Preliminary specification
Advanced modem/audio analog front-end
UCB1300
The audio sample rate (f
sa
) is derived from the SIB interface clock pin (SIBCLK) and is programmable through the SIB
interface using AUD_DIV[n]. The audio sample rate is given by the following equation:

(7< AUD_DIV[n] < 128)
For example, a serial clock of 9.216 MHz, with a divisor of 12, results in an audio sample rate of 24.0 kHz. Both the rising
and the falling edges of SIBCLK are used in case AUD_DIV[n] is set to an odd number, which demands a 50% duty cycle
of SIBCLK to obtain time equidistant sampling.
