Digital CCD Camera Head Amplifier
CXA3796N
Description
The CXA3796N is a bipolar IC developed as a head amplifier for digital CCD cameras. This IC provides the
following functions: correlated double sampling, AGC for the CCD signal, A/D sample and hold, blanking, A/D
reference voltage, and an output driver.
(Applications: CCD cameras)
Features
‹ High sensitivity made possible by a high-gain AGC amplifier

‹ Regulator output pin provided for A/D converter reference voltage
‹ Built-in sample-and-hold circuits for camera signals required by external A/D converters
<Changes and improvements from CXA2096N>
‹ Selectable maximum gain of AGC amplifier (MAXGAIN mode)
‹ Minus gain setting of AGC amplifier (GAINSHIFT mode)
‹ CCDLEVEL output blanking function
‹ Input dynamic range expansion
‹ Noise characteristics improvement

CDS (SH1, SH2, SH3):
The CCD signal from the CCD image sensor is input to PIN and DIN where correlated double sampling (CDS)
is performed by SH1, SH2 and SH3. The precharge level of the CCD output signal is sampled, held and output
by the SH2 output, and the signal level is sampled, held and output by the SH3 output. SH1 and SH2 are the
sample-and-hold circuits for the precharge level; SH3 is the sample-and-hold circuit for the signal level.
CDSCLP 1, 2:
CDSCLP1 and 2 stabilize the input signal DC level, clamp (CLPDM) the input signal during the idle transfer
interval for the purpose of eliminating the AGC input offset, and adjust the DC level ([*1], [*2]) of SH2 and SH3
in line with VREF. CDSCLP1 is the clamp circuit for the precharge level, and CDSCLP2 is the clamp circuit for
the signal level.
AGC:
AGC is the gain control amplifier for the camera signal.
The gain can be varied from –1 to +31dB (when MAXGAIN = OPEN, GAINSHIFT = VCC) by adjusting the
AGCCONT voltage control VAGCCONT from 1.65 to 3.3V.
* Gain width can be changed by MAXGAIN = VCC/OPEN/GND, GAINSHIFT = VCC/OPEN/GND setting.
CAM SH:
CAM SH is the sample-and-hold circuit for synchronizing the data read-in timing for the external A/D.
Sampling is possible according to the approximately 10ns sampling pulse width input to XRS.
AGCCLP:
The basic black level is set ([*3]) by clamping the AGC output waveform with the CLPOB clock during the OPB
interval. When PBLK is High and CLPOB is Low, the clamping circuit operates, adjusting the AGCCLP current
so that the DRVOUT potential equals the OFFSET potential (which is determined by the voltage applied to the
OFFSET pin), thus setting the AGCCLP potential. The AGCCLP capacitance is connected to the AGCCLP pin.
DC SHIFT:
This circuit functions when AGCCLP operates, following the AGCCLP potential and forcing a DC shift of the
AGC output waveform OPB interval to the basic black level. When AGCCLP is not operating, the basic black
level is maintained at its previous setting.
BLK SW:
The black level is calibrated by blanking the black level signal of the AGC output waveform so that it does not
fall below the basic black level and replacing the DC potential with VRB. ([*4])
The signal is blanked when PBLK is Low.
OFFSET:
OFFSET controls the DRV output waveform black level offset.
The offset of the DRVOUT camera signals can be adjusted when a voltage is applied to OFFSET. ([*5])
The voltage controlled by OFFSET is output as the DRV output DC offset via AGCCLP, DCSHIFT, CAMSH
and BLKSW.
When the OFFSET voltage is 1.65 to 3.3V, DRVOUT DC can vary in a linear fashion from VRB + 110mV to VRB.
In addition, when the OFFSET voltage is 0V, DRVOUT DC is preset to VRB + 40mV.
DRV:
DRV drives the external A/D. The current that flows to the last-stage amplifier in DRV is controlled by applying
voltage to the ICONT pin, making it possible to adjust the rise time of the output waveform, which affects the
external A/D load capacitance. The variable range is 1.65 to 3.3V, with 1.65V yielding the maximum and 3.3V
yielding the minimum. The optimum rise time for the external A/D input capacitance can be selected.
- 14 -
CXA3796N
VRT DRV, VRB DRV:
These are the external A/D reference voltage drivers. These circuits are connected to A/D VRT and VRB,
supplying 2.585V and 1.485V, respectively, when VCC is 3.3V. The IC's internal primary voltage is also
generated on the basis of the VRT and VRB voltage.
GAINSHIFT:
AGC gain curve can be shifted by setting GAINSHIFT as follows.
0dB shift
Š When applying VCC
Š When OPEN
–3dB shift
Š When GND
–6dB shift
MAXGAIN:
AGC MAX gain can be changed by setting MAXGAIN as follows.
34dB * when VAGCCOUNT = 3.0V
Š When applying VCC
Š When OPEN
26dB * when VAGCCOUNT = 3.0V
Š When GND
30dB * when VAGCCOUNT = 3.0V
CCDLEVEL BUF:
This is buffer to monitor SH3 output camera signal and output from CCDLEVEL. SH3 output is output to
CCDLEVEL when PBLK = High and internal generation voltage (Vref) is output when PBLK = Low.
