MONITOR OUTPUT
By setting the register, the signal from MONOUT is
selectable. Alternatives are OFF, CDS output, AGC
output, or REFIN/CCDIN output. Even at the CDS
gain is set to a certain gain, the CDS output on
MONOUT is multiplied by 1/gain resulting the level
before CDS amplification.
The output level of MONOUT is shown below. The
IR3Y48M
MONOUT level is VCOM (1.1 V, TYP.) at zero
reference level. For the maximum amplitude (1.1 Vp-p),
the output level is 2.2 V (TYP.).
CAUTION :
VCOM pin does not have enough driving capabilities.

MAX. signal = 1.1 V
MAX. level = VCOM + 1.1 V
= 2.2 V

POLARITY INVERSION
Following timing pulse of IR3Y48M control can be
inverted by register setting :
q ADCK (A/D converter sampling pulse)
w SHR, SHD (CDS sampling clock)
e BLK, OBP, CCDCLP, ADCLP (Enable controls)
POWER SAVE
Power save mode is selectable for the sampling
frequency below 15 MHz.
The power consumption at this mode is lower than
20 MHz mode.
General Notice for Power Supply
It is recommended to supply both AVDD and DVDD
supply from single regulator.
(Observe absolute maximum rating specification :
DVDD ≤ (AVDD + 0.3 V) even at the power-up and
power-down sequence.)
Refer to "APPLICATION CIRCUIT EXAMPLE"
against noise of power supply.
