SI2457-D-FTR Application Field and Working Principle

The SI2457-D-FTR from Zarlink Semiconductor is a high-performance, low-power, industry-standard interface IC for connecting voice applications with the PSTN. It supports both voice-grade and high-bandwidth applications. It is well suited for applications such as DOCSIS, optical networking, digital PBXs, VoIP gateways, set-top boxes and digital telephony systems.

The SI2457-D-FTR is an interface IC that provides digital analog interfaces between Voice over Internet Protocol (VoIP) equipment and the digital PBX and/or PSTN networks. It is used to bridge digital voice signals between VoIP equipment and digital PBX or PSTN networks. The SI2457-D-FTR offers 8 digital outputs that can be connected directly to digital PBX and PSTN networks, or through a digital interface converter to analog PBX and analog PSTN networks.

The SI2457-D-FTR is designed to operate efficiently, even in quiet environments with low air flow; this makes it highly suitable for use in medical, military, telephony and other mission-critical applications. The IC also has an integrated auto-sensing system which simplifies the connection of either a single pair of wires or a two-pair/RJ-11-X crossover cable. This provides a reliable link between the IC and the external device.

The SI2457-D-FTR is designed to maximize the performance of digital equipment while lowering power consumption. It features a low-power receiver with a power rating of 1 mW and a low-power transmitter with a rating of 10 mW. The IC also incorporates a power management system that ensures the components are turned off when not in use, which lowers the overall power consumption.

The SI2457-D-FTR is designed to be flexible; it can accommodate a variety of line types, such as E1, T1, X.25, and E2. The IC also supports multiple and simultaneous protocols, making it suitable for applications requiring multiple features, such as encryption, data compression, and VoIP.

The IC is equipped with an analog output multiplexer, which allows it to connect to a wide range of digital devices, such as digital phones, PC cards and VoIP gateways. This allows the IC to be easily integrated into almost any digital system.

The SI2457-D-FTR is designed to provide a highly reliable, low-power connection between digital equipment and digital PBX and PSTN networks. It is an ideal choice for applications requiring reliable, high-performance, low-power connectivity.
