Function
0: Preload Q DAC calibration reference set to 32
1: Preload Q DAC calibration reference set by user (Cal Address 1)
0: Preload I DAC calibration reference set to 32
1: Preload I DAC calibration reference set by user (Cal Address 1)
1: Select Q DAC self-calibration
1: Select I DAC self-calibration
1: Calibration clock enabled
Calibration clock divide ratio from DAC clock rate
000 = divide by 256; 001 = divide by 128 … 110 = divide by 4; 111= divide by 2
1: Calibration of Q DAC complete
1: Calibration of I DAC complete
Status of Q DAC calibration memory
00: Uncalibrated
01: Self-calibrated
10: User calibrated
Status of I DAC calibration memory
00: Uncalibrated
01: Self-calibrated
10: User calibrated
Address of static memory to be accessed
Data for static memory access
1: Clear CALSTATQ
1: Clear CALSTATI
1: Initiate device self-calibration
1: Write to static memory (calibration coefficients)
1: Read from static memory (calibration coefficients)
1: Reset Q DAC calibration coefficients to default (uncalibrated)
1: Reset I DAC calibration coefficients to default (uncalibrated)
Q datapath retimer clock select output (that is, readback after Q retimer acquires)
High indicates internal data path retimer is searching for clock relationship (device
output is not usable while this bit is high)
Edge triggered, 0 to 1 causes the retimer to reacquire the clock relationship
0: CLKMODEI/Q values computed by the two retimers and read back in CLKMODEI[1:0]
and CLKMODEQ[1:0]
1: CLKMODE values set in CLKMODEI[1:0] override both I and Q retimers
0: CLKMODEN, read only; clock phase chosen by retimer
1: CLKMODEN, read/write; value in this register sets I and Q clock phases
