Modes of Operation
The device supports several data transfer modes, electrical idle mode, and several power reducing modes.
Electrical Idle Mode
In electrical idle mode, the transmitter stops toggling and maintains its common-mode voltage level. The device enters electrical idle mode when
the envelope of the incoming signal on a given channel has fallen below a programmable threshold level.
Power Reducing Modes
The Repeater supports five power-down states and one active state as shown in Table 4. The user can choose between full chip power-down,
channel based power-down, and electrical idle modes. Power reducing modes can be selected via PDB and RSTB.
