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