NOTES
1Temperature range is as follows: –40°C to +85°C.
2Measured into a 25 Ω load using a 0-1 pattern at 622 Mbps.
3When the voltage on DATAP is greater than the voltage on DATAN, the modulation current flows in the IMODP pin.
4Guaranteed by design and characterization. Not production tested.
5ICCMIN for power calculation on page 6 is the typical ICC given.
6All VCC pins should be shorted together.
Specifications subject to change without notice.
