Power-Up / Power-Down Operation Truth Tables
The outputs of the transmitter remain in the High-Impedance state until the power supply reaches 2V. Table 2 shows
the operation of the transmitter during power-up and power-down and operation of the /PwrDn pin.

The outputs of the transmitter or receiver remain in a high-impedance state until V
TxCLKOut± settles at a free-running frequency when the part is powered up, /PwrDn is HIGH, and the TxCLKIn
is a steady logic level (LOW / HIGH / High-Impedance).
If the input is terminated and un-driven (high-impedance) or shorted or open (fail-safe condition).
For /PwrDn or fail-safe condition, the RxCLKOut pin goes LOW for panel link devices and HIGH for channel link
devices.
Shorted means (± inputs are shorted to each other, or ± inputs are shorted to each other and ground or V
either ± inputs are shorted to ground or V
in the valid range (greater than 100mV) and V
recognized and the part responds normally.
