Anywhere is possible.
Note 1: Connect a distortion meter to the output, and input a f = 1kHz sine wave. Adjust the input level until the output distortion is 0.5%.
This output voltage at this time is the maximum output level Vom (VP-P).
Note 2: Input a f = 1MHz, VIN = 1VP-P sine wave. The voltage gain is given by GV = 20 log (VOUT / VIN).
Note 3: Input a f = 4.43MHz, VIN = 1VP-P sine wave. The interchannel crosstalk is given by CT = 20 log (VOUT / VIN).
Note 4: Input f = 1MHz and 10MHz, VIN = 1VP-P sine waves. The frequency characteristic is given by Gf = 20 log (VOUT (f = 10MHz) / VOUT (f = 1MHz)).
Note 5: Input a f = 1MHz, VIN = 1VP-P sine wave. Reduce the CTL pin voltage from VCC. The CTL pin switching level (VTH) is the CTL pin voltage at which
the VOUT level drops below 20mVP-P.
Note 6: Input a f = 1MHz, VIN = 1VP-P sine wave. Increase the CTL pin voltage from 0V. The CTL pin switching level (VTH) is the CTL pin voltage at which
the VOUT level goes below 1.0VDC
