MT9072
9.1.5.2 Transmit AIS Operation (TAIS Pin)
The TAIS pin allows all eight framers of the MT9072 to transmit an all ones signal (AIS) at the TPOS and TNEG
output pins from the point of power-up, without the need to write any control registers. During this time the IRQ
pin is in a high impedance state. After the interface has been initialized normal operation can take place by
making TAIS high.
