Test Circuits and Timing Waveforms
Test Circuit for A Outputs
CL includes probes and jig capacitance.
Test Circuit for B Outputs
CL includes probes and jig capacitance.
For B Port outputs, CL = 30 pF is used for
worst case edge rate.
Voltage Waveforms Pulse Duration
(Vm
= 1.5V for A Port and 1.0V for B Port)
Voltage Waveforms Setup and Hold Times
(Vm
= 1.5V for A Port and 1.0V for B Port)
Voltage Waveforms Propagation Delay Times
(A Port to B Port)
Voltage Waveforms Propagation Delay Times
(B Port to A Port)
All input pulses have the following characteristics: frequency
= 10 MHz, t
r = tf = 2 ns, ZO = 50. The outputs are measured
one at a time with one transition per measurement.
Voltage Waveforms Enable and Disable Times (A Port)
Waveform 1 is for an output with internal conditions such that the output is low except when disabled by the output control. Waveform 2 is for an output with
internal conditions such that the output is HIGH except when disabled by the output control. All input pulses have the following characteristics:
frequency
= 10 MHz, t
r = tf = 2 ns, ZO = 50. The outputs are measured one at a time with one transition per measurement.
