Alternative Switch & Jumper Configurations
Power Down mode
Both the transmitter and receiver have power down control pins. Power down
mode shuts down the internal PLL and other circuitry to minimize power
consumption. Power down control is accessed using switches SW2 and SW3 on
the evaluation board as shown on below figure. Please see datasheet for detail
on power down operation and timing.
