FX1000/FX1041 FXO for Voice over IP Applications Video Server, and VTR Applications Product Brief Features n FX1000 plus FX1041 implements complete Foreign Exchange Office (FXO) functionality n 24-pin MLCC (4 x 4 mm) FX1000 package n SoC interface (compatible with other Foreign Exchange Subscriber (FXS) and FXO devices): – Serial Peripheral Interface (SPI) for control – Time-division multiplexed (TDM) interface for data (up to 8.192 MHz) n Single 3.3-V supply with 5-V-tolerant I/O n No external crystal required (uses TDM clock) n System-powered solution n Greater than 4KV Isolation n Single programmable solution for worldwide support n Overcurrent Protection n Line snooping n Supports multiple interrupt events n FXO functionality: – Highest voice quality with low noise (16-bit linear codec w/ >80 dB dynamic range) – Ring detect – Support for Type I and Type II caller ID – General-purpose I/O (GPIO) interface to support ground start applications – FXO call-disconnect detection on loop start lines – Hardware support for pulse dialing The FX1000, when used with the FX1041 line-side codec, provides all of the functionality required to implement an FXO for Voice over IP (VoIP) applications. The FX1000 provides the interface to the VoIP SoC through its TDM interface (for data) and SPI bus (for control), and an interface to the FX1041 Line-side codec through a high-voltage isolation barrier.
