See “Jitter Attenuator” on page 11.
Equalizer Control Pins - Hardware Mode
Equalizer Control Input pin 4
Equalizer Control Input pin 3
Equalizer Control Input pin 2
Equalizer Control Input pin 1
Equalizer Control Input pin 0
Pins EQC[4:0] select the Receive Equalizer and Transmitter Line Build Out.
See “Alarm Function//Redundancy Support” on page 13.
NOTE: Internally pulled “Low” with a 50kΩ resistor.
Interrupt Output - Host Mode
This pin goes “Low” to indicate an alarm condition has occurred within the
device. Interrupt generation can be globally disabled by setting the GIE bit to
"0" in the command control register.
Transmitter Transformer Ratio Select - Hardware mode
The function of this pin is to select the transmitter transformer ratio. See
“Alarm Function//Redundancy Support” on page 13.
NOTE: This pin is an open drain output and requires an external 10kΩ pull-
up resistor.
