LOS (Los of Signal) Detect Disable
Disables internal LOS monitoring and automatic muting of
RXDO[7:0] upon LOS detection (according to gating shown in
Figure 7.) 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 (see Figure 7 for logic
operation.)

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

VDD3.3
PWR
2,28,31,49,54,58,76,99
3.3V CMOS Power Supply
VDD3.3 should be isolated from the analog VDD power supplies.
Use a ferrite bead along with an internal power plane separation.
The VDD3.3 power supply pins should have bypass capacitors to
the nearest ground. For best results, refer to Application notes
about general board layout guidelines.

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
PWR
67,,68,69
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.
VDD_LVPECL
PWR

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.
