Figure 6. 24-Bit External Clock Mode Conversion Timing (SPI, QSPI and Microwire Compatible)
Figure 7. Detailed Serial-Interface Timing
Pulling
CS
high prevents data from being clocked into
the MAX192 and three-states DOUT, but it does not
adversely affect an internal clock-mode conversion
already in progress. When internal clock mode is
selected, SSTRB does not go into a high-impedance
state when
CS
goes high.
Figure 10 shows the SSTRB timing in internal clock
mode. In internal clock mode, data can be shifted in
and out of the MAX192 at clock rates exceeding
4.0MHz, provided that the minimum acquisition time,
t
AZ
, is kept above 1.5μs.
Data Framing
The falling edge of
CS
does
not
start a conversion on
the MAX192. The first logic high clocked into DIN is inter-
preted as a start bit and defines the first bit of the control
byte. A conversion starts on the falling edge of SCLK,
after the eighth bit of the control byte (the PD0 bit) is
clocked into DIN. The start bit is defined as:
The first high bit clocked into DIN with
CS
low any-
time the converter is idle, e.g. after V
DD
is applied.
OR
The first high bit clocked into DIN after bit 3 of a
conversion in progress is clocked onto the DOUT pin.
If a falling edge on
CS
forces a start bit before bit 3
(B3) becomes available, then the current conversion
will be terminated and a new one started. Thus, the
fastest the MAX192 can run is 15 clocks per conver-
sion. Figure 11a shows the serial-interface timing nec-
essary to perform a conversion every 15 SCLK cycles
in external clock mode. If
CS
is low and SCLK is contin-
uous, guarantee a start bit by first clocking in 16 zeros.
