Part Number: ADC3663

Hi,

      customer has no experience with ADC3663 and with below requirements. would you like kindly help give the register configuration?

sample frequency 40MHZ
DCLKIN 20MHZ
output formating 2-wire SLVDS,
 with complex decimation (16bit I +16bit Q),
two's complement
Decimation Filter 2
FCLK source DDC

    Hi Ken,

    If the customer is new to using the ADC3663, please point them to the ADC3663EVM user guide for reference: 

    https://www.ti.com/lit/ug/sbau366/sbau366.pdf?ts=1669142607407&ref_url=https%253A%252F%252Fwww.ti.com%252Ftool%252FADC3663EVM 

    Additionally, the customer can download our EVM GUI below and change settings to export their desired register writes by selecting 'save config file':

    https://www.ti.com/tool/ADC3663EVM 

    I set the GUI with the parameters described above and saved the config file with the register writes. By default, the output data formatting is two's complement. However, the customer does not mention what they would like to use for the a NCO value for complex mixing. I also assumed they wanted to use 16 bit mode. 

    Regards, Amy

    Hi Ken,

    In any situation where a discrepancy occurs between our GUI and a private register in the datasheet, we advise to stick with the value performed by our GUI.

       i has ADC3663 EVM +LVDS FPGA Interposer Card,without TSW1400EVM. Can I  export the register configuration value by "ADC35XX EVM GUI'? I can't find " 'save config file" button in "ADC35XX EVM GUI".

    Ken,

    You can export the registers using the save log button. This saves all text in the command window, including the register sequence which is written to the device. You do not need the TSW1400EVM to save the register sequence. You will need the TSW1400EVM to take any data however.

    Regards
