IMAGE SENSOR SOLUTIONS
System Reset
The KAC-9630 is equipped with an integrated power on reset
block that will ensure that all configuration registers will power
up with their respective default values.
An external reset pin, reset, is provided so that the chip can be
reset at any time after power up without the need to power down
and power up.
This is a synchronous reset so a clock must be running on the
mclk pin. It takes one mclk clock cycle for the reset to take
effect.
In addition to the external reset pin it is possible to reset the
sensor by writing to the rest bit (res) in the Main Configuration
Register
automatically clear this bit upon completion of the reset.
Power Management
Power Up and Down
The KAC-9630 is equipped with an on-board power manage-
ment system allowing the analog and digital circuitry to be
switched off (power down) and on (power up) at any time.
The sensor can be put into power down mode by writing to the
power down bit (PwrDown) in the Main Configuration Register
(MCFG).
The digital master clock will be internally switched off. A clock
must be running at the mclk pin before power up can be
achieved.
When the power down bit is asserted during frame integration or
readout time, the sensor will enter power down state after the
frame has been read out completely.
Advanced Power Mode
In addition to the power up/power down feature, the analog
video amplifier can be powered down and its input signal can be
connected directly to the A/D as illustrated in figure 11.
This flexibility allows power dissipation to be traded of with sig-
nal gain as shown in the table below:
The video gain amplifier can be powered down and bypassed by
writing to the (PwdAmp) & (BypassAmp) bits in the Main config-
uration Register (MFCG)

Analog Gain
The analog signal out of the active pixel array can be amplified
up to 28.1 times in 32 logarithmic steps. The gain can be calcu-
lated as follows:
Where:
The gain setting can be programmed at any time, the internal
timing and control circuit will only update the gain setting during
the horizontal blanking time.
Video and Snapshot Mode
The image sensor can be operated in two modes, video and
snapshot.
Video Mode
In video mode the sensor will continually capture and read out
images at the programmed frame rate.
Snapshot Mode
In snapshot mode the sensor is externally triggered to capture
and read out a single frame.
Upon reset the senor will operate in snapshot mode. To operate
the sensor in video mode, bit 0 of the Main Configuration Regis-
ter (MCFG) must be set to a logic 0.
