/Enable: This input enables the outputs when LOW. Internally
connected to a 25kΩ pull-up resistor and will default to a logic
HIGH state if left open.
Differential data inputs. Each input is internally terminated to the
VREF pin by a 50Ω resistor.
Reference Voltage: Place 0.1uF capacitor to Vcc to help
stabilize LOSLVL
Loss-of-Signal Level Set. A resistor from this pin to V
threshold for the data input amplitude at which LOS will be
asserted.
Device ground. Exposed pad must be connected to PCB
ground plane.
Loss-of-Signal: asserts high when the data input amplitude falls
below the threshold set by LOS
Differential data outputs. Unused output should be terminated
50Ω to VCC.
Positive power supply. . Bypass with a 0.1uF || 0.01uF low ESR
capacitor as close to VCC pin as possible.
