摘要： An improved modem architecture and associated method are disclosed that integrate modem and line-isolation circuitry so as to achieve modem functionality and system-side isolation functionality on a single integrated circuit. The combined modem and line isolation system has both on-hook and off-hook intrusion detection for use with parallel connected phone line connection devices. During on-hook intrusion detection, when the combined modem and line isolation system is on-hook the system can detect if other parallel connected phone line connection devices are already off-hook. During off-hook intrusion detection, when the combined modem and line isolation system is off-hook the system can detect if other parallel connected phone line connection devices are attempting to go off-hook.

During off-hook intrusion detection, when the combined modem and line isolation system is off-hook the system can detect if other parallel connected phone line connection devices are attempting to go off-hook. On-hook intrusion detection may be accomplished by monitoring the phone line voltage through a pin utilized for setting DC termination characteristics.

摘要： A digital direct access arrangement (DAA) circuitry may be used to terminate the telephone connections at the user's end that provides a communication path for signals to and from the phone lines. Briefly described, the DAA provides a programmable means for the DC termination for a variety of international phone standards. The invention may also be utilized with means for transmitting and receiving a signal across a capacitive isolation barrier. More particularly, a DC holding circuit is provided in which a programmable DC current limiting mode is available. In the current limiting mode, power may be dissipated in devices external to a DAA integrated circuit. Moreover, much of the power may be dissipated in external passive devices, such as resistors.

摘要： ESD (electrostatic discharge) protection for radio frequency (RF) couplers included in the same semiconductor package as other integrated circuits, such as integrated circuits having power amplifier (PA) circuitry, is disclosed along with related systems and methods. The disclosed embodiments provide ESD protection for RF couplers within semiconductor packages by including coupler ESD circuitry within an integrated circuit within the semiconductor package and coupling the connection ports of the RF coupler to this coupler ESD circuitry. Further, this coupler ESD circuitry can be implemented using two sets of serially connected diodes so that the signal connected to the coupler ESD circuitry can swing around ground without being clipped by the ESD circuitry. Still further, the ESD diodes can be formed in deep N well structures to improve isolation and to reduce parasitic capacitance associated with the ESD diodes.
