1. All input signals are specified with tr = tr = 5 ns (10% to 90% of 5 V) and timed froma voltage level of 1.6 V.
2. Serial timng is measured with a 4.7 k
pull-up resistor on SDATA and SSTRB and a 2 k
pull-up resistor on SCLK. The
capacitance on all three outputs is 35 pF.
3. SCLK mark/space ration (measured froma voltage level of 1.6 V) is 40/60 to 60/40.
4. SDATA will drive higher capacitive loads, but this will add to t
12
since it increases the external RC time constant (4.7k
/C
L
) and
hence, the time to reach 2.4 V.
