The ST7544 is a single chip Analog Front-End (AFE) designed to implement high speed voicegrade Modems up to 28800 bps with echo cancelling capability.
Associated with one or several Digital Signal Processors (DSP), such as the ST189XX family, it provides a powerfulsolution for the implementation of multi-mode Modems meeting CCITT (V.21, V.22, V.22 bis, V.23, V.26, V.27, V.29, V.32,V.32 bis and V.33) and BELL (103, 202, 212A...) recommendations. It is fully compatible with the ST7543 in 7543 mode and is also well suited emerging applications involving bit rates up to 28800 bps (in the VFast synchronization mode).
The transmit section includes a 16-bit over-sampling D/A converter with a programmable interpolating filter. The receive section includes a 16-bit oversampling A/D converter with two programmable filters (one for decimation and the other for reconstruction).Oversampling ratio is selectable to either 128 or 160.Two additional 8-bit D/A converters allow eyediagram monitoring on a scope for modem performance adjustment.
Two independantclock generator systems are provided, one synchronized on the Tx rate and the other on the Rx rate.
In External Clock Mode, external oversampling clocks can be provided to the chip.
Two independant synchronous serial interfaces (SSI) allow several versatile ways of communicating with standard DSPs.
To savepower, e.g. in lap-topmodem applications,the lowpower reset mode can be used to reduce the power consumption to less than 5mW.
