Reset/Self-Calibration Modes
The A/D converter will usually reset itself upon
power-up. Since this function is not guaranteed,
the converter must be reset upon power-up in
system operation. The converter can be reset on
the CDB5012, CDB5012A, CDB5014, CDB5016
board by momentarily depressing push-button
SW-2 thus initiating a full calibration cycle;
1,443,840 master clock cycles later the converter
is ready for normal operation.
The converters also feature two other calibration
modes: burst and interleave. The use of Burst
calibration is not recommended. Interleave can be
initiated by setting switch position 3 to the on
position. In the interleave mode (INTRLV low),
the converter appends one small portion of a cali-
bration cycle (20 master clock cycles) to each
conversion cycle. Thus, a full calibration cycle
completes every 72,192 conversion cycles. The
Interleave calibration mode should not be used
intermittently.
A more detailed discussion of the converters’
calibration modes and capabilities can be found
in their data sheets.
Parallel Output Data/Microprocessor Interface
The converter’s outputs D0-D15, its CS, RD, and
A0 inputs, and its EOC output are available at
the 40 pin header. The CS and RD inputs are
pulled low through 10 k
resistors placing
the converter in a microprocessor-independent
mode. Control input A0 is pulled up, insuring the
converter’s output word, rather than the status
register, appears at the header.
The converter’s 3-state output buffers and micro-
processor interface can be exercised by driving
the CS and/or RD inputs at the header. Similarly,
the converter’s 8-bit status register can be ob-
tained on D0-D7 by driving A0 low.
The converter’s EOC and data outputs are not
b u ffe re d on the CDB 501 2, CDB 501 2A,
CDB5014, CDB5016. Therefore, careful attention
should be paid to the load presented by any ca-
bling, especially if the 3-state output buffers are
to be exercised at speed. Twisted ribbon cable is
typically specified at 10pF/ft, so several feet can
generally be accommodated.
Serial Output Data
Serial output data is available at the two BNC
connections SCLK and SDATA. Data appears
MSB first, LSB last, and is valid on the rising
edge of SCLK.
Master Clock
The A/D converter operates from a master clock
which can either be internally-generated or exter-
nally-supplied. For operation with an external
clock, the BNC connector labeled CLKIN
should be driven with a TTL clock signal. The
CDB5012, CDB5012A, CDB5014, CDB5016 is
shipped from the factory with the CLKIN input
