### SAWG v2.0
This is an extension of SAWG v1.0 with a 1 GSPS data rate and with board-board synchronization.

This is an extension of SAWG v1.0 with a 1 GSPS data rate. This milestone also includes board-board synchronization.
- f_rtio = f_dac_ref = 125 MHz (same as for Kasli)
- dac data rate 1.0 GSPS
- f_dac_clk = 2.0 GHz (2X interpolation)

### SAWG v2.1
__SAWG v2.1 milestone__
This is an extension of SAWG v2.0 that includes improvements in performance and gateware utilization.
- support for 4 RF channels per DAC
- spurious frequency components due to DSP: < -70 dBc at full amplitude, constant frequency
- improvements detailed in MT1
