1. One UI is defined as the normalized mean time between one edge and the following edge of the clock.
2. Taken from the 0 V crossing point with the DLL off.
3. Also defined with a maximum loading capacitance of 10 pF on any pin. The loading capacitance may also need to be less for higher bitrates
so the rise and fall times do not exceed the maximum 0.3 UI.
4. The absolute mean skew between the Clock lane and any Data Lane in the same PHY between any edges.
5. The absolute skew between any Clock in one PHY and any Data lane in any other PHY between any edges.
6. Differential skew is defined as the skew between complementary outputs. It is measured as the absolute time between the two
complementary edges at mean VCM point. Note that differential skew also is related to the DVCM_AC spec which also must not be exceeded.
HiVCM Electrical Specifications
The HiSPi 2.0 specification also defines an alternative
signaling level mode called HiVCM. Both V
OD
and V
CM
are
still scalable with V
DD
_HiSPi_TX, but with
V
DD
_HiSPi_TX nominal set to 1.8 V the common-mode is
elevated to around 0.9 V.
