remains valid until tDHOLD after the following SCLK rising
edge. When using CPOL = 0 and CPHA = 0 or CPOL = 1
and CPHA = 1, the data is clocked into the P on the
following rising edge. When using CPOL = 0 and CPHA
= 1 or CPOL = 1 and CPHA = 0, the data is clocked
into the P on the next falling edge. See Figure 11 for
connections and Figures 12 and 13 for timing. See the
Timing Characteristics section to determine the best
mode to use.
QSPI
Unlike SPI, which requires two 1-byte reads to acquire
the 10 bits of data from the ADC, QSPI allows the mini-
mum number of clock cycles necessary to clock in the
data. The MAX1076/MAX1078 require 16 clock cycles
from the P to clock out the 10 bits of data. Figure 14
shows a transfer using CPOL = 1 and CPHA = 1. The
conversion result contains three zeros, followed by the
10 data bits, 2 sub-bits, and a trailing zero with the data
in MSB-first format.
DSP Interface to the TMS320C54_
The MAX1076/MAX1078 can be directly connected
to the TMS320C54_ family of DSPs from Texas
Instruments, Inc. Set the DSP to generate its own
clocks or use external clock signals. Use either the
standard or buffered serial port. Figure 15 shows the
simplest interface between the MAX1076/MAX1078 and
the TMS320C54_, where the transmit serial clock
(CLKX) drives the receive serial clock (CLKR) and
