3. GND and VGND are shorted internally.

Digital Video

Digital Video

LVCMOS
LVCMOS digital video can be enabled/disabled with control commands. In the open state, users can choose to output raw data (ORG), non-uniform correction (NUC) data, DNS Data, temperature (TEMP) data, and image processing (DRC) data. When choosing to use DRC data, the digital zoom and temperature display functions are not available.
LVCMOS digital video includes 1 Clock signal (Clock), 1 line valid (Line_Valid) signal, 1 valid frame signal (Frame_Valid), and 14 data signals (DV0-DV13).
Pixel data bits are divided into 8-bit and 14-bit. When ORG or TEMP data is produced, the data bits are 14-bits, namely DV[13:0], where DV0 is LSB and DV13 is the MSB. When the user selects DRC, the data bits are 8-bits, namely DV[7:0], where DV0 is LSB and DV9 is for the MSB.

LVCMOS Clock Frequency

Model Clock Frequency
GC-76| 12.857 MHz

Note:

1. Clock-rising edge sampling is recommended for DV.
2. The high level is valid for Line_Valid and Frame_Valid.
3. After Line_Valid is valid it lasts for n Clock, which corresponds to the data of the first column to the last column of the row in turn.

LVDS
LVDS digital video includes one clock signal (LVDS_CLK) and 4 data signals (LVDS_DATA1, LVDS_DATA2, LVDS_DATA3 and LVDS_DATA4) which can be easily analyzed by the domestic mainstream video coding/decoding chip.
LVDS digital video can be enabled/disabled by control commands. When it is enabled, the output of ORG data, NUC data, DRC data, DNS data, and TEMP data can be selected.

When choosing to use DRC data, the digital zoom and temperature display functions are not available.

LVDS Clock Frequency

VALID LINE| 3FFF| 0000| 0000| 2000| 3FFF| 0000| 0000| 2740

BT.656
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
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.

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 640×512 movement, each row contains 640×2=1280 clock cycles (N = 640), and each frame contains 512 rows (M=512).

CDS_2 Clock Frequency

Model Clock Frequency
GC-76| 45.0 MHz

BT.1120
BT.1120 digital video outputs signals line by line. It includes clock signals (Clock), frame valid signal, line valid signal, and 16 data signals (DV0 – DV15). As shown:

When BT.1120 digital video is selected, the digital zoom and temperature display functions are not available.

Protocols

MIPI Protocol
The GC-76 core uses 4-lane MIPI which includes 1 pair of source-synchronized clocks (MIPI_CLK+, MIPI_CLK-), and 4 pairs of data lines (MIPIDATA0+, MIPI DATA0-, MIPI_DATA1+, MIPI_DATA1-, MIPI_DATA2+, MIPI_DATA2-, MIPI_DATA3+, MIPI_DATA3-). The data format and electrical specifications conform to CSI-2 and D-PHY Protocols.

The clock signal enters the high-speed mode at the beginning of each frame and exits at the end of the frame. The inter-frame is in the low-power mode (the data and clock lines are both at 1.2V high level). The CLK frequency of the thermal core is 200MHz.

After the core is powered on it outputs MIPI digital video. Taking 640 x 512 temperature measurement as an example, the core is set to CDS_2 digital video, the output data format is RAW8 (standard MIPI CSI-2 protocol), and the area array should be set to (1280 x 2) *512, which needs to be spliced into 1280 x 512 x 16-bit data by the back end, with the low byte first. The first 640x 16-bits of a line of valid data are image data, and the last 640 x 16-bits are temperature data.

User Expansion Boards

There are different user expansion boards and accessories. The boards support multiple interfaces and serve many functions.

Maintenance

Cleaning the Germanium Lens
Do not use corrosive chemicals on the optical glass components. The germanium window surface is coated with anti-reflection coating. Dust, grease, and fingerprints will produce harmful substances and lead to a decline in performance, or cause scratches. If dirt is found, please use the following methods:

1. Use a blown balloon or a soft brush to clean the lens surface to avoid dust particles scratching the anti-reflection film on lens surface during the wiping process.
2. Use a soft cotton cloth or lens wiping paper and dip in alcohol or lens wiping liquid. Gently wipe the lens surface from the middle to the edge, paying attention to not crack the lens, or use too much wiping liquid. If the lens is still not clean, replace the cloth and repeat operation.

Disinfecting the Camera Surface
Do not use corrosive cleaning solutions on the optical glass components. Do not get the electronics wet. It is recommended to disinfect the camera surface regularly with a non-corrosive sanitizing product. Follow the directions provided by the manufacturer of the cleaning solution. Adhere to the sanitation protocols and cleaning schedule set forth by the employer.

Device Calibration
It is recommended to have device(s) re-calibrated annually. Contact customer service to schedule maintenance.

Storage
When the equipment is not in use, the device should be placed in a dust-free and moisture-free environment with a stable temperature and humidity.
DO NOT USE CORROSIVE CLEANING SOLUTIONS ON THE OPTICAL GLASS COMPONENTS. DISINFECT THE CAMERA SURFACE REGULARLY WITH A NON-CORROSIVE SANITIZING PRODUCT.
CALIBRATE YOUR DEVICES ANNUALLY. CONTACT CUSTOMER SERVICE TO SCHEDULE MAINTENANCE.
