I/O
- It is GND of the logic circuit.
O It is RFOK signal output terminal.
I Reset signal input terminal. (Active row)
I Command/parameter identification signal input terminal
A0=L:STB active=Address register set. A0=H:STB active= Parameter set.
I The data strove signal input terminal. It is signal to de the latch in LSI as
for the cereal data.
I
The clock signal input terminal to input and output the cereal data. Input
data from terminal SI is taken by standing up about this signal, and the
cereal data from the terminal SO is output with go down.
O
The cereal data and the status signal are output.
I
Cereal data input terminal.
I
The crystal oscillation control terminal. Please input the reset signal
before stopping the crystal oscillation. Moreover, the crystal oscillation is
steady and input the reset signal, please when moves from the state of
the crystal oscillation stop to the ordinary mode.
XTALEN=L:ordinary mode XTALEN=H:Crystal oscillation stop.
- Positive power supply supply terminal to logic circuit.
- Positive power supply supply terminal to D/A converter.
O
R-ch audio signal output terminal.
-
It is D/A converter GND.
-
The outside credit capacitor connection terminal for SCF regulator.
-
It is D/A converter GND.
O
L-ch audio signal output terminal.
-
Positive power supply supply terminal to D/A converter.
O
Output terminal of right channel voice data. PWM output.
O Left channel voice data audio output terminal. PWM output.
- Positive power supply supply terminal to crystal oscillation circuit.
O Crystal departure pendulum connection terminal (Output)
I Crystal departure pendulum connection terminal (Input)
-
It is GND of the crystal oscillation circuit.
-
Positive power supply supply terminal to logic circuit.
O
The output terminal of priemphasis information in sub code Q.
When the emphasis is added, high level is output. Polarity can be
switched by the command.
F6H LSB EP=0:Normal output EP=1:Reversing output.
O
Flag output terminal which shows that data under output is composed by
data which cannot be corrected.(active high)
I The cereal data input terminal to building DAC into. When DSP etc. are
not connected with latter part, it should be short with the terminal DOUT.
O It is an output terminal of the cereal voice data.
I Cereal clock input terminal to building DAC into.
x ao
The output voice data changes from DOUT by standing up about this
y
clock. The system connected with latter part must take data by standing
. i
up about this signal.
O
The output voice data changes from DOUT by standing up about this
clock.The system connected with latter part must take data by standing
up about this signal.
