PARAMETER MIN NOM MAX UNIT
t1(3) SCLK cycle time VDD = 2.7 V to 3.6 V 50 ns
VDD = 3.6 V to 5.5 V 33
t2 SCLK HIGH time VDD = 2.7 V to 3.6 V 13 ns
VDD = 3.6 V to 5.5 V 13
t3 SCLK LOW time VDD = 2.7 V to 3.6 V 22.5 ns

t7 SCLK falling edge to SYNC rising edge VDD = 2.7 V to 3.6 V 0 ns
VDD = 3.6 V to 5.5 V 0
t8 Minimum SYNC HIGH time VDD = 2.7 V to 3.6 V 50 ns
VDD = 3.6 V to 5.5 V 33
t9 24th SCLK falling edge to SYNC falling edge VDD = 2.7 V to 3.6 V 100 ns
VDD = 3.6 V to 5.5 V 100
t10 SYNC rising edge to 24th SCLK falling edge
(for successful SYNC interrupt)		 VDD = 2.7 V to 3.6 V 15 ns

(1) All input signals are specified with tR = tF = 3 ns (10% to 90% of VDD) and timed from a voltage level of (VIL + VIH) / 2.
(2) See Figure 1.
(3) Maximum SCLK frequency is 3 0MHz at VDD = 3.6 V to 5.5 V and 20 MHz at VDD = 2.7 V to 3.6 V.
