Part Number: TSW1400EVM

I bought the tsw1400 and adc3423 board and connected it like a picture

I ran it using HSDC (v5.0) software.

However, the test has failed because of the message like the picture.

The problem seems to be that USER_LED3 is not activated.

How can I activate USER_LED3?

Please help me

Leejh,

This error usually occurs when the TSW1400 is not receiving a valid clock. Can you double check the input clock is at 800KHz and at the correct amplitude called out in the ADC34xx User's Guide. Make sure both boards are provided with at least 3A power supplies.

Regards,

Jim

Thanks for the answer.

I have additional questions.

Need to input external clock to ADC3423 board?

If an external clock is input to the ADC3423 board, how should it be input?

Thank you

Connect a 80Msps clock (or lower) to SMA J9 with a power of at least 10dBm. See section 1.4 and figure 7 of the attached ADC3423EVM User's Guide.

Regards,

Jim
