Positive high impedance input to transmit preamplifier for microphone 1 connection.
Negative high impedance input to transmit preamplifier for microphone 1 connection.
Positive high impedance input to transmit preamplifier for microphone 2 connection.
Negative high impedance input to transmit preamplifier for microphone 2 connection.
High impedance single ended input to transmit preamplifier for line input connection.
Only 0dB gain is allowed.
Microphone Biasing Switch.
Auxiliary analog audio Left channel input.
Auxiliary analog audio Right channel input.
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.
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.
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.
Remocon function digital output.
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.
Pulse width modulated buzzer driver output.
I2C-bus interface serial clock input. SCL is asynchronous with the other system
clocks.
I2C-bus interface serial data input-output.
Left Right clock for Audio interface input.
Audio interface Clock input.
Audio interface Data input.
Master Clock Input for Audio Mode. Can also be used as Master Clock in Tone Only
and FM Modes.
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.
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.
