SV92A3
The SV92A3 device provides a dual-mode AC’97 and HD Audio interface with automatic mode detection. The SV92A3 is available in a 16-pin TSSOP package. A new version (SV92A35) is also available that supports 1.5v as well as 3.3v signalling. The SV92A3 includes logic to provide robust ring detection and qualification eliminating unintended wake-on-ring events due to activity on the phone line other than ringing. The SV92A3 also handles pulse dial timing control in hardware to eliminate system timing dependencies common with earlier soft modem products.
