Type
Differential data inputs. Each input is internally terminated to
approximately VCC – 1.3V by a 50Ω resistor. AC-Couple input signals.
Tie this pin to pin 6 (VTHREF) and apply a DC voltage on pin 16
(VTHP) for signal crossing adjustment. Connect to ground if no crossing
adjustment is needed.
1.25V Reference voltage (referenced to ground) for decision threshold
adjustment.
Loss-of-Signal: asserts high when the data input amplitude falls below
the threshold set by LOS
Loss-of-Signal Level Set. A resistor from this pin to V
threshold for the data input amplitude at which LOS will be asserted.
Differential data outputs. Unused output should be terminated 50Ω-to-
VCC.
Unused pins.
/Enable: This input enables the outputs when it is LOW. Note that this
input is internally connected to a 25kΩ pull-up resistor and will default to
a logic HIGH state if left open.
Apply a DC voltage from 0 to 2.4V to adjust the signal crossing level
when pin 5 (VTHN) is tied to pin 6 (VTHREF). 1.25V sets the crossing
close to 50%. Connect to ground if no crossing adjustment is needed.
Device ground. Exposed pad must be soldered (or equivalent) to the
same potential as the ground pins.
Positive power supply. Bypass with 0.1µF||0.01µF low ESR capacitors.
0.01µF capacitors should be as close as possible to VCC pins.
