CPC7582BB

The CPC7582BB is a single-phase PC board module designed for interfacing equipment to the public switched telephone network (PSTN). Specifically, the CPC7582BB interfaces four analog lines totaling up to a maximum of 1272 ohms to the PSTN. It is ideal for residential customers who want to connect their equipment to the PSTN for interactive voice, data, and imagery transmission.

The CPC7582BB works on the principle of balanced compensated four-wire and two-wire interfaces. In the balanced compensated four-wire interface mode, the CPC7582BB operates as an interface between the subscriber\'s equipment and the PSTN. It transmits voice signals and supplies power to the line when necessary. The other two-wire mode facilitates the transmission of data only.

The CPC7582BB has several characteristics that make it ideal for residential applications. It offers an adaptive, on-demand equalizer. This equalizer adjusts itself automatically according to the characteristics of the line, improving signal quality and reducing line noise. In addition, the CPC7582BB provides programmable overshoot and undershoot protection, optional power control on lines, protective LIP (Loubtourns Initiation Pulse) current limiters, dynamic line amplifier emulation, and adjustable common-mode voltage.

In addition, the CPC7582BB is certified to comply with various regulatory standards, including Digital Subscriber Interface & Advanced Digital Access Subrates (DSI/ADAS), Digital Subscriber Interface (DSI), European Telecommunications Standards Institute (ETSI), Bell Communications Research (Bellcore), Bell Telephone Laboratories (BTL), and North American Telcordia. Furthermore, the CPC7582BB is verified to meet requirements for UL 1950 and Electromagnetic Compatibility (EMC).

The CPC7582BB has a wide range of applications, including residential telephone systems, automated answering devices, facsimile machines, PC modems, alarm systems and other credit control services. The CPC7582BB is particularly well-suited for point-to-point, point-to-multipoint and broadcast voice and data applications.

The CPC7582BB is a reliable and energy-efficient module. It has a low power consumption and its power requirements can be scaled down based on application. It can also be powered down completely when not in use in order to save energy. The CPC7582BB also has a wide voltage input range of +/- 5.5V, which makes it well-suited for use in customer premises equipment (CPE) applications.

In summary, the CPC7582BB is an ideal single-phase PC board module for interfacing customer equipment to the PSTN. It is especially well-suited for residential applications because of its voltage input range, adaptive equalizer and compliance with multiple regulatory standards.
