AC CHARACTERISTICS
AC characteristics are specified over recommended operating conditions (TA = 0°C to
+70°C, VDD = 3.3 V ±5%).
The PM3350 only supports 5V signalling environment
Notes on Input Timing:
1. When a set-up time is specified between an input and a clock, the set-up time is
the time in nanoseconds from the 1.4 Volt point of the input to the 1.4 Volt point
of the clock.
2. When a hold time is specified between an input and a clock, the hold time is the
time in nanoseconds from the 1.4 Volt point of the clock to the 1.4 Volt point of
the input.
Notes on Output Timing:
1. Output propagation delay time is the time in nanoseconds from the 1.4 Volt point
of the reference signal to the 1.4 Volt point of the output.
2. Maximum and minimum output propagation delays are specified with a 50 pF
load on the outputs, unless otherwise noted.
3. Output tri-state delay is the time in nanoseconds from the 1.4 Volt point of the
reference signal to ±300mV of the termination voltage on the output. The test
load is 50Ω to 1.4V in parallel with 10 pF to GND.
Notes on Typical Values:
AC parameters that are shown as Typical in the following tables are tested for
functionality under typical conditions. No guarantees are implied for max or min
performance.
