Third-Generation Codec ac Interface Network: Complex Termination
The following reference circuit shows the complete SLIC schematic for interface to the Agere T8536 third-genera-
tion. All ac parameters are programmed by the T8536. Note this codec differentiates itself in that no external com-
ponents are required in the ac interface to provide a dc termination impedance or for stability. Also, this example
illustrates the device using the battery switch with multiple battery operation and programmable overhead, current
limit, and loop closure threshold. Please see the T8535/6 data sheet for information on coefficient programming.
