0-3
Pseudo AUI Data Output
Input
Single-ended receiver. Data input from the IMR2 device.
PDI
Pseudo AUI Data Input
Output
Single-ended output driver. Data output to the
IMR2 device.
0-3

REXT
External Resistor
Input
REXT must be tied to AV
resistor.This provides the current reference for all inter-
nal analog functions.
AV
DD
Analog Power
Power Pin
These pins supply +5-V power to the analog portion of
the device. These pins should be decoupled and kept
separate from the digital power plane.
DD

AV
Analog Ground
Ground Pin
These pins provide the ground reference for the analog
portions of the QuIET circuitry.
SS
Digital
SDATA
Serial Data
Input/Output
Transfers command and status data between the
QuIET device and the IMR2 chip.
DIR
Direction
Input
Selects the direction of command data and status data
transfer between the QuIET device and the IMR2 chip.
RST
Reset
Input, Active Low
Resets the internal registers of the QuIET device.
CLK
Clock
Input
20-Mhz clock signal. The clock signal should be the
same one that is used by all IMR2 devices connected
to the QuIET chip.
TEST
Input, Active High
Reserved for factory use only. This pin does have an
internal pull-down, but should be tied LOW for
normal operation.
DV
Digital Power
Power Pin
These pins supply +5-V power to the digital portion of
the device. These pins should be decoupled and kept
separate from the analog power plane.
DD
DV
Digital Ground
Ground Pin
These pins provide the ground reference for the digital
portions of the QuIET circuitry.
SS
Note:
All digital I/O pins are CMOS and TTL compatible.
