• Manufacturer Part Number: LUPA-4000
• Description: 4M Pixel CMOS Image Sensor
• Manufacturer: CYPRESS [Cypress Semiconductor]

An overview of the supplies is given in table 8 and 9. Table 9 summarizes the
supplies related to the pixel array signals, where table 8 summarizes the supplies
related with all other modules.

The maximum currents mentioned in table 8 and 9 are peak currents which occur once
per frame (except for Vres_ds in multiple slope mode). All power supplies should be
able to deliver these currents except for Vmem_l and Vpre_l, which must be able to
sink this current.
The maximum peak current for Vpix should not be higher than 500mA. It is important
to notice that no power supply filtering on chip is implemented and that noise on these
power supplies can contribute immediately to the noise on the signal. Especially the
voltage supplies Vpix and Vaa are important to be well noise free.
