Semiconductor SAO+, SAO-
MSM7590L-01
Differential analog outputs for sound output. Control register data CR4-B5 determines the output pins (AOUT+ and AOUT- /SAO+ and SAO) for the voice signal and an acoustic component of the sound tone, DTMF tone, R tone, F tone, and various types of tones at either the VFRO pin or the SAO+ and SAO- pins. The output load conditions of these pins are the same as those of AOUT+ and AOUT-. SG Analog signal ground. The output voltage of this pin is approximately 1.4 V. Put the bypass capacitors (10 F in parallel with 0.1 F ceramic type) between this pin and AG to get the specified noise characteristics. During power-down, this output voltage is 0 V. The SG voltage if necessary, should be via a buffer. AG Analog ground. DG Digital ground. This ground is separated from the analog signal ground pin (AG). The DG pin must be kept as close as possible to AG on the PCB. VDD +3 V power supply. PDN/RESET Power down and reset control input. A "0" level makes the IC enter a power down state. At the same time, all control register data are reset to the initial state. Set this pin to "1" during normal operating mode. The power down state is controlled by a logical OR with CR0-B5 of the control register. When using PDN/RESET for power down and reset control, set CR0-B5 to digital "0". The reset width (during "L") is 200 ns or more. MCK Master clock input. The frequency must be 10.368 MHz. The master clock signal may be asynchronous with BCLK, XSYNC, and RSYNC.

Semiconductor PCMSO
MSM7590L-01
Transmit PCM data output. PCM is output from MSB in synchronization with the rising edge of BCLK and XSYNC. PCMSI Transmit PCM data input. This signal is converted to the transmit ADPCM data. PCM is shifted in synchronization with the falling edge of BCLK. Normally, this pin is connected to PCMSO. PCMRO Receive PCM data output. PCM is the output signal after ADPCM decoder processing. This signal is output serially from MSB in synchronization with the rising edge and BCLK and RSYNC. PCMRI Receive PCM data input. PCM is shifted on the rising edge of the BCLK and input from MSB. Normally, this pin is connected to PCMRO. IS Transmit ADPCM signal output. After having encoded PCM with ADPCM, this signal is output from MSB in synchronization with the rising edge of BCLK and XSYNC. This pin is an open drain output and remains in a high impedence state during power-down. IS requires a pull-up resistor. IR Receive ADPCM signal input. This input signal is shifted serially on the falling edge of BCLK in synchronization with RSYNC and input from MSB. BCLK Shift clock input for the PCM data (PCMSO, PCMSI, PCMRO, PCMRI) and the ADPCM data(IS, IR) . The frequency is set in the range of 64 kHz to 2048 kHz.

MSM7590L-01
XSYNC Transmit PCM and ADPCM data 8 kHz synchronous signal input. Synchronize this signal with BCLK signal. XSYNC is used to indicate the MSB of the transmit serial PCM and ADPCM data stream. Be sure to input the XSYNC signal because it is also used as the input of the timing generator. RSYNC Receive PCM and ADPCM data synchronous signal input. Synchronize this signal with BCLK signal. RSYNC is used to indicate the MSB of the receive serial PCM and ADPCM data stream. VOXO Transmit VOX function signal output. VOX function recognizes the presence or absence of the transmit voice signal by detecting the signal energy. "1" and "0" levels set on this pin correspond to the presence and the absence of voice, respectively. This result appears at the register data CR7-B7. The signal energy detect threshold is set by the control register data CR6-B6, B5. VOXI Signal input for receive VOX function. A "1" level at VOXI indicates the presence of a voice signal. The decoder block processes normal receive signal, and the voice signal appears at the analog output pins . The "0" level indicates the absence of a voice signal. Background noise generated in this device is transferred to the analog output pins. The background noise amplitude is set by the control register CR6. Because this signal is ORed with the register data CR6-B3, set the control register data CR6-B3 to digital "0".

DTMF low-group-tones .................................... -16 dBm0 DTMF high-group-tones and others............... -14 dBm0 For example, when selecting +8 dB (B6, B5, B4) = (1,1,1) as a transmit gain, each tone signal amplitude with an analogical expression on the pin PCMSO becomes as follows . DTMF low-group tones .................................... -8 dBm0 DTMF high-group tones and other tones ...... -6 dBm0 Gain setting for the side tone (path to receive side from transmit side) and the receive side tone is performed by register CR3.

The tone generator gain setting table for the receive side, as shown in Table-4, depends upon the following reference level. DTMF low-group tones ................................ -2 dBm0 DTMF high-group tones and others ............ 0 dBm0 For example, when selecting -6 dB (B3, B2, B1, B0) = (1, 1, 1, 1) as a tone generator gain, each DTMF tone signal amplitude on SAO+/SAO- or VFRO is as follows. DTMF low-group tone .................................. -8 dBm0 DTMF high-group tone or other tones ....... -6 dBm0

Notes for Mounting the Surface Mount Type Package The SOP, QFP, TSOP, SOJ, QFJ (PLCC), SHP and BGA are surface mount type packages, which are very susceptible to heat in reflow mounting and humidity absorbed in storage. Therefore, before you perform reflow mounting, contact Oki's responsible sales person for the product name, package name, pin number, package code and desired mounting conditions (reflow method, temperature and times).
