A.

The input pulse is supplied by a generator having the following characteristics: PRR ≤ 50 kHz, 50% duty cycle, tr ≤ 3 ns, tf ≤ 3ns, ZO =

50 Ω. At the input, 50 Ω resistor is required to terminate Input Generator signal. It is not needed in actual application.

B.

CL = 15 pF and includes instrumentation and fixture capacitance within ±20%.

For optimized CMTI performance, a 0.1 μF + 1 μF decoupling capacitor should be placed close to VCC1 and VCC2. Please see Section

11.2 for capacitor placement details. A recommended 0.1μF capacitor is LLL185R71A104MA11L (CAP CER 0.1UF 10V X7R 0306 - LW

Reversed Low ESL Chip Ceramic Capacitors) or equivalent.
