3.2.4.10 Peripheral Devices
The OMAP processor is equipped with multiple buses and interfaces that are configured for
peripheral interconnection.
3.2.4.10.1 Receive and Transmit SSI
These two interfaces are dedicated for communicating with the RF deck digital interface, carrying
receive and transmit base band signals. The OMAP processor generates the clock and FSYNC
signals for the receive SSI interface. The RF deck generates these signals for the transmit SSI
interface.
Figure 3-26. RX / TX SSI Configuration
3.2.4.10.2 Audio SSI
OMAP's McBSP1 interface is configured as a SSI interface dedicated to carry transmit and receive
audio data to peripheral devices. The peripherals connected to this bus include MAKO, Audio
CODEC, MACE and CPLD. The bus also connects to the option board via J3001. MAKO generates
the clock and frame sync signals for this bus.
