UG-570
Control Output 4 (CH1 Sm ADC Ovrg)
This signal transitions high if a small ADC overload occurs.
The signal will stay high until the gain changes. After a gain
change, the signal transitions low even if the ADC overload still
occurs because the gain control holds the ADC detect in reset
until the Peak Wait Time counter expires. If an overload still
occurs, this control output will again transition high.
Control Output 3 (CH2 Low Power)
Same as Control Output 7 but applies to Rx2.
Control Output 2 (CH2 Lg LMT Ovrg)
Same as Control Output 6 but applies to Rx2.
Control Output 1 (CH2 Lg ADC Ovrg)
Same as Control Output 5 but applies to Rx2.
Control Output 0 (CH2 Sm ADC Ovrg)
Same as Control Output 4 but applies to Rx2.

0x035 = 0x04 (Rx GAIN CONTROL)

Control Output 7 Through Control Output 3 (CH2 Rx
Gain [6:2])
These control outputs represent the most significant 5 bits of
the gain index pointer for Rx2. For a split table, these bits
represent the most significant 5 bits of the LMT gain index.
Control Output 2 (CH2 Lg LMT Ovrg)
See 0x035 = 0x03 Control Output 2.
Control Output 1 (CH2 Lg ADC Ovrg)
See 0x035 = 0x03 Control Output 1.
Control Output 0 (CH2 Gain Lock)
Applies only to fast AGC mode. This signal is high if the AGC
locks the gain and low otherwise.

0x035 = 0x05 (Rx GAIN CONTROL)

Control Output 7 (CH2 Gain Change)
Normally low. Pulses high when the Rx2 gain changes. The

the pulse. For the standard LTE 10 MHz profile, the duration is
approximately 30 ns.
Control Output 6 (CH1 Gain Change)
Same as Control Output 7 but applies to Rx1.
Control Output 5 (CH2 Low Power)
See 0x035 = 0x03 Control Output 3.
Control Output 4 (CH2 Lg LMT Ovrg)
See 0x035 = 0x03 Control Output 2.
Control Output 3 (CH2 Lg ADC Ovrg)
See 0x035 = 0x03 Control Output 1.
Control Output 2 (CH2 Gain Lock)
Same as 0x035 = 0x04 Control Output 0.

Rev. A
Control Output 1 (CH2 Energy Lost)
This signal is normally low and applies only to the fast AGC. It
transitions high when the energy lost condition occurs and
stays high as long as the condition is true.
Control Output 0 (CH2 Stronger Signal)
This signal is normally low and applies only to the fast AGC. It
transitions high when the stronger signal condition occurs and
stays high as long as the condition is true.

0x035 = 0x06 (Rx GAIN CONTROL)

Control Output 7 (CH1 ADC Low Power)
See 0x035 = 0x03 Control Output 7.
Control Output 6 (CH1 Lg LMT Ovrg)
See 0x035 = 0x03 Control Output 6.
Control Output 5 (CH1 Lg ADC Ovrg)
See 0x035 = 0x03 Control Output 5.
Control Output 4 Through Control Output 0 (CH1 Rx
Gain[6:2])
Same as 0x035 = 0x04 Control Output 7 Through Control
Output 3 but applies to Rx1.

0x035 = 0x07 (Rx GAIN CONTROL)

Control Output 7 (CH1 ADC Low Power)
See 0x035 = 0x03 Control Output 7.
Control Output 6 (CH1 Lg LMT Ovrg)
See 0x035 = 0x03 Control Output 6.
Control Output 5 (CH1 Lg ADC Ovrg)
See 0x035 = 0x03 Control Output 5.
Control Output 4 (CH1 Sm ADC Ovrg)
See 0x035 = 0x03 Control Output 4.
Control Output 3 Through Control Output 1 (CH1 AGC
SM[2:0])
These control outputs correspond to the slow and fast AGC
state machines. Note that in slow AGC mode, there are only 4
states (0 through 3) so the MSB will not go high in this mode.
Control Output 0 (CH1 Gain Lock)
Same as 0x035 = 0x04 Control Output 0 but applies to Rx1.

0x035 = 0x08 (Rx GAIN CONTROL)

Control Output 7 (CH1 Stronger Signal)
Same as 0x035 = 0x05 Control Output 0 but applies to Rx1.
Control Output 6 (CH1 Gain Lock)
See 0x035 = 0x07 Control Output 0.
Control Output 5 (CH1 Energy Lost)
Same as 0x035 = 0x05 Control Output 1 but applies to Rx1.
Control Output 4 (CH1 Gain Change)
See 0x035 = 0x05 Control Output 6.
