Product specification
YUV 8-bit analog-to-digital interface
TDA8753A
The TDA8753A registers have address F0, F1 and F2
hexadecimal notation. Whenever the received address
(decoded on the first 8 bits received) is one of these, the
event is recorded in such a way that the next data received
by the TDA8753A will be captured in the line
buffer BF0, BF1 and BF2 respectively.
When 8 bits have been received, the data reception state
is entered. The address reception state can also be exited
at any time when V50 goes HIGH. The F0, F1 and F2
registers may not be loaded properly if there is some
activity in progress on the incoming line.
D
ATA RECEPTION STATE
The next 8 bits are considered as data bits according to
the format of Fig.4.
When 8 data bits have been received, the data is recorded
in the BF0, BF1 or BF2 line buffers if the previous address
recorded was F0 hex, F1 hex or F2 hex respectively.
The bit count is then reset to zero and the address
reception state is entered. This state may be ended any
time when V50 goes HIGH but in that condition F0, F1 and
F2 registers may not be loaded properly.
