I seem to have problem using the AD9361_Filter_Wizard to design a LP filter for LTE Band5 and 20MHz bandwidth.
According to the ADI 9361 register map, register 0x05 (RFPLL Divider) indicates for band 5, the divider should be set at 8. The data rate for 20MHz bandwidth is 30.72MHz. I just could not get the correct decimation rate combination for FIR and HBs. I either get "DAC*multiplier and ADC rates do not match" or "PLL rate above maximum (1430 MHz)".
What is the problem here? Any suggestion?
