11.1 Additional dynamic characteristics

[1]

Adjust input voltage Vis to 0 dBm level (0 dBm = 1 mW into 600 ).

[2]

Adjust input voltage Vis to 0 dBm level at Vos for 1 MHz (0 dBm = 1 mW into 50 ).

Table 12.

Additional dynamic characteristics

Recommended conditions and typical values; GND = 0 V; Tamb =25 C; CL =50 pF.

Vis is the input voltage at pins nYn or nZ, whichever is assigned as an input.

Vos is the output voltage at pins nYn or nZ, whichever is assigned as an output.
