Our customer will plan to design the FMCW radar w/ ADF4169.
Using the function "Delay Between Ramps" and "Fast Ramp Mode" of ADF4169,
can we control like the "Digital Ramp Generator (DRG) of DDS" ?
It is only used "FSK or PSK mode", and "External Control of Ramp Steps mode" ?
Controlling the toggling the TXDATA pin,can not we use at "Fast Ramp Mode" ?
We expect the following behavior,
using the external trigger signal (TXdata pin ?),
lower limit > start ramp up ( w/ external trigger ? ) > upper limit > ramp down > stop lower limit > start ramp up ( w/ external trigger ? ) > repeat ...
