Dual 16-bit DAC: up to 1.25 Gsps; x2, x4 and x8 interpolating
10.4.2
Input port mapping
Inverting the order of the LSB and the MSB of the LVDS bus using bit WORD_SWAP in
register LD_CNTRL (see
Table 88
) also simplifies the design of the PCB (see
Table 9
).
Table 9.
Internal LVDS bus
10.4.3
Input port swapping
The LVDS DDR receiver block internally maps the incoming LVDS data bus into two
buses with a single data rate (
Figure 7
).
These two buses can be swapped internally using bit LDAB_SWAP of register
LD_CNTRL (see
Table 88
and
Figure 8
).
