Advance Information Dual 16-Bit Linear Codec-Filter
The MC143416 Dual 16–Bit Linear Codec–Filter is a single–chip implementation of the data conversion interface required to design high–speed modems meeting a wide range of standards such as ITU–T V.34 and PCM modem. It includes two high performance Analog–to–Digital (A/D) and Digital–to–Analog (D/A) data converters. The device performs all filtering operations related to the conditioning and sample rate conversion of signals to and from the data interface. Output from both codecs (COder/DECoder) is in 16–bit 2s complement format. The MC143416 includes the necessary logic needed to generate all clocks (oversampling, intermediate frequency, and baud rate) required to perform the data processing operations involved in the oversampling conversion of voice and data signals. Sample rates are fully programmable in the range of 8 kilosamples/second (ks/s) to 16 ks/s, including 8000, 9600, 11025, 12000, and 16000 samples/second. The bandwidth of the MC143416 is 0.425 * Sample Frequency (FS). The MC143416 includes two Synchronous Serial Interfaces (SSIs) through which an external Digital Signal Processor (DSP) can configure and monitor the operation of the device. Digital sample data is transferred to and from the codecs through the serial ports. In addition, information can be written and read to the control and status registers of the device via the ...
