Frame Counter Size

Data Formats

SN65LVDS315

SLLS881A – DECEMBER 2007 – REVISED MARCH 2008

The maximum size of frame_count is limited to 2046 lines. Transmitting more than 2046 active lines within one

frame causes an error if MODE is held high.

The SN65LVDS315 supports the transfer of following data formats:

Table 3. Supported Data Formats

DATA TYPE

ABBR.

COMMENT

YUV 422 image

YUV422

D[0:7] inputs are used as data inputs; The host processor must be configured to receive YUV 422

data

data; the SN65LVDS315 is transparent to these data formats (no special configuration required); The

camera sensor must provide a UYVY output data sequence (e.g. U1,Y1,V1,Y2,U2,Y3,V3,Y4,U3,Y5...)

YUV 420 image

YUV420

D[0:7] inputs are used as data inputs; The host processor must be configured to receive YUV 420

data

data; the SN65LVDS315 is transparent to these data formats (no special configuration required); The

camera sensor must provide an odd/even (or UYY.../ VYY...) output data sequence (e.g. odd like

U1,Y1,Y2,U3,Y3,Y4,... followed by an even line V1,Y1,Y2,V3,Y3,Y4,...)

RGB 888 image

RGB888

D[0:7] inputs are used as data inputs; The host processor must be configured to receive RGB888

data

data; the SN65LVDS315 is transparent to these data formats (no special configuration required); The

camera sensor must provide an output data sequence of B1,G1,R1,B2,G2,R2,...

RGB 565 image

RGB565

This data format can only be supported if the camera sensor outputs a 16-bit data format (two output

data

bytes of 8-bit each) with the following format:

First byte: B[0:4] and G[0:2] (G2 is MSB on device input D7)

Second byte: G[3:5] and R[0:4] (R4 is MSB on device input D7)

Raw bayer, 8-bit

RAW8

D[0:7] inputs are used as data inputs; The host processor must be configured to receive RAW8 data;

image data

The camera line length should be a multiple of 4 pixel; the SN65LVDS315 is transparent to these data

formats (no special configuration required); The camera sensor must provide an output data

sequence of P1,P2,P3,P4,,...
