Notes:
1. All power supplies must be adequately decoupled.
2. Aptina recommends using a resistor value of 1.5kΩ, but a greater value can be used for slower two-wire
speed.
3. This pull-up resistor is not required if the controller drives a valid logic level on SCL at all times.
4. VAA and VAA_PIX must be tied together.
5. VPP, 6-7V (typically 6.2V), is used for programming OTPM. This pad is left unconnected during normal
operation.
6. The parallel interface output pads can be left unconnected if the serial output interface is used.
7. Aptina recommends that 0.01μF, 0.1μF, and 1μF decoupling capacitors for each power supply are
mounted as close as possible to the pad. Actual values and results may vary depending on layout and
design considerations.
8. For MIPI configuration, TEST must be tied to VDD_IO. For CCP2, TEST must be tied to GND.
9. ATEST1_TOP, ATEST2_TOP, ATEST1_BTM, and ATEST2_BTM should be floating.
10. The serial interface output pads can be left unconnected if the parallel output interface is used.
11. GPI can be used to distinguish module maker. If not used, it should be grounded.
12. When using external VCM, VCM_ISINK must be floating and VCM_GND must be connected to DGND.
