Dual 16-bit DAC: up to 1.25 Gsps; x2, x4 and x8 interpolating
The compensation delay time, referred to as t
cmp
in
Figure 14
, can be tuned automatically
or manually.
Automatic tuning is recommended for a high-speed LVDS data rate (> 300 MHz). The
external LVDS data and clock signals aligns the rising and falling edges. The timing
requirement is defined in
Figure 15
and in
Table 5
.
When tuning manually, the compensation delay time (t
cmp
in
Figure 14
), can be tuned as
shown in
Table 11
using bits LDCLK_DEL[3:0] of register MAN_LDCLKDEL
(see
Table 81
) and bit CAL_CNTRL of register MAIN_CNTRL (see
Table 80
).

t
sk(min)
= minimum skew time
t
sk(max)
= maximum skew time
