SI2400-FS Description

Short technical summary and product information.

The Si2400 ISOmodem from Skyworks Solutions is a comprehensive modem chipset featuring an integrated Direct Access Arrangement (DAA) for global telephone line compatibility. This device eliminates the need for external DSP data pumps, modem controllers, and analog front ends, making it ideal for embedded applications requiring minimal board space.

Key features include support for multiple data modem formats such as V.22bis (2400 bps), V.22, V.23, Bell 212A (1200 bps), and V.21, Bell 103 (300 bps), along with SIA and other security protocols. It also offers Caller ID detection, DTMF tone generation and detection, and an integrated voice codec. The Si2400 operates on a 3.3V or 5.0V power supply and includes a UART with flow control.

Designed for global compliance, the Si2400 provides a programmable line interface with capacitive isolation, parallel phone detection, and overcurrent detection. It supports AT command sets and offers PCM data pass-through mode. The device is available in a 16-pin SOIC package suitable for surface mounting.

Applications for the Si2400 include set-top boxes, power meters, security systems, ATM terminals, medical monitoring, and point-of-sale systems where embedded modem functionality is required.
