Notes
1. Short rise and fall times improve the tolerance of clocks to signal and supply noise.
2. If MCLK24 = 1 then T_m = -f-_M-----_C--4-_L---_K---_I--_N-- else T_m = -f-_M-----_C--2-_L---_K---_I--_N-- .
3. To allow for the effects of load capacitance the timing values should be de-rated by 0.5 ns/pF.
4. For maximum clock signal load of 25 pF.
5. L3DATA to L3CLK HIGH.
6. L3DATA to L3MODE HIGH.
