Description
B1
MIC1P
AI
Positive high impedance input to transmit preamplifier for microphone 1 connection.
B2
MIC1N
AI
Negative high impedance input to transmit preamplifier for microphone 1 connection.
A2
MIC2P
AI
Positive high impedance input to transmit preamplifier for microphone 2 connection.
A1
MIC2N
AI
Negative high impedance input to transmit preamplifier for microphone 2 connection.
C1
MIC3
AI
High impedance single ended input to transmit preamplifier for line input connection.
Only 0dB gain is allowed.
B3
MBIAS
AO
Microphone Biasing Switch.
E1
FML
AI
Auxiliary analog audio Left channel input.
D2
FMR
AI
Auxiliary analog audio Right channel input.
F2,F1
LSP LSN
AO
Receive analog amplifier complementary outputs. This differential output can drive
50nF (with series resistor) or directly an earpiece transductor of 8
. The signal at this
output can be: the sum of the Receive Speech signal from DR, the Internal Tone
Generator, and the Sidetone signal, or the sum of the Audio Left channel and the
Internal Tone Generator, or can come from FML input.
E2
HPL
AO
Audio headphone amplifier Left channel output. This output can drive 50nF (with
series resistor) or directly an earpiece transductor of 30
. The signal at this output
can be the sum of Audio Left channel and Internal Tone Generator, or the sum of
Receive Speech signal from DR, Internal Tone Generator, Sidetone signal, or can
come from FML input.
F4
HPR
AO
Audio headphone amplifier Right channel output. This output can drive 50nF (with
series resistor) or directly an earpiece transductor of 30
. The signal at this output
can be the sum of Audio Right channel and Internal Tone Generator, or the sum of
Receive Speech signal from DR, Internal Tone Generator, Sidetone signal, or can
come from FMR input.
A3
REMOUT
DO
Remocon function digital output.
C4
REMIN
DI
Remocon function input. A high level at this pin is detected as a non pressed key,
while a low level is detected as a pressed key.
E6
BZ
AO
Pulse width modulated buzzer driver output.
F6
SCL
DI
I2C-bus interface serial clock input. SCL is asynchronous with the other system
clocks.
F5
SDA
DIO
I2C-bus interface serial data input-output.
Left
Right clock for Audio interface input.
C6
LRCK
DI
D6
SCK
DI
Audio interface Clock input.
D5
SDI
DI
Audio interface Data input.
E5
OCK
DI
Master Clock Input for Audio Mode. Can also be used as Master Clock in Tone Only
and FM Modes.
A6
DX
DOT
Transmit Data output: Data is shifted out on this pin during the assigned transmit time
slots. Elsewhere DX output is in the high impedance state. In delayed and
non-delayed normal frame sync modes, voice data byte is shifted out from tristate
output DX at the MCLK frequency on the rising edge of MCLK, while in non-delayed
reverse frame sync mode voice data is shifted out on the falling edge of MCLK.
A5
DR
DI
Receive data input: Data is shifted in during the assigned Received time slots In
delayed and non-delayed normal frame sync modes voice data byte is shifted in at
the MCLK frequency on the falling edges of MCLK, while in non-delayed reverse
frame sync mode voice data byte is shifted in on the rising edge of MCLK.
