LOS (Los of Signal) Detect Disable
Disables internal LOS monitoring and automatic muting of
RXDO[7:0] upon LOS detection. LOS is declared when
a string
of 128 consecutive zeros occur on the line. LOS condition is
cleared when the 16 or more pulse transitions is detected for
128 bit period sliding window.
"Low" = Monitor and Mute received data upon LOS declaration
"High" = Disable internal LOS monitoring

LOS or Signal Detect Input from Optical Module
Active "Low." When active, this pin will force the received data
output bus RXDO[7:0] to a logic state of ’0.’
"Low" = Forced LOS
"High" = Normal Operation

VDD3.3
PWR
15, 18, 31, 34, 47, 61
3.3V CMOS Power Supply
VDD3.3 should be isolated from the Analog VDD power supplies.
For best results, use a ferrite bead along with an internal power
plane separation. The VDDD3.3 power supply pins should have
bypass capacitors to the nearest ground.

Analog 3.3V Transmitter Power Supply
AVDD3.3_TX should be isolated from the digital power supplies.
For best results, use a ferrite bead along with an internal power
plane separation. The AVDD3.3_TX power supply pins should
have bypass capacitors to the nearest ground.
AVDD3.3_RX

Analog 3.3V Receiver Power Supply
AVDD3.3_RX should be isolated from the digital power supplies.
For best results, use a ferrite bead along with an internal power
plane separation. The AVDD3.3_RX power supply pins should
have bypass capacitors to the nearest ground.

3.3V Input/Output LVPECL Bus Power Supply
These pins require a 3.3V potential voltage for properly biasing
the Differential LVPECL input and output pins.

Transmitter Analog Ground for 3.3V Analog Power Supplies
It is recommended that all ground pins of this device be tied
together.
