Serial Data Input ( Input ) - Two’s complement MSB-first serial data is input on this pin. The
required relationship between the left/right clock, serial clock and serial data is defined by the
DSP Port Mode (05h) register. The options are detailed in Figures 8 - 11.
Serial Control Port Clock ( Input ) - Clocks the serial control bits into and out of the CS4221.
In I
Serial Control Port Data ( Input/Output )- SDA is a data I/O line in I
external pull-up resistor according to the I
serial control port in SPI mode.
Address Bit/Control Chip Select ( Input ) - In I
mode, CS is used to enable the control port interface on the CS4221. The CS4221 control port
interface is defined by the SPI/I2C pin.
Logic Power ( Input ) - Positive power supply for the digital interface section. Typically 3.0 to
5.0 VDC.
Differential Right Channel Analog Input ( Input ) - The full scale analog input level (differen-
tial) is specified in the Analog Characteristics specification table and may be AC coupled or DC
coupled into the device, see Figure 12 for optional line input buffer.
Control Port Format ( Input ) - When this pin is high, I
selected.
Differential Left Channel Analog Input ( Input ) - The full scale analog input level (differential)
is specified in the Analog Characteristics specification table and may be AC coupled or DC
coupled into the device, see Figure 12 for optional line input buffer.
Analog Power ( Input ) - Positive power supply for the analog section. Typically 5.0 VDC.
Analog Ground ( Input ) - Analog ground reference.
Differential Right Channel Analog Outputs ( Output ) - The full scale analog output level (dif-
ferential) is specified in the Analog Characteristics specification table.
Differential Left Channel Analog Outputs ( Output ) - The full scale analog output level (dif-
ferential) is specified in the Analog Characteristics specification table.
Reset ( Input ) - When low, the device enters a low power mode and all internal registers are
reset, including the control port. When high, the control port becomes operational and normal
operation will occur.
2
C mode, SCL requires an external pull-up resistor according to the I
2
C specification. CDIN in the input data line for the
2
C mode, AD0 is a chip address bit. In SPI
2
C mode is selected, when low, SPI is
CS4220 CS4221
2
C mode and requires an
2
C specification.
