7 / 52 page  STw5094A 6/51 SIGNAL DESCRIPTION Type definitions: AI - Analog input, AO - Analog Output, DI - Digital Input, DO - Digital output, DOT - Digital Output Tristate, DIOD - Digital Input Output Open Drain, DIOT - Digital Input Output Tristate, P - Power Supply or Ground. Pin N° Name Type 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 microphone 3 connection. MIC3 can be used as monophonic input for the FM path in place of FML and FMR 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 Ω. The signal at this output can be: the sum of the Receive Speech signal from DR, FML (or MIC3) input, the Internal Tone Generator and the Sidetone signal, or the sum of the Audio Left channel, FML (or MIC3) input and the Internal Tone Generator, or can come from FML (or MIC3) input. E2 HPL AO Audio headphone amplifier Left channel output. This output can drive 50nF (with series resistor) or directly an earpiece transductor of 16 Ω. The signal at this output can be the sum of Audio Left channel, FML (or MIC3) input and Internal Tone Generator, or the sum of Receive Speech signal from DR, FML (or MIC3) input, Internal Tone Generator, Sidetone signal, or can come from FML (or MIC3) input. F4 HPR AO Audio headphone amplifier Right channel output. This output can drive 50nF (with series resistor) or directly an earpiece transductor of 16 Ω. The signal at this output can be the sum of Audio Right channel, FMR (or MIC3) input and Internal Tone Generator, or the sum of Receive Speech signal from DR, FMR (or MIC3) input, Internal Tone Generator, Sidetone signal, or can come from FMR (or MIC3) input. A3 REMOUT/OCK DO Remocon function digital output / Oversampled Clock out. 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 DIOD I2C-bus interface serial data input-output. C6 LRCK DIOT Left ⁄ Right clock or Frame Sync for Audio interface input in Slave mode, output in Master mode. D6 SCK DIOT Audio interface Serial Clock input in Slave mode, output in Master mode. D5 SDI DI Audio interface Data input. E5 AMCK DI Master Clock Input for Audio Mode. Can also be used as Master Clock in Tone Only and FM Modes. |
