What is name of the IC manufacturer with this logo?

Probably it is Chinese manufacturer. I wasn't able to find it here or here.

I need to find specification or datasheet of its audio bluetooth reciever circuits 1748NRZ-11F and 17280-11C.

These chips are used in bluetooth car media players like this one.
