The high speed performance for the die version of ADN2847 can be achieved when using the bonding diagram shown in Figure 3.
3
Measured into a 25
W
load using a 11110000 pattern at 2.5 Gbps.
4
When the voltage on DATAP is greater than the voltage on DATAN, the modulation current flows in the IMODP pin.
5
Guaranteed by design and characterization. Not production tested.
6
IDTONE may cause eye distortion.

NOTES
1
Stresses above those listed under Absolute Maximum Ratings may cause perma-
nent damage to the device. This is a stress rating only; functional operation of the
device at these or any other conditions above those listed in the operational
sections of this specification is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability.

JA
is defined when part is soldered on a 4-layer board.
CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection. Although the
ADN2847 features proprietary ESD protection circuitry, permanent damage may occur on devices
subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended
to avoid performance degradation or loss of functionality.
