SI2404-D-FT Description

Short technical summary and product information.

The Skyworks Solutions SI2404-D-FT is a system-side ISOmodem IC, part of a family of modems ranging from 2400 bps to 56,000 bps. It utilizes patented direct access arrangement (DAA) technology for a programmable telephone line interface with high integration, eliminating the need for external components like DSPs, controllers, codecs, transformers, and crystals.

This device supports multiple data modem formats including ITU-T, Bell, V.21, V.22, V.23, V.29, and MNP2-5, with automatic rate negotiation. It features a UART, SPI, or parallel interface and offers flexible clock options. The integrated DAA provides over 6000 V capacitive isolation, parallel phone detect, and overcurrent detection.

Available in a 24-TSSOP package, the SI2404-D-FT is suitable for embedded modem applications due to its flexibility, small footprint, and minimal external component count. It also supports AT command set, SMS/MMS, firmware upgrades, and DTMF detection/generation.

Key electrical specifications include an operating voltage range of 3V to 3.6V. The device is surface mountable and comes in a 24-TSSOP package.
