DSP Interface
The DSP mode of the MAX1068 only operates in exter-
nal clock mode. Figure 23 shows a typical DSP interface
connection to the MAX1068. Use the same oscillator as
the DSP to provide the clock signal for the MAX1068.
The DSP provides the falling edge at
CS
to wake the
MAX1068. The MAX1068 detects the state of DSPR on
the falling edge of
CS
(Figure 17). Logic low at DSPR
places the MAX1068 in DSP mode. After the MAX1068
enters DSP mode,
CS
can be left low. A frame sync
pulse from the DSP to DSPR initiates a conversion. The
MAX1068 sends a frame sync pulse from DSPX to the
DSP signaling that the MSB is available at DOUT. Send
another frame sync pulse from the DSP to DSPR to
begin the next conversion. The MAX1068 does not
operate in scan mode when using DSP mode.
