Hi Everybody,
Currently developing a PCI host card to host a wireless modem The modem has a differential speaker output and a differential mic input. My problem is that i want to connect these audio ports to their corresponding ports on a PCI sound card in the same system, which has single ended input/outputs. If i do this directly then i will end up grounding one side of each differential pair.
I have thought of using a audio transformer to convert from differential mode to single mode and vice versa. However i am not sure of the circuitry/ components etc
The output speaker differential impedance is 1 Ohm and the mic input differential impedance is 20K.
I would appreciate any help i can get with this.
