Sets the attenuation level of the transmitted signal in 1 dB
steps. The default (D3-D0=0100) is for a transmit level of
–10 dBm0. The total range is 16 dB.

Gain Boost
(18 dB)
1
Boost is in the path. This boost does not change
reference levels. It is used to extend dynamic range by
compensating for internally generated noise when
receiving weak signals. The receive level detect signal
and knowledge of the hybrid and transmit attenuator
setting will determine when boost should be enabled.

TXBAUD
CLK
TXBAUD clock is the transmit baud-synchronous clock that can be used to
synchronize the input of arbitrary quad/di-bit patterns. The rising edge of
TXBAUD signals the latching of a baud-worth of data internally. Synchronous
data to be entered via the TXDALT bit, CR3 bit D7, should have data
transitions that start 1/2 bit period delayed from the TXBAUD clock edges.
D5
RXUNDSCR
DATA
This bit outputs the data received before going to the descrambler. This is
useful for sending special unscrambled patterns that can be used for signaling.
