hi, i want to gernerate a BPSK signal with the carrier frequency 200MHz and the data rate 1Kbps,how can I set and connect the AD9910 evaluation board? Thanks in advance!
Using the AD9910 evaluation software, configure the frequency and phase offset on each profile. In this application, we will be needing two profiles wherein each has the same frequency but different phase offsets(0 deg and 180 deg). Let's just say we will use P0 and P1 for convenience. When the configuration are set, it is recommended to remove R35 and R36. After then, you can use a complimentary signal on both P0 and P1 that has a data rate that you intend to use.
I just want to add something. You can actually use only on profile pin but ensure that you are setting the values on the right profiles. Example, if you would use only pin P0 (P1 and P2 are pulled down), P0 = 0 is b000, while P0 = 1 is b001 which represents profiles 0 and 1. The digital signal that will be fed into the pin should be synchronous with the SYNC_CLK and it should be in compliance with 3.3 V logic.
