3.8.6. Wideband CODEC

The MSM6250A device integrates a wideband voice/audio CODEC into the mobile station modem

(MSM). The CODEC supports two differential microphone inputs, one differential earphone output, one

single-ended earphone output, and a differential analog auxiliary interface on two single-ended

earphone output. The CODEC integrates the microphone and earphone amplifiers into the MSM6250A

device, reducing the external component count to just a few passive components. The microphone

(Tx) audio path consists of a two-stage amplifier with the gain of the second stage set externally. The

Rx/Tx paths are designed to meet the ITU-G.712 requirements for digital transmission systems.

3.8.7. Vocoder Subsystem

The MSM6250A device’s QDSP4000 supports AMR vocoder. In addition, the QDSP4000 has modules

to support the following audio functions: DTMF tone generation, DTMF tone detection, Tx/Rx volume

controls, Tx/Rx automatic gain control (AGC), Rx Automatic Volume Control (AVC), EarSeal Echo

Canceller (ESEC), Acoustic Echo Canceller (AEC), Noise Suppression (NS), and programmable, 13-

tap, Type-I, FIR, Tx/Rx compensation filters. The MSM6250A device’s integrated ARM7TDMI

processor downloads the firmware into the QDSP4000 and configures QDSP4000 to support the

desired functionality.

3.8.8. HKADC

TheMSM6250A device has an on-chip 8-bit analog-to-digital converter (ADC) which is intended to

digitize DC signals corresponding to analog parameters such as battery voltage, temperature, and RF

power levels. The MSM6250A device has six analog input pins which are multiplexed to the input of

the internal HKADC.

3.8.9. General-Purpose Input/Output Interface

The MSM6250A device has general-purpose bidirectional input/output pins. Some of the GPIO pins

have alternate functions supported on them. The alternate functions include USB interface, additional

RAM, ROM, general-purpose chip selects, parallel LCD interface, and UART interface.
