Other Parts Discussed in Thread: AWR1642
Hi,
I am currently working with three AWR1642's in a network (multistatic mode). Right now, they are hardware synchronized together in the network. I have worked hard to software synchronize them, but with clock drift among the radars (inaccuracy in clocks during test), I have not been able to solve this (recommendations?).
Recently, I found a possible solution through a fellow lab at MIT (called AirShare, documentation attached). In short, AirShare has two components: a clock emitter and a clock recipient. The emitter transmits two tones, f1 and f2, that are separated by the desired clock frequency. The AirShre implementation has a bandpass filter that creates a desired input clock frequency of 10 MHz. Will a 10 MHz external clock frequency function properly as an external clock input to the AWR?
On the AWR1642 device documentation, it denotes the external clock should be connected to CLKP pin at 40 MHz. Documentation below.
Any help would be greatly appreciated... thank you!
George
