System Delay
To calculate the delay through the system (see Figure 3), assume that the transmit FIFO is almost
empty at the end of a burst. Then the next bit that enters the transmit FIFO will experience a system
delay (excluding propagation delay but including the internal logic delay) of approximately
=
×
(TG+TPR+TUW+TST)+TDAT+T
(3)
where TG is the time delay due to guard time (note that G = G1 = G2 = 32 bits), TPR is the time
delay due to the preamble, TUW is the time delay of the UW, TST is the time delay for status nibble
transmission, TDAT is the time delay for data transmission, and T
is the internal logic delay. For a
32 Kbps ADPCM voice signal, with a master oscillator (MO) of 16.384 MHz, this system delay
translates into 5.625 mS, which is sufficiently short that no echo-canceller is required.

Voice Mode Timing Information
For full-duplex voice mode operation, the W9310 generates the appropriate clock signals for
interfacing with a 32-Kbps ADPCM voice codec such as the Winbond W9320S CCITT G.721 ADPCM
codec. In particular, with an MO of 16.384 MHz, the MHz2_ST pin delivers the 2.048 MHz bit clock
