Applications Information
POWER SEQUENCING AND POWERDOWN MODE
Outputs of the transmitter remain in TRI-STATE until the pow-
er supply reaches 2V. Clock and data outputs will begin to
toggle 10 ms after V
pin is above 1.5V. Either device may be placed into a power-
down mode at any time by asserting the Powerdown pin
(active low). Total power dissipation for each device will de-
crease 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

applied to the TxCLK IN pin.
The FPD Link chipset is designed to protect itself from acci-
dental 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 controlled by a
failsafe bias circuitry. The LVDS inputs are High-Z during ini-
tial 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 powering the device.
