Applications Information
POWER SEQUENCING AND POWERDOWN MODE
Outputs of the transmitter remain in TRI-STATE until the
power supply reaches 2V. Clock and data outputs will begin
to toggle 10 ms after V
down pin is above 1.5V. Either device may be placed into a
powerdown mode at any time by asserting the Powerdown
pin (active low). Total power dissipation for each device will
decrease to 5 µW (typical).
The transmitter input clock may be applied prior to powering
up and enabling the transmitter. The transmitter input clock
may also be applied after power up; however, the use of the
PWR DOWN pin is required as described in the Transmitter
Input Clock section. Do not power up and enable (PWR
DOWN = HIGH) the transmitter without a valid clock signal
applied to the TxCLK IN pin.

The FPD Link chipset is designed to protect itself from
accidental loss of power to either the transmitter or receiver.
If power to the transmit board is lost, the receiver clocks
(input and output) stop. The data outputs (RxOUT) retain the
states they were in when the clocks stopped. When the
receiver board loses power, the receiver inputs are con-
trolled by a failsafe bias circuitry. The LVDS inputs are
High-Z during initial power on and power off conditions.
Current is limited (5 mA per input) by the fixed current mode
drivers, thus avoiding the potential for latchup when power-
ing the device.
