Notes) 1. The MOS structure of this IC has a low tolerance for static electricity, so full care should be given for
measures to prevent electrostatic discharge.
2. For noise and latch-up countermeasures, be sure to connect a by-pass capacitor (0.1µF or more)
between each power supply pin (VH, VL) and GND.
3. To protect the CCD image sensor, clamp the SUB pin output at VH before input to the CCD image
sensor.

CXD2470R
Serial Interface Control
The CXD2470R basically loads and reflects the serial interface data sent in the following format in the readout
portion at the falling edge of HDI. Here, readout portion specifies the horizontal period during which V1A/B and
V3A/B, etc. take the ternary value.
Note that some items reflect the serial interface data at the falling edge of VDI or the rising edge of SEN.

Detailed Description of Each Data
Shared data: D08 to D09 CTG [Category]
Of the data provided to the CXD2470R by the serial interface, the CXD2470R loads D10 and subsequent data
to each data register as shown in the table below according to the combination of D08 and D09 .

CXD2470R
Control data/shutter data: [Electronic shutter]
The CXD2470R realizes various electronic shutter functions by using control data D13 to D14 SMD and
shutter data D10 to D17 SVD, D18 to D27 SHD and D28 to D35 SPL.
These functions are described in detail below.
First, the various modes are shown below.
These modes are switched using control data D13 to D14 SMD.

→ SHD is expressed as 1C3h .
[Electronic shutter stopped mode]
During this mode, all shutter data items are invalid.
SUB is not output in this mode, so the shutter speed is the accumulation time for one field.
[High-speed/low-speed shutter mode]
During this mode, the shutter data items have the following meanings.
Symbol
Data
Description
SVD
D10 to D17
Number of vertical periods specification (00h ≤ SVD ≤ FFh)
SHD
D18 to D27
Number of horizontal periods specification (000h ≤ SHD ≤ 3FFh)
SPL
D28 to D35
Vertical period specification for high-speed shutter operation (00h ≤ SPL ≤ FFh)
The period during which SVD and SHD are specified together is the shutter speed. Concretely, when specifying
high-speed shutter, SVD is set to "00h". (See the figure.) During low-speed shutter, or in other words when
SVD is set to "01h" or higher, the serial interface data is not loaded until this period is finished.
The vertical period indicated here corresponds to one field in each drive mode. In addition, the number of
horizontal periods applied to SHD can be considered as (number of SUB pulses – 1).
Note) The bit data definition area is assured in terms of the CXD2470R functions, and does not assure the
CCD characteristics.

Further, SPL can be used during this mode to specify the SUB output at the desired vertical period during the
low-speed shutter period.
In the case below, SUB is output based on SHD at the SPL vertical period out of (SVD + 1) vertical periods.

Incidentally, SPL is counted as "00h", "01h", "02h" and so on in conformance with SVD.
Using this function it is possible to achieve smooth exposure time transitions when changing from low-speed
shutter to high-speed shutter or vice-versa.

CXD2470R
[HTSG control mode]
During this mode, all shutter data items are invalid.
The V1A/B and V3A/B ternary level outputs are stopped, so the shutter speed is the value obtained by adding
the shutter speed specified in the preceding vertical period to the vertical period during which these readout
pulses are stopped as shown in the figure.

∗ The HDI of this chart indicates the actual CXD2470R load timing.
∗ The numbers at the output pulse transition points indicate the count at the MCKO rise from the fall of HDI.
∗ The HDI fall period should be between approximately 3.0 to 13.4µs (when the drive frequency is 18MHz). This chart shows a period of 115ck (6.4µs).

∗ HDI' indicates the HDI which is the actual CXD2470R load timing.
∗ The phase relationship of each pulse shows the logical position relationship. For the actual output waveform, a delay is added to each pulse.
∗ The logical phase of ADCLK can be specified by the serial interface.

Notes for Power-on
Of the three –7.5V, +15.0V and +3.3V power supplies, be sure to start up the –7.5V and +15.0V power supplies
in the following order to prevent the SUB pin of the CCD image sensor from going to negative potential.
