High Frequency Boosting

RXFER[6:4] adjusts a boost in the 500 MHz to 2 GHz range.

all 1s. RXFER[9:0] = 111XXX1111
The frequency steps here do not follow LSB to MSB. The order of the lowest weight bit to
the highest weight bit is RXFER[5], RXFER[6] and then RXFER[4]. Hence, the boost of the
transfer function is set at low to high frequencies by the bits RXFER[6:4] = 000, 010, 100,
110, 001, 011, 101, and 111, respectively.
RXFER[9:7] also adjusts a boost in the 500 MHz to 2 GHz range.
