8.4 Device Functional Modes
8.4.1 Power-Down Mode
The TLK2711-SP goes into power-down mode when the ENABLE pin is pulled low. In the power-down mode, the
serial transmit pins (TXN), the receive data bus pins (RXD0 to RXD15), and RKLSB goes into a high-impedance
state. In the power-down condition, the signal detection circuit draws less than 15 mW. When the TLK2711-SP is
in the power-down mode, the clock signal on the TXCLK pin must be provided if LOS functionality is needed.
