Theory of Operation

The audio SSI bus is available at the bluetooth interface connector (J3001). The SSI_FS (J3001-55),

SSI_CLK (J3001-57), SSI RX data signals (J3001-47 and J3001-49), and SSI TX data signals

(J3001-51 and J3001-53) are routed to the connector.

A dedicated USB interface is available at the bluetooth interface connector (J3001). The USB_DM

(J3001-33), USB_DP (J3001-35), and USB_VBUS (J3001-32) are routed to the connector. This USB

interface connects to the OMAP IC's USB 1 Port through the MAKO IC. The signal path is from

OMAP's 3 pin interface, USB1_TXEN (U6302-W16), USB1_DAT (U6302-W14), and USB1_SE0

(U6302-R13) to MAKO's USB transceiver (U6501- B8,C8, and D8). MAKO's USB differential output

is USB1_DP (U6051-N6) and USB1_DM (U6501-P7), which connects to the bluetooth interface pins.

The VBUS to the bluetooth interface is supplied by MAKO's VBUS 1 supply (U6501-H10) through

transistor Q6502.

3.2.9.10 Type 1 / GPIO

Provisions for a future Type 1 encryption interface have been provided, which requires the TX_Inhibit

(J3001-56), Key_Zeroize (J3001-58) and Wakeup (J3001-41) signals

The 60-pin connector (J3001) pin definition is summarized in
