7 / 12 page  CF5019 series SEIKO NPC CORPORATION —7 Switching Characteristics CF5019ALA, CF5019ALB 2.5V operation VDD = 2.25 to 2.75V, VSS = 0V, Ta = −40 to +85°C unless otherwise noted. 3V operation VDD = 2.7 to 3.6V, VSS = 0V, Ta = −40 to +85°C unless otherwise noted. Parameter Symbol Condition Rating Unit min typ max Output rise time tr1 Measurement cct 3, load cct 1, 0.1VDD to 0.9VDD CL = 15pF – 1 3 ns tr2 CL = 30pF – 2 5.5 ns Output fall time tf1 Measurement cct 3, load cct 1, 0.9VDD to 0.1VDD CL = 15pF – 1 3 ns tf2 CL = 30pF – 2 5.5 ns Output duty cycle*1 *1. The duty cycle characteristic is checked the sample chips of each production lot. Duty1 Measurement cct 3, load cct 1, VDD = 2.5V, Ta = 25°C CL = 15pF, f = 106MHz 45 – 55 % CL = 15pF, f = 125MHz 40 – 60 % Duty2 CL = 30pF, f = 70MHz 45 – 55 % Output disable delay time*2 *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 = 2.5V, Ta = 25°C, CL = 15pF – – 100 ns Output enable delay time*2 tPZL – – 100 ns Parameter Symbol Condition Rating Unit min typ max Output rise time tr1 Measurement cct 3, load cct 1, 0.1VDD to 0.9VDD CL = 15pF – 1 2.5 ns tr2 VDD = 3.0 to 3.6V CL = 30pF – 1.5 3 ns Output fall time tf1 Measurement cct 3, load cct 1, 0.9VDD to 0.1VDD CL = 15pF – 1 2.5 ns tf2 VDD = 3.0 to 3.6V CL = 30pF – 1.5 3 ns Output duty cycle*1 *1. The duty cycle characteristic is checked the sample chips of each production lot. Duty2 Measurement cct 3, load cct 1, VDD = 3.0V, Ta = 25°C, CL = 30pF, f = 125MHz 45–55 % Output disable delay time*2 *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 time*2 tPZL – – 100 ns |
