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
