ADC3663: How to configure the test pattern registers

Part Number: ADC3663

We are trying to enable the test pattern output on both channels with 16 bit output resolution. A custom pattern 0xaa and 0xbb is written in registers 0x14 and 0x15 and to enable test pattern 0x6C is written to the register 0x16.The output we recieve is totally different from the values written in registers 0x14 and 0x15. Please explain the correct way to configure test pattern.

  • Hi Anooja,

    Can you try to configure the device in ramp test pattern on CHA.

    This can be done using the following writes: 

    0x14  ->  0x01

    0x15  ->  0x0

    0x16  -> 0x08

    Regards, Amy
