EVM Quick Start Guide
The ADC has two basic modes of output operation, ensuring compatibility in a broad range of systems.
Follow the steps below to get the EVM operating quickly with the ADC in either DDR LVDS output mode
or CMOS output mode.
Note: Follow the steps in the listed order; not doing so could result in improper operation.
1. Ensure a jumper is installed between pins 1 and 2 on JP2.
2. Ensure DIP switch SW1, switch 2 is set to LVDS.
3. Ensure DIP switch SW1, switch 8 is set to PARALLEL.
4. Use a regulated power supply to provide 3.3 VDC to the ADC at J11 and J15, with the corresponding
returns connected to J9 and J16.
5. Use a regulated power supply to provide a 5-VDC input to J14, while connecting the return to J17.
6. Provide a filtered, low-phase-noise, sinusoidal 1.5-Vrms, 170-MHz clock to J7.
7. Provide a filtered, sinusoidal analog input to J3.
8. Using a logic analyzer and
Table 3 in this manual, monitor the ADC output on J4.
1. Ensure a jumper is installed between pins 2 and 3 on JP2.
2. Ensure DIP switch SW1, switch 2 is set to CMOS.
3. Ensure DIP switch SW1, switch 8 is set to PARALLEL.
4. Use a regulated power supply to provide 3.3 VDC to the ADC at J11 and J15, with the corresponding
returns connected to J9 and J16.
5. Use a regulated power supply to provide a 5-VDC input to J14, while connecting the return to J17.
6. Provide a low-phase-noise, sinusoidal 1.5-Vrms, 170-MHz clock to J7.
7. Provide a filtered sinusoidal analog input to J3.
8. Briefly depress S1, which resets the EVM.
9. Using a logic analyzer and
Table 3 in this manual, monitor the ADC output on J4.
