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, programmable current limit, and pro-
grammable loop closure threshold. Please see the T8535/6 data sheet for information on coefficient programming.
