6-1-3 BT.656
6-1-4 CDS_2
BT.656 digital video includes 1 Clock signal (Clock) and 8 data signals (dv0-dv7).
BT.656 digital video supports all functions including brightness/contrast
adjustment, polarity selection, palette selection, reticle control, digital zoom, and
image flipping functions.
It only supports output DRC data.
CDS_2 digital video contains 1 Clock signal (Clock), 1 frame valid signal (Vsync),
1 line valid signal (Hsync), and 16 DATA signals (DATA).
The video data consists of two parts, the first half of each row of data is divided
into an image, which conforms to the YUV422 format. The high 8-bits is the
brightness component, the low 8-bits is the chroma component, and the image
supports pseudo-color mapping. The second half of each row is divided into
temperature data. The actual significant bit is 14-bits, and the higher two bits
complement 0.

45.0 MHz
Note:
1.
The output image data format is YUV, the high 8-bit is Y component, the low 8-bit is UV
component.
2.
“T” stands for temperature data (effective data bits are 14-bits lower, two bits higher
complement 0), “TH” stands for 8-bits higher, and “TL” stands for 8-bits lower.
3.
External synchronization signal mode is adopted. “Vsync” represents frame synchronization
signal and “Hsync” represents row synchronization signal.
4.
The output data of each row is 2 times of the movement surface array N, such as 640x512
movement, each row contains 640x2=1280 clock cycles (N = 640), and each frame contains
512 rows (M=512).
PLEASE READ AND UNDERSTAND THE TABLES BEFORE SWITCHING THE UNIT ON.
