Functional Description
The first three sections of this chapter detail the main blocks in the device:
The final section describes the device level operating modes including suspend.
Video block
Overview
The analog 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 readout 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.
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.
Data synchronization can be achieved either by using the embedded codes within the data stream
or by making use of the dedicated FST and QCK pins.
