Descriptions
DO+/RI+
14, 16, 19, 21
I/O
True Bus LVDS Driver Outputs and Receiver Inputs.
DO−/RI−
13, 15, 18, 20
I/O
Complimentary Bus LVDS Driver Outputs and Receiver Inputs.
D
IN
35, 37, 40, 42
I
LVTTL Driver Input. No pull up or pull down is attached to this pin
RO
36, 38, 41, 43
O
LVTTL Receiver Output.
RE12
29
I
Receiver Enable LVTTL Input (Active Low). This pin, when low,
configures receiver outputs, RO1 and RO2 active. When this pin is
high, RO1 and RO2 are TRI-STATE. If this pin is floating, a weak
current source to V
CC
causes RO1 and RO2 to be TRI-STATE
RE34
5
I
Receiver Enable LVTTL Input (Active Low). This pin, when low,
configures receiver outputs, RO3 and RO4 active. When this pin is
high, RO3 and RO4 are TRI-STATE. If this pin is floating, a weak
current source to V
CC
causes RO3 and RO4 to be TRI-STATE
DE12
26
I
Driver Enable LVTTL Input (Active High). This pin, when high,
configures driver outputs, DO1+/RIN1+, DO1−/RIN1− and
DO2+/RIN2+, DO2−/RIN2− active. When this pin is low, driver outputs
1 and 2 are TRI-STATE. If this pin is floating, a weak current source
to V
CC
causes driver outputs 1 and 2 to be active
DE34
8
I
Driver Enable LVTTL Input (Active High). This pin, when high,
configures driver outputs, DO3+/RIN3+, DO3−/RIN3− and
DO4+/RIN4+, DO4−/RIN4− active. When this pin is low, driver outputs
3 and 4 are TRI-STATE. If this pin is floating, a weak current source
to V
CC
causes driver outputs 3 and 4 to be active
GND
4, 28, 31, 39
Ground
Ground for digital circuitry (must connect to GND on PC board). These
pins connected internally.
V
CC
3, 6, 30
Power
V
CC
for digital circuitry (must connect to V
CC
on PC board). These
pins connected internally.
AGND
9, 17, 25
Ground
Ground for analog circuitry (must connect to GND on PC board).
These pins connected internally.
AV
CC
7, 10, 22, 27
Power
Analog V
CC
(must connect to V
CC
on PC board). These pins
connected internally.
NC
1, 2, 11, 12, 23, 24,
32, 33, 34, 44
N/A
Reserved for future use, leave open circuit.
DAP
GND
Must connect to GND plane through vias to achieve the theta ja
specified under Absolute Maximum Ratings. The DAP (die attach pad)
is the heat transfer material that is centered on the bottom of the LLP
package. Refer to application note AN-1187 for attachment details.
