Pin Description
Pin Number
Pin Name
Type
Pin Function
1
DIN
Data Input
True data input.
4
/DIN
Data Input
Complementary data input.
5
VTHN
DC Input
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.
6
VTHREF
1.25V Reference voltage (referenced to ground) for decision
threshold adjustment.
7
LOS
Open-collector TTL
output
Loss-of-Signal: asserts high when the data input amplitude falls
below the threshold set by LOSLVL.
9
/DOUT
CML Output
Complementary data output.
12
DOUT
CML Output
True data output.
14
LOSLVL
Input
Loss-of-Signal Level Set. A resistor from this pin to VCC sets the
threshold for the data input amplitude at which LOS will be
asserted.
15
/EN
TTL Input: Default is
HIGH.
/Enable: This input enables the outputs when it is LOW. Note
that this input is internally connected to a 25k pull-up resistor
and will default to a logic HIGH state if left open.
16
VTHP
DC Input
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.
2, 3, 10, 11
GND
Ground
Device ground.
8, 13
VCC
Power Supply
Positive power supply.
