... CODEC, and the processor interface. The functions can be controlled via 8-bit data bus. For the CODEC of the MSM7502, an MSM7543 is used as a core CODEC, so the MSM7502 provides the available bit clock range wider than the family product MSM6895. ...

... Initially, the ringing tone volume is set at a maximum and the tone combination is set Wamble tone by a combination of 1 kHz and 1.3 kHz. If these pins are used with no-load, tone volume cannot be controlled. When tone volume control is required, a load resistor must be connected between SA0 and SA1. MSM7502 4/35 ...

... During the whole system Power ON, the speech path from RMI to RMO0 and RMO1 is disconnected and the output of RMO0 and RMO1 is at the SG level (VA/2). The speech path is provided by processor control. A circuit example for adjustment of frequency characteristics Main amplifier gain without capacitors RPO RMI R1 C1 MSM7502 RMO0 5/35 ...

... TO signal is great, CAI should be connected via AC-coupling capacitor. At this time, insert an about 100 kW bias resistor between CAI and SGT. CAO is the analog output of CODEC. CAO should be connected to R1I via AC-coupling capacitor. A bias resistor is not required to R1I. During the whole system or CODEC power down mode, CAO is at the SG voltage level. MSM7502 8/35 ...

... PCMOUT data is shifted out at the rising edge of the BCLOCK signal. PCMOUT is left open after eight bits are shifted or when PLL goes out of synchronization. PCMOUT also is left open through processor control. In addition, a digital path between PCMIN and PCMOUT is formed through processor control. PCMOUT needs a pull-up resistor because of its open-drain circuit. MSM7502 9/35 ...

... By processor control, VLCD outputs a DC voltage between 0 and 1 about 0.25 V step. This is used to control the deflection angle of the LCD display. VLCD has the internal resistance value of about 1 kW, so the external load of over 100 kW should be used. During initialized state, VLCD outputs the voltage MSM7502 12/35 ...
