Digital PC-camera signal processor including

SAA8116
FUNCTIONAL DESCRIPTION
The SAA8116 video processor has a very high level of
programmability:118 (8-bit) registersarededicatedforthe
Video Signal Processor (VSP), including Pulse Pattern
Generator (PPG) and Measurement Engine (ME), plus
23 registers for the Video Formatter and
Compressor (VFC). The SAA8116 can accept 8 to 10-bit
digital data from various VGA sensors: CCD (progressive)
or CMOS, with or without colour filters (see Table 1).

ENERATOR
The SAA8116 incorporates a PPG function, which can be
used for VGA CCD sensors, see Table 1.
Depending on the sensor type, an external inverter driver
is required to convert the 3.3 V pulses to a voltage suitable
for the CCD sensor used.

A total of 19 internal registers make a high level of

TIMING
The PPG module is not used with CMOS sensors. The
SAA8116 provides some flexibility on the frame size to
increase the range of applicable sensors (see Table 1). It
is possible to program the position, width and polarity of
the H and V signals. The output clock for the CMOS
sensor is selectable between single and double pixel
clock, including a programmable polarity.
The HV timing module can serve both as master or slave.
When serving as a slave, the V pulse only is needed since
the H pulse is internally derived from V by programming
the number of pixels per line.

IDEO WINDOWS
Several registers allow the definition of the optical black
window, the active video input window, the active video
output window and the measurement windows.
