Electrical Characteristics

NOTE

•

All the timings for the SSI are given for a non-inverted serial clock

polarity (TXC/RXC = 0) and a non-inverted frame sync (TXFS/RXFS

= 0). If the polarity of the clock and/or the frame sync have been

inverted, all the timing remains valid by inverting the clock signal

TXC/RXC and/or the frame sync TXFS/RXFS shown in the tables and

in the figures.

•

All timings are on AUDMUX Pads when SSI is used for data transfer.

•

The terms WL and BL refer to Word Length (WL) and Bit Length (BL).

•

For internal Frame Sync operation using external clock, the FS timing is

same as that of TXD (for example, during AC97 mode of operation).

4.10.10.4 SSI Receiver Timing with External Clock

Figure 34 depicts the SSI receiver external clock timing and Table 53 lists the timing parameters for the

receiver timing with the external clock.
