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 1VP-P, 1MHz sine wave. The voltage gain (in dB) is given by GV = 20 log (VOUT / VIN).
Note 3: Input a 1VP-P, 4.43MHz sine wave. The interchannel crosstalk (in dB) is given by CT = 20 log (VOUT / VIN) + 6.
Note 4: Input 1VP-P, 1MHz and 10MHz sine waves. The frequency characteristic (in dB) is given by Gf = 20 log (VOUT (f = 10MHz) / VOUT (f = 1MHz) ).
Note 5: Input a 1VP-P, 4.43MHz sine wave. The mute level is given by CTM = 20 log (VOUT / VIN) + 6 (dB).
Note 6: Input a 1VP-P, 1MHz 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 10mVP-P.
