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 ΔΣADC AK5385Bs
from AKM Semiconductor, Incorporated are placed, and for DACs placed at the transmit IF signal
output and at the audio output, 24-bit ΔΣDAC 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 VSG-1, 24-bit ΔΣADCs and ΔΣDACs are implemented.
All these converters are operated at the sampling frequency of 96 kHz.
