6 / 10 page  CF5017 series SEIKO NPC CORPORATION —6 Switching Characteristics 3V operation (CF5017ALA, ALB, ALC, ALD) VDD = 2.7 to 3.6V, VSS = 0V, Ta = −40 to +85°C unless otherwise noted. 5V operation (CF5017ALA, ALB, ALC) VDD = 4.5 to 5.5V, VSS = 0V, Ta = −40 to +85°C unless otherwise noted. Current consumption and Output waveform with NPC’s standard crystal Parameter Symbol Condition Rating Unit min typ max Output rise time tr Measurement cct 3, load cct 1, 0.1VDD to 0.9VDD , CL = 30pF – 2.5 5 ns Output fall time tf Measurement cct 3, load cct 1, 0.9VDD to 0.1VDD , CL = 30pF – 2.5 5 ns Output duty cycle1 1. The duty cycle characteristic is checked the sample chips of each production lot. Duty Measurement cct 3, load cct 1, VDD = 3.0V, Ta = 25°C, f = 80MHz, CL = 30pF 45–55 % Output disable delay time2 2. Oscillator stop function is built-in. When INHN goes LOW, normal output stops. When INHN goes HIGH, normal output is not resumed until after the oscillator start-up time has elapsed. tPLZ Measurement cct 6, load cct 1, VDD = 3.0V, Ta = 25°C, CL = 15pF – – 100 ns Output enable delay time2 tPZL – – 100 ns Parameter Symbol Condition Rating Unit min typ max Output rise time tr Measurement cct 3, load cct 1, 0.1VDD to 0.9VDD , CL = 30pF – 2 4 ns Output fall time tf Measurement cct 3, load cct 1, 0.9VDD to 0.1VDD , CL = 30pF – 2 4 ns Output duty cycle1 1. The duty cycle characteristic is checked the sample chips of each production lot. Duty Measurement cct 3, load cct 1, VDD = 5.0V, Ta = 25°C, f = 80MHz, CL = 30pF 45–55 % Output disable delay time2 2. Oscillator stop function is built-in. When INHN goes LOW, normal output stops. When INHN goes HIGH, normal output is not resumed until after the oscillator start-up time has elapsed. tPLZ Measurement cct 6, load cct 1, VDD = 5.0V, Ta = 25°C, CL = 15pF – – 100 ns Output enable delay time2 tPZL – – 100 ns f [MHz] R [ Ω] L [mH] Ca [fF] Cb [pF] 30 18.62 16.24 1.733 5.337 40 20.53 11.34 1.396 3.989 50 22.17 7.40 1.370 4.105 60 15.37 3.83 1.836 5.191 70 25.42 4.18 1.254 5.170 85 20.58 5.22 0.671 4.965 L Ca R Cb |
