2.2.4. Serial Port Interface
The CS5531/32/33/34’s serial interface consists of
four control lines: CS, SDI, SDO, SCLK. Figure 7
details the command and data word timing.
CS, Chip Select, is the control line which enables
access to the serial port. If the CS pin is tied low,
the port can function as a three-wire interface.
SDI, Serial Data In, is the data signal used to trans-
fer data to the converters.
SDO, Serial Data Out, is the data signal used to
transfer output data from the converters. The SDO
output will be held at high impedance any time CS
is at logic 1.
SCLK, Serial Clock, is the serial bit-clock which
controls the shifting of data to or from the ADC’s
serial port. The CS pin must be held low (logic 0)
before SCLK transitions can be recognized by the
port logic. To accommodate optoisolators SCLK is
designed with a Schmitt-trigger input to allow an
optoisolator with slower rise and fall times to di-
rectly drive the pin. Additionally, SDO is capable
of sinking or sourcing up to 5 mA to directly drive
an optoisolator LED. SDO will have less than a 400
mV loss in the drive voltage when sinking or sourc-
ing 5 mA.
