... Dual 16-Bit Stereo Audio Sigma-Delta ADC CMOS The MC145073 is a dual–channel, 16–bit A/D converter intended for use in digital audio systems such as multimedia, DCC, DAT, and professional audio applications. It uses a sigma–delta architecture consisting of a second–order analog modulator and two stages of digital filtering for each channel. The analog modulator samples the input signal at 128 times the output data rate, performs a single– ...

... Serial Interface Data Output (Pin 13) The A/D conversion results for the left and right channels are output on this pin. Data is shifted out of the MC145073 MSB first, with the left channel data preceding the right chan- nel data. The serial output data is clocked out on the rising edge of SCLK ...

... Analog input sig- nals that exceed the differential analog input voltage range of 3.8 V p–p are clipped in order to prevent overflow of the digi- tal filters. The MC145073 operates from a single 5 V power supply. For portable or other low power applications, a pow- er–down mode is available. ...

... MC145073 as a master tied to a second MC145073 operating as a slave due to the reclock- ing of the SYNC and SCLK inputs in the slave mode (see Operation with the MC145073 as a Slave (I SLAV = 1) sec- tion). NOTE When multiplexing two MC145073 devices, all four analog channels are sampled at exactly the same phase ...

... When I SLAV = 1 the SYNC and SCLK signals are defined as inputs, and the MC145073 is configured as a slave de- vice. However, the slave mode of the MC145073 is not a true slave mode since the SYNC and SCLK inputs are reclocked by the internal sample clock, CLKI. These internal reclocked versions of SYNC and SCLK are shown in Figure 11, in addi- tion to the external SYNC and SCLK signals ...
