AVCLK, DVDD3.3, and DVDD1.8), which minimize noise
coupling from one supply to the other. AVDD1.8 and
DVDD1.8 operate from a typical 1.8V supply, and all
other supply inputs operate from a typical 3.3V supply.
Serial Interface
The SPI-compatible serial interface programs the
MAX5898 registers. The serial interface consists of CS,
DIN, SCLK, and DOUT. Data is shifted into DIN on the
rising edge of SCLK when CS is low. When CS is high,
data presented at DIN is ignored and DOUT is in high-
impedance mode. Note:
CS must transition high
after each read/write operation. DOUT is the serial
data output for reading registers to facilitate easy
debugging during development. DIN and DOUT can
be connected together to form a 3-wire serial interface
bus or remain separate and form a 4-wire SPI bus.
The serial interface supports two-byte transfer in a
communication cycle. The first byte is a control byte
written to the MAX5898 only. The second byte is a data
byte and can be written to or read from the MAX5898.
When writing to the MAX5898, data is shifted into DIN;
data is shifted out of DOUT in a read operation. Bits 0 to
3 of the control byte are the address bits. These bits set
the address of the register to be written to or read from.
Bits 4 to 6 of the control byte must always be set to 0.
Bit 7 is a read/write bit: 0 for write operation and 1 for
read operation. The most significant bit (MSB) is shifted
in first in default mode. If the serial port is set to LSB-first
mode, both the control byte and data byte are shifted LSB
first. Figures 1 and 2 show the SPI serial-interface opera-
tion in the default write and read mode, respectively.
Figure 3 is a timing diagram for the SPI serial interface.
