•
The FDTI-2232D is self-powered by 3.3V_USB from the mini-USB connector. It provides bridges
the USB interface and JTAG port for the Tsi620, and also provides a USB to UART interface for
the AFS600.
•
JTAG connectors for the following:
— TI 6488 DSP (60-pin emulator)
— Tsi620 JTAG
— Actel FPGA and Stratix3 JTAG chain access

Local I2C Bus
There are two segments of the local I2C bus (see
Figure 10
):
•
3.3V I2C bus: The Tsi620 is I2C master. This bus includes the Tsi620 I2C EEPROM and two SFP
optical transceivers.
•
1.8V I2C bus: The DSP is I2C master. This bus includes the DSP, I2C EEPROM, and CDCL6010.
