The following figure shows the hardware blocks of the receiver. In SDR and DDR modes, the data width
from the IOE is 1 and 2 bits, respectively. The deserializer includes shift registers and parallel load registers,
and sends a maximum of 10 bits to the internal logic.

DPA Block
The DPA block takes in high-speed serial data from the differential input buffer and selects one of the eight
phases that the fractional PLLs generate to sample the data. The DPA chooses a phase closest to the phase
of the serial data. The maximum phase offset between the received data and the selected phase is 1/8 UI,
which is the maximum quantization error of the DPA. The eight phases of the clock are equally divided,
offering a 45° resolution.
The following figure shows the possible phase relationships between the DPA clocks and the incoming serial
data.
