Functional Description
Video block
Overview
The analogue core of the video block contains a VGA sized pixel array. The integration time and
access for a row of pixels is controlled by the Y-address block. The row of pixels being read is
converted using a 10-bit in-column ADC. The digitised data is read out into the digital block for
formatting. The 10-b data is transferred to the co-processor over a 5-wire digital bus as two 5-b
nibbles. An alternative mode allows the transfer of the data as 8 bits per pixel with an additional
qualification clock signal (QCK)
The exposure or integration time for the pixel array is calculated by the external co-processor and
delivered to the sensor using the I2C interface.
