Loop Closure Threshold.
Loop closure detection threshold. This register defines the upper bounds threshold if hys-
teresis is enabled (direct Register 108, bit 0). The range is 0–80 mA in 1.27 mA steps.
Ring Trip Threshold.
Ring trip detection threshold during ringing.
Common Mode Minimum Threshold for Speed-Up.
This register defines the negative common mode voltage threshold. Exceeding this
threshold enables a wider bandwidth of dc linefeed control for faster settling times. The
range is 0–23.625 V in 0.375 V steps.
Common Mode Maximum Threshold for Speed-Up.
This register defines the positive common mode voltage threshold. Exceeding this
threshold enables a wider bandwidth of dc linefeed control for faster settling times. The
range is 0–23.625 V in 0.375 V steps.
Power Alarm Threshold for Transistors Q1 and Q2.
Power Alarm Threshold for Transistors Q3 and Q4.
Power Alarm Threshold for Transistors Q5 and Q6.
Loop Closure Filter Coefficient.
Ring Trip Filter Coefficient.
Thermal Low Pass Filter Pole for Transistors Q1 and Q2.
Thermal Low Pass Filter Pole for Transistors Q3 and Q4.
Thermal Low Pass Filter Pole for Transistors Q5 and Q6.
Common Mode Bias Adjust During Ringing.
Recommended value of 0 decimal.
DC-DC Converter V
This register sets the overhead voltage, V
When the VOV bit = 0 (direct Register 66, bit 4), V
(VMIND = 0 to 6h). When the VOV bit = 1, V
(VMIND = 0 to 9h).
Reserved.
Loop Closure Threshold—Lower Bound.
This register defines the lower threshold for loop closure hysteresis, which is enabled in
bit 0 of direct Register 108. The range is 0–80 mA in 1.27 mA steps.
