SDA9410
Preliminary Data Sheet
Input format conversion (IFCM/IFCS)
In case of CCIR 656 three modes are supported (FORMATM/FORMATS=11 means full
CCIR 656 support, including H-, V-Sync and Field signal, FORMATM/FORMATS=01
means only data processing, H- and V-Sync have to be added separately according
PAL/NTSC norm, FORMATM/FORMATS=10 means only data processing, H- and V-
sync have to be added separately according CCIR656-PAL/NTSC norm). The
representation of the samples of the chrominance signal is programmable as positive
dual code (unsigned, I²C Bus parameter TWOINM/TWOINS=0) or two's complement
code (TWOINM/TWOINS=1, "I²C Bus" on page 117, I²C Bus parameter 0Bh,2Dh).
Inside the SDA 9410 all algorithms assume positive dual code.

Input sync formats
The amplitude resolution for each input signal component is 8 bit, the maximum clock
frequency is 27 MHz. Consequently the SDA 9410 is dedicated for application in high
quality digital video systems.
