DESCRIPTION

· The Si2435 and Si2417 are two-chip fax modems with speeds from 33,600 bps to 14,400 bps.
· They feature a globally-programmable telephone line interface using Silicon Laboratories' third-generation DAA.
· These chipsets eliminate the need for additional components like DSP, modem controller, and isolation transformer.
· They support fax formats up to 33,600 bps over PSTN, ideal for fax modem applications due to global compliance and minimal external components.

FEATURES

· Supports fax modem formats V.29, V.27ter, V.17, V.21 channel 2, and V.34 half duplex.
· Features automatic rate negotiation and supports type I and II caller ID.
· No external ROM or RAM required; includes distinctive ring detection.
· Offers UART or parallel interface; available in lead-free/RoHS-compliant packages.
· Integrated DAA with over 6000 V capacitive isolation and globally-compliant line interface.
· Includes overcurrent detection, firmware upgradeability, DTMF detection/generation, and data/fax discriminator.

APPLICATIONS

· Suitable for fax machines, fax telephones, multifunctional printers, and fax servers.
· Ideal for applications requiring serial or parallel interface with a microcontroller or DSP.
