Name

Description

Memory R/W

0x12

CALRSTQ

0 (default): no action.

1: clear CALSTATQ.

CALRSTI

0 (default): no action.

1: clear CALSTATI.

CALEN

0 (default): no action.

1: initiate device self-calibration.

SMEMWR

0 (default): no action.

1: write to static memory (calibration coefficients).

SMEMRD

0 (default): no action.

1: read from static memory (calibration coefficients).

UNCALQ

0 (default): no action.

1: reset Q DAC calibration coefficients to default (uncalibrated).

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).

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).

Reacquire

Edge triggered, 0 to 1 causes the retimer to reacquire the clock relationship.

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.
