The parallel input has two input modes: single- and
double-rate input. In single-input mode, LATCH A stores
data from DIN_ every PCLKIN cycle
data from LATCH A is then sent to the scrambler for
serialization
from 6.25MHz to 50MHz.

In double-input mode, LATCH B stores two input words

as a combined word. The MAX9272 deserializer outputs
the combined word (single-output mode) or two half-sized
words (double-output mode). The serializer/deserializer
use pixel clock rates from 33.3MHz to 100MHz for 11-bit,
double-input mode and 25MHz to 75MHz for 15-bit,
double-input mode. See
