(1)
Typical values are given for VDDIO = 1.8V and VDD = VDDA = 1.8V and TA = 25°C.
(2)
1 UI is the serial data MD pulse width = 1 / 8xPCLK (3 MD lanes), 1 UI is the serial data MD pulse width = 1 / 12xPCLK (2 MD lanes)
(3)
This is a functional parameter and is specified by design or characterization.
(4)
Enable Time is a complete MPL start up comprised of t0 + t1 + t2 + t3 + t4.
(5)
Specified functionally by the IDDZ parameter. See also Figure 10.
