Note:
Because of the ultra-high speed of the P4C1256, care must be taken when
testing this device; an inadequate setup can cause a normal functioning part
to be rejected as faulty. Long high-inductance leads that cause supply
bounce must be avoided by bringing the V
and ground planes directly up
to the contactor fingers. A 0.01 μF high frequency capacitor is also required
between V
CC
and ground. To avoid signal reflections, proper termination
must be used; for example, a 50
test environment should be terminated
into a 50
load with 1.73V (Thevenin Voltage) at the comparator input,
and a 116
resistor must be used in series with D
OUT
to match 166
(Thevenin Resistance).
