Sensor pulse pattern generator
The SAA8115HL incorporates a Pulse Pattern Generator
(PPG) function. The PPG can be used for medium
resolution PAL, CIF and VGA CCD-sensors (see Table 3).
Depending on the sensor type, an external inverter driver
should be required to convert the 3.3 V pulses into a
voltage suitable for the used CCD-sensor.
The active video size is 512

288 for medium resolution
PAL, 352

288 for CIF and 640

480 for VGA. The total

V size are 685
×
292 for medium resolution PAL/CIF
and 823
×
486 for VGA. It should be noted that additional
HD pulses are added during the vertical blanking interval
to reach a total of 312 lines in PAL and CIF modes and
525 lines in VGA mode as required by the SAA8112HL.
A high level of flexibility is available for the PPG thanks to
19 internal registers (see Section 9.1.3).
