General Description
The CS42428 CODEC provides two analog-to-digital and eight
digital-to-analog Delta-Sigma converters, as well as an inte-
grated PLL, in a 64-pin LQFP package.
The CS42428 integrated PLL provides a low-jitter system
clock. The internal stereo ADC is capable of independent chan-
nel gain control for single-ended or differential analog inputs.
All eight channels of DAC provide digital volume control and
differential analog outputs. The general purpose outputs may
be driven high or low, or mapped to a variety of DAC mute con-
trols or ADC overflow indicators.
The CS42428 is ideal for audio systems requiring wide dynam-
ic range, negligible distortion and low noise, such as A/V
receivers, DVD receivers, digital speaker and automotive audio
systems.

... All functions are configured through a serial control port operable in SPI mode mode. Figure 1 shows the recommended connections for the CS42428. The CS42428 operates in one of three oversampling modes based on the input sample rate. Mode selection is determined by the FM bits in register “Functional Mode (address 03h)” on page 33. Single-Speed mode (SSM) supports input sample rates kHz and uses a 128x oversampling ratio ...

... This feature makes it possible to perform a system DC offset calibration by: 1) Running the CS42428 with the high pass filter enabled until the filter settles. See the Digital Filter Characteristics for filter settling time. 2) Disabling the high pass filter and freezing the stored DC offset. ...

Page 12

... The CS42428 is a linear phase design and does not include phase or amplitude compensation for an exter- nal filter. Therefore, the DAC system phase and amplitude response will be dependent on the external an- alog circuitry. Figure 4 shows the full-scale analog output levels.

... All other transitions of SDA occur while the clock is low. The first byte sent to the CS42428 after a Start condition consists bit chip address field and a R/W bit (high for a read, low for a write). The upper 5 bits of the 7-bit address field are fixed at 10011. To communicate with a CS42428, the chip address field, which is the first byte sent to the CS42428, should match 10011 followed by the settings of the AD1 and AD0 ...

... Interrupts The CS42428 has a comprehensive interrupt capability. The INT output pin is intended to drive the inter- rupt input pin on the host microcontroller. The INT pin may be set to be active low, active high or active low with no active pull-up transistor. This last mode is used for active low, wired-OR hook-ups, with mul- tiple peripherals connected to the microcontroller interrupt input pin. Many conditions can cause an interrupt, as listed in the interrupt status register descriptions. See “ ...
