MT9F002: 1/2.3-Inch 14 Mp CMOS Digital Image Sensor
Operating Modes
Operating Modes
By default, the MT9F002 powers up with the serial pixel data interface enabled. The
sensor can operate in serial HiSPi or parallel mode.
For low-noise operation, the MT9F002 requires separate power supplies for analog and
digital power. Incoming digital and analog ground conductors should be placed in such
a way that coupling between the two are minimized. Both power supply rails should also
be routed in such a way that noise coupling between the two supplies and ground is
minimized.
Caution ON Semiconductor does not recommend the use of inductance filters on the power supplies
or output signals.

Notes:
1. All power supplies should be adequately decoupled. ON Semiconductor recommends having 1.0F
and 0.1F decoupling capacitors for every power supply.
2. ON Semiconductor recommends a resistor value of 1.5k, but a greater value may be used for
slower two-wire speed.
3. This pull-up resistor is not required if the controller drives a valid logic level on SCLK at all times.
4. The GPI pins can be statically pulled HIGH or LOW and can be programmed to perform special func-
tions (TRIGGER/VD, OE_BAR, SADDR, STANDBY) to be dynamically controlled. GPI pads can be left
floating, when not used.
5. VPP, which is not shown in Figure 5, is left unconnected during normal operation.
