Product specification
Picture Signal Improvement (PSI) circuit
TDA4670
Notes
1.
Crosstalk on output, measured in the unused channel when the other channel is provided with a nominal input signal
(CTI active).
A number of more than 31 burst key pulses repeats the counter cycle of delay time control.

S = START condition.
SLAVE ADDRESS = 1000 100X.
ACK = acknowledge, generated by the slave.
SUBADDRESS = subaddress byte, see Table 1.
DATA = data byte, see Table 1.
P = STOP condition.
X = read/write control bit.
X = 0, to write (the circuit is slave receiver only).
If more than 1 byte DATA is transmitted, then auto-increment of the subaddress is performed.
