EVM Quick Start Guide

2EVM 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.

2.1EVM LVDS Output Mode Quick Start (Default)

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.

2.2EVM CMOS Output Mode Quick Start

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.
