Ultra-Low-Power, Octal, 12-Bit, 50Msps,
1.8V ADC with Serial LVDS Outputs
MAX19527

The first byte transmitted on SDIO is always provided by
the master. The ADC (slave device) clocks in the data
from SDIO on each rising edge of SCLK. The first bit
received selects whether the communication cycle is a
read or write. Logic 1 selects a read cycle, while logic 0
selects a write cycle. The next 7 bits (MSB first) are the
register address for the read or write cycle. The address
can indicate any of the 10 user-programmable control
registers (00h to 09h), or the special-function register
(10h, write only). Attempting to read/write with any other
address has no effect (Table 1).
The second byte on SDIO is sent to the ADC in the case
of a write, or received from the ADC in the case of a read.
For a write command, the device continues to clock in the
data on SDIO on each rising edge of SCLK. In the case
of a read command, the device writes data to SDIO on
each falling edge of SCLK. The data byte is transmitted
and received MSB first in both cases. The detailed SPI
timing requirements are shown in Figure 9.
User-Programmable Control Registers
The ADC has 10 user-programmable control regis-
ters, and one special-function register (Table 1). Each
register is set to its power-on-reset (POR) default value
when the device powers up or after a reset condition
clears.
PLL Sampling Rate and
Power Management Register (00h)
The PLL Sampling Rate and Power-Management register
(00h, Table 2) has two distinct functions. The first is to
adjust the internal PLL to facilitate a wide range of input
sampling frequencies. The second is to set the type of
power-down mode used by each power state (set by
SHDN).
