DAC5662EVM: Output sin wave signal voltage swing

MESH

Part Number: DAC5662EVM
Other Parts Discussed in Thread: DAC5662

Hello,

I will use DAC5662EVM to check behavior of DAC and transformer circuit.

I want to check if the output voltage swing from the J1 connector on DAC5662EVM is 0.5Vpp within the transformer band (P/N:T1-1T-KK81 0.08 to 200MHz).

Input data to DAC5662 is below and circuit of DAC5662EVM is not changed.

<DAC input>
sin wave data 0x000 to 0xFFF
sine wave frequency 100kHz to 150MHz

Regards,

Ok, it looks like you are exercising the DAC through full scale operation. No issues. Be cognizant of the transformer frequency response across the frequency range. You can use the TSW1400 pattern card if needed to generate the digital patterns if needed.

Hello, RJ Hopper

Thank you for your reply.

I will test the DAC5662EVM and onbord transformer circuit.
