Description
1
ENA1
SSI Enable Strobe / ST-BUS Mode for Rin/Sout (Input)
. This pin has dual functions
depending on whether SSI or ST-BUS is selected.
For SSI, this strobe must be present for frame synchronization. This is an active high channel
enable strobe, 8 or 16 data bits wide, enabling serial PCM data transfer for Echo Canceller A
on Rin/Sout pins. Strobe period is 125 microseconds.
For ST-BUS, this pin, in conjunction with the ENB1 pin, will select the proper ST-BUS mode for
Rin/Sout pins (see ST-BUS Operation description). The selected mode applies to both Echo
Canceller A and B.

For ST-BUS, this pin, in conjunction with the ENA1 pin, will select the proper ST-BUS mode for
Rin/Sout pins (see ST-BUS Operation description). The selected mode applies to both Echo
Canceller A and B.

ENA2
SSI Enable Strobe / ST-BUS Mode for Sin/Rout (Input)
.This pin has dual functions
depending on whether SSI or ST-BUS is selected.
For SSI, this is an active high channel enable strobe, 8 or 16 data bits wide, enabling serial
PCM data transfer for Echo Canceller A on Sin/Rout pins. Strobe period is 125 microseconds.
For ST-BUS, this pin, in conjunction with the ENB2 pin, will select the proper ST-BUS mode for
Sin/Rout pins (see ST-BUS Operation description). The selected mode applies to both Echo
Canceller A and B.
