In a DIGIT 3000 system environment, the CIP 3250A re-
ceives the synchronization information at the FSY input
via the DIGIT 3000 FSY-protocol (see Fig. 2
–
7). The AVI
input receives the chroma multiplex information implicit-
ly with the rising edge of the AVI signal.

In a stand alone application, for example, RGB-analog-
to-digital conversion, a horizontal sync pulse must serve
the FSY input, and a vertical sync pulse must serve the
AVI input. The polarity of these two sync pulses can be
programmed via I
2
C registers <10>AVIINV and
<07>FSYINV.
Inside the CIP 3250A, synchronization information is be-
ing decoded and used to control clamping, DL2, skew fil-
ters, video control logic, input formatter, and output for-
matter as shown in Fig. 2

2.9. Digital Input Formats
–
YUV 4:2:2 (16 bit) from DIGIT 2000 and DIGIT 3000
(YUV as well as YCrCb)
–
YUV 4:1:1 (12 bit) from DIGIT 2000
–
input levels according to DIGIT 2000/DIGIT 3000
The CIP 3250A supports the YUV 4:1:1 (12 bit) standard
from DIGIT 2000, the YUV 4:2:2 (16 bit) standard from
DIGIT 2000, and the YUV 4:2:2 (16 bit) standard from
DIGIT 3000. Therefore, the CIP 3250A can be used in
either the DIGIT 2000 system environment or the DIGIT
3000 system environment. Refer to I
2
C registers
<06>DELAYU, <10>UVFRM3, and <10>UVFRM1 for a
correct setup. Additionally, within the DIGIT 2000 sys-
tem, a Y (luma) format conversion to ITU-R 601 can be
achieved via programming the I
2
C register <10>YLE-
VEL.

2.9.1. The Chroma Demultiplexers
In DIGIT 2000 mode, via pins 36 to 39, the CIP 3250A
receives the V and U signals from the C0 to C3 outputs
of the color decoder, time-multiplexed in 4-bit nibbles
(Fig. 2
–
8). For the digital signal processing, the 4-bit V
and U chroma nibbles are demultiplexed to 8-bit signals
by the V and U demultiplexers. Both demultiplexers are
clocked by the main clock. They are synchronized to the
V and U transmission during the vertical blanking period.
