NOTES

1Temperature range: –40

∞C to +85∞C.

2The high speed performance for the die version of ADN2847 can be achieved when using the bonding diagram shown in Figure 3.

3Measured into a 25

W load using a 11110000 pattern at 2.5 Gbps.

4When the voltage on DATAP is greater than the voltage on DATAN, the modulation current flows in the IMODP pin.

5Guaranteed by design and characterization. Not production tested.

6IDTONE may cause eye distortion.

7I

CCMIN for power calculation on page 8 is the typical I CC given.

8All V

CC pins should be shorted together.

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.

2 Power consumption formulae are provided on page 8.

3

qJA 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.
