Hi, Please tell me about the DS110DF410 mute condition.
I understand that mute means "no differential voltage" at the output. When you monitor the output level before the AC coupling cap, following voltage was measured on each TXPn/TXNn pins.
1) Around 1.8V : No signal input, output mute by default
2) Around 1.2V : Valid signal at input, output mute by programming ADR 0x09[5]=1 (Enable override output MUX), MUX register setting is mute by default.
Here is my questions.
Q1) Is this the normal operation(behavior) for DS110DF410 ?
Q2) Why does the output have some voltage at mute ?
Q3) Why does the output voltage level differ at with or without input signal ?
Thanks and Best Regards,
