AD***66 Evaluation Board Rev. A Settings: Place a 25 MHz oscillator in socket U4. This clocks the ADC, DAC and Blackfin PPI. Supply an analog signal to the ADC via the J4 RXIN SMA connector. The DAC on the AD***66 is designed to handle broadband communications data. Therefore, when testing the interface, it is best to use analog input signals with frequency content of 200 kHz and above. The J5 SMA connector is an analog output from the DAC that can be routed to an oscilloscope to view the DAC output signal. The TX port on the AD***66 should be connected to the J3 (HSC interface to ADC) header on the extender card upside-down. Hence, with the right connection in place, the top of the AD***66 board should face in the same direction as the back of the extender card. A short RJ45 cable should be used to connect the SPI ports on the AD***66 board and the extender card. dip-switches SW2,4,5,6: ALL OFF SW3: 1,2 ON, 3,4 OFF jumpers: JP54 (solder contact): closed L3->L12 (power supply jumpers): all closed JP3, JP7: all closed JP67,68: close 2<->3 JP 90, 91, 92: close 1<->3 JP77, JP78: close 1<->2 Extender Board Settings: ADDS-BF561-EZEXT SW1 (DIR_CONTROL): 1: ON 2-6: OFF SW2: 1,2: ON 3,4: OFF SW3: 1-4: ON SW4: 1-6: OFF P7, P10, P37: Open P36: Closed ** If using the now obsolete ADDS-BF533-1-EZEXT ** SW1 (DIR_CONTROL): 1: ON 2-6: OFF SW2: 1,3,5,6: ON 2,4: OFF P7: Closed P10: Open Note: Finally, on revision A of the AD***66 board, there is the possibility ofunwanted contention on the DSP_RXEN pin. If you are using this board revision , you should cut the trace connecting DSP_RXEN on J9 to resistor bank RP13. Subsequently, you can use a short jumper cable to connect the DSP_RXEN pin to the center pin of JP93.
