1. Test condition: Rload=100Ohm between padp and padn.

2. Measurement levels are 20-80% from output voltage.

3. See figure "LLCP LVDS Output Waveform" below.

4. See figure "Output Offset Voltage imbalance waveform" below.

NOTE

Skew between Data and Strobe:

LLCP data and strobe pairs should be routed as 100 Ohm

differential pairs with matched routing length to ensure

equivalent propagation time for each differential signal.

Propagation time mismatch should be checked at receiver;

mismatched propagation delay beyond ±80ps between data and

strobe signals might exceed capabilities of on-die timing

compensation circuits and prevent correct operation of

interface.
