Register Address Bit Name Description
Memory R/W 0x12 7 CALRSTQ 0 (default): no action.
1: clear CALSTATQ.
6 CALRSTI 0 (default): no action.
1: clear CALSTATI.
4 CALEN 0 (default): no action.
1: initiate device self-calibration.
3 SMEMWR 0 (default): no action.
1: write to static memory (calibration coefficients).
2 SMEMRD 0 (default): no action.
1: read from static memory (calibration coefficients).
1 UNCALQ 0 (default): no action.
1: reset Q DAC calibration coefficients to default (uncalibrated).
0 UNCALI 0 (default): no action.
1: reset I DAC calibration coefficients to default (uncalibrated).
CLKMODE 0x14 7:6 CLKMODEQ[1:0]
Depending on the CLKMODEN bit setting, these two bits reflect the phase
relationship between DCLKIO and CLKIN, as described in Table 16.
If CLKMODEN = 0, read only; reports the clock phase chosen by the retimer.
If CLKMODEN = 1, read/write; value in this register sets Q clock phases; force if
needed to better synchronize the DACs (see the Retimer section).
4 Searching Data path retimer status bit.
0 (default): clock relationship established.
1: indicates that the internal data path retimer is searching for clock relationship
(device output is not usable while this bit is high).
3 Reacquire Edge triggered, 0 to 1 causes the retimer to reacquire the clock relationship.
2 CLKMODEN
0 (default): CLKMODEI/CLKMODEQ 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.
1:0 CLKMODEI[1:0]
Depending on CLKMODEN bit setting, these two bits reflect the phase
relationship between DCLKIO and CLKIN as described in Table 16.
If CLKMODEN = 0, read only; reports the clock phase chosen by the retimer.
If CLKMODEN = 1, read/write; value in this register sets I clock phases; force if
needed to better synchronize the DACs (see the Retimer section).
Version 0x1F 7:0 Version[7:0]
Hardware version of the device. This register is set to 0x03 for the latest version of
the device.
