*1 DSP: digital signal processor
*2 ADC: A/D converter
*3 DAC: D/A converter
The heart of the signal processing function is a 32-bit floating point TMS320C6726B DSP from Texas Instruments
Incorporated (Figure 4-2) and it is operated at the clock frequency of 221 MHz.
For ADCs placed at the receive IF signal input and the microphone input, 24-bit ΔΣ ADC AK5385Bs from AKM
Semiconductor, Incorporated are placed, and for DACs placed at the transmit IF signal output and at the audio output, 24-
bit ΔΣ DAC AK4382As also from AKM Semiconductor, Incorporated are placed. For other applications such as at the
external terminals, USB audio, and audio input to and output from the optional VGS-1, 24-bit ΔΣ ADCs and ΔΣ DACs
are implemented. All these converters are operated at the sampling frequency of 96 kHz.
