Functional description summary

The VD66GY is a 1.5-megapixel global shutter image sensor featuring a matrix of 1124 x 1364 pixels. With its

global shutter operation, all pixels are synchronized to capture light at the same time. This removes the motion

blur that can affect rolling shutter image sensors, when capturing changing or moving scenes.

Once the exposure is finished, each pixel information is transferred in a storage node, before being read and

digitized one pixel row after the other. The image data are digitized using internal 10-bit ADCs. Additional gains

can be applied before ADC stage (for example, analog gain) or after ADC stage (for example, digital gain).

Following the digital conversion, various image preprocessing and correction algorithms can be applied into the

sensor before data output, such as autoexposure or binning.

The image data are output as frames of RAW8 or RAW10 data through a MIPI CSI-2 interface. The sensor can be

configured to operate with either 1 or 2 MIPI CSI-2 lanes to best fit with host processing requirements.

The VD66GY is synchronized to the rest of the system by means of an external clock, triggers, and general-

purpose input/output (GPIO) signals that can be used to enable synchronization of several sensor readouts or to

control strobe light sources during exposure time.

The device is fully configurable through the I²C serial interface and provides flexible frame-to-frame parameter

configuration changes via the use of programmable contexts. It also embeds a one-time programmable (OTP)

non-volatile memory to be written by 32-bit words.
