CALMEM
[5:4]
O
00
2-bit SMEM contents and calibration status indicator.
00: uncalibrated; SMEM contains default values (63).
01: self-calibrated; SMEM contains values from self-calibration.
10: factory-calibrated; SMEM values are transferred from FMEM.
11: user-calibrated; SMEM contains user-entered values.
CALCLK
[2:0]
I
000
3-bit self-calibration clock divider ratio. Affects time available for algorithm settling. Each
000: self-calibration clock is DAC clock/4096 (maximum self-calibration settling time for
highest linearity accuracy).
001,010,011: self-calibration clock is DAC clock/2048,1024,512.
100,101,110: self-calibration clock is DAC clock/256,128,64.
111: self-calibration clock is DAC clock/32 (minimum self-calibration settling time for
fastest algorithm completion).
