8 / 20 page SM8707 series NIPPON PRECISION CIRCUITS INC.—8 SM8707E fXTAL = 27.0000MHz, VDD = 3.3V ± 0.3V, VSS = 0V, Ta = – 10 to + 75 °C unless otherwise noted. Parameter Symbol Pins Condition Rating Unit min typ max External input clock frequency1 1. When using an external clock input, the XTI duty should be 50% with 3.3V clock signal amplitude level. The input signal voltage should not exceed the absolute maximum rating, otherwise damage may occur. fXTI XTI Applies to external clock input use only – 27.0000 – MHz Output clock rise time2 2. The numeric values are measured values obtained using the circuit in Figure 1 and the NPC standard evaluation board. tr MO1 CL = 40 pF, transition between VOL = 0.2VDD and VOH = 0.8VDD – 2.0 – ns MO2 CL = 25 pF, transition between VOL = 0.2VDD and VOH = 0.8VDD – 2.0 – SO1, SO2, AO1, AO2 CL = 15pF, transition between VOL = 0.2VDD and VOH = 0.8VDD – 2.0 – Output clock fall time2 tf MO1 CL = 40pF, transition between VOH = 0.8VDD and VOL = 0.2VDD – 2.0 – ns MO2 CL = 25pF, transition between VOH = 0.8VDD and VOL = 0.2VDD – 2.0 – SO1, SO2, AO1, AO2 CL = 15pF, transition between VOH = 0.8VDD and VOL = 0.2VDD – 2.0 – Output clock jitter3 3.
