CCD Vertical Clock Driver
CXD1267AN
Description
The CXD1267AN is a vertical clock driver for CCD
image sensors. This IC is the successor of the
CXD1250N with attractive features.
Power consumption is reduced approximately 30%
for the CXD1267AN version.
20 pin SSOP (Plastic)
Features
1) Substrate voltage (Vsub) generator is built-in.
• Variable Vsub in the range of 4.0V to 18.5V.
• Reduction of peripheral parts saves space.
2) Only two power supplies (+15V and –8.5V) are
needed.
3) 3.3V clock interface is acceptable.
4) 20-pin SSOP package is used.
5) Low power consumption
90mW (CXD1267N)
62mW (CXD1267AN)
approximately 30% reduction

Input voltage
Note) Operating amplifier maximum output voltage is restricted as shown in the formula below depending on
supply voltage setting of VH and VL.
Maximum output voltage VDCOUT (max) ≈ VH + | VL | – 0.8V
For instance, when VH = 14.5V and VL = –6.0V, output voltage is saturated at approximately 19.7V as
shown above figure.
