GP 31 AFE
The analogue front end is a XWM8192 from Wolfson. This is a 16bits, 6MPS ADC. The red chan-
nel is used to digitalize the output of the CIS. The analogue signal is amplified by the transistor
Q320. This amplifier can be short cut by the resistor R312.
The Digicolor controls the ADC through a serial link and gets the data through a pixel bus
(PI_DATA7..0).
The reference voltages are filtered by 100nF in parallel with a 22uF to minimise the ripple.
