Configuring the Board
7.6
Configuring the Outputs
All eight outputs are connected to SMA through AC-coupling. Output Y4-Y7 can provide HCSL clocks.
These outputs have 50
Ω
-to-GND (not populated) and series-resistors (0-
Ω
populated) options. Placing
50-
Ω
resistors and possibly adjusting the series resistor values (up to 33
Ω
) improves ringing if the outputs
are configured as HCSL.

Using the MSP430 as a Bootloader
The onboard MSP430G2001 is a bootloader for the CDCM6208. A separate application note describes
how to generate, debug, and load the needed software for the MSP430.
SW1 and SW2 must be in the OFF position while SW3 must be in the ON position for communication with
the MSP430 (U10) via JTAG (P12) and for communication of the MSP430 with the CDCM6208. Also note
that the MSP430 requires a minimum of 1.8 V for nominal operation. Once the program is loaded to the
MSP430, resetting power to the MSP430 makes the bootloader execute again – after this occurs, the
MSP430 enters a low-power mode.
