Available in two 16- pin small outline (SOIC) packages, it eliminates the need for a separate DSP data pump, modem controller, analog front end (AFE), isolation Si3015 transformer, relays, opto-isolators, 2- to 4-wire hybrid, and voice codec. QE2 FILT2 1 16 The Si2400 is ideal for embedded modem applications due to its small DCT 2 FILT 15 board space, low power consumption, and global compliance.
