QSOP Pin#

Name

Function

threshold.

Connect directly to supply for 3.3V applications (internal regulator not in use). Do not connect to power supply if

3

GND

Ground.

4

DINP

Non-inverting data input. Internally terminated with 50

Ω to V

5

DINN

Inverting data input. Internally terminated with 50

Ω to V

6

NC

No Connect. Leave Floating.

Connect directly to supply for 3.3V applications (internal regulator not in use). Do not connect to power supply if

8

JAM

Output disable. When high, data outputs are disabled (with non-inverting output held high and inverting output

held low). Connect to LOS output to disable outputs with loss of signal. Outputs are enabled when JAM is low or

floating. Internal 150 k

Ω resistor to ground.

9

LOS

collector TTL with internal 80 k

Ω pull-up resistor to V

10

ST

output is an open collector TTL with internal 80 k

Ω pull-up resistor to V

11

GND

Ground.

12

PECLN

Inverting data output (PECL).

13

PECLP

Non-inverting data output (PECL).

14

Power supply. Connect to either +5V or +3.3V.

15

NC

No Connect. Leave Floating.

16

Internal reference current for the LOS threshold. Must be connected to ground through a 12.1 k

Ω 1% resistor.
