Power and grounding recommendations
When designing a printed-circuit board for applications
such as PC cameras, surveillance cameras, camcorders
and digital still cameras, care should be taken to minimize
the noise.
For the front-end integrated circuit, the basic rules of
printed-circuit board design and implementation of analog
components (such as classical operational ampliers)
must be respected, particularly with respect to power and
ground connections.
The following additional recommendation is given for the
CDS input pin(s) which is/are internally connected to the
programmable gain amplier:
The connections between the CCD interface and the CDS
input should be as short as possible and a ground ring
protection around these connections can be benecial.
Separate analog and digital supplies provide the best
solution. If it is not possible to do this on the board then the
analog supply pins must be decoupled effectively from the
digital supply pins. If the same power supply and ground
are used for all the pins then the decoupling capacitors
must be placed as close as possible to the IC package.
In a two-ground system, in order to minimize the noise
through package and die parasitics, the following
recommendation must be implemented.
All the analog and digital supply pins must be decoupled to
the analog ground plane. Only the ground pin associated
with the digital outputs must be connected to the digital
ground plane. All the other ground pins should be
connected to the analog ground plane. The analog and
digital ground planes must be connected together at one
point as close as possible to the ground pin associated
with the digital outputs.
The digital output pins and their associated lines should be
shielded by the digital ground plane which can then be
used as a return path for digital signals.
