Mapping of the input voltage to the various data formats is
shown in Table 5.
Serial Peripheral Interface
A serial peripheral interface (SPI) bus is used to facilitate
configuration of the device and to optimize performance. The
SPI bus consists of chip select (CSB), serial clock (SCLK)
serial data input (SDI), and serial data input/output (SDIO).
The maximum SCLK rate is equal to the ADC sample rate
(fSAMPLE) divided by 16 for write operations and fSAMPLE
divided by 66 for reads. At fSAMPLE = 250MHz, maximum
SCLK is 15.63MHz for writing and 3.79MHz for read
operations. There is no minimum SCLK rate.
The following sections describe various registers that are
used to configure the SPI or adjust performance or functional
parameters. Many registers in the available address space
(0x00 to 0xFF) are not defined in this document. Additionally,
within a defined register there may be certain bits or bit
combinations that are reserved. Undefined registers and
undefined values within defined registers are reserved and
should not be selected. Setting any reserved register or value
may produce indeterminate results.
