In the data sheet for the HMC596LP4 4x2 RF switch matrix, it describes 4 control signals labeled HV1, HV2, Tone1, and Tone2. It seems like these use 5V DC voltage signals to control which inputs are connected to which outputs (based on the truth table provided in the datasheet).
However based on similar products, it appears that the Tone1 and Tone2 signals are actually constant tones (at 22KHz for example) which are either present or not (0V DC) to identify a 1 or 0 in the truth table. Is this also true for the HMC596LP4 part or is it simply 4 different 5V logic signals?
If it is the former, what frequency and amplitude should the tone be for this device?
