DIG_DATAPATH_PD

Holds all digital logic (SERDES digital,

digital clock generation, and digital

datapath) in reset until clock tree is stable.

0x1

R/W

Normal operating mode.

Holds the digital logic in reset. Must be

released (set to 0) after clocks to the chip

are stable (PLL and DLL blocks are locked)

to use the digital datapath.

JESD_MODE

Sets the JESD204B mode configuration.

See Table 13 for the JESD204B supported

operating modes and compatible interpola-

tion rates. Bit 5 of this control determines

single link (set to 0) or dual link (set to 1).

Bits[4:0] set the desired JESD204B mode

according to Table 13.
