEC 2000 byte

No CRC error occurs on video grabber

HSYNC, VSYNC output on 954, almost the same with sensor side. (VSYNC inverted)

FV-LV=690us, =66240*PCLK

MIPI data

Camera B is a 12bit raw camera using 913 and coax.

It can be displayed on the same backend grabber via 954.
