Detailed Description
Theory of Operation
Analog Input
The HI5714 design utilizes a folding and interpolating
architecture. This architecture reduces the number of
comparators, reference taps, and latches, thereby reducing
power requirements, die size and cost.
The analog input will accept a voltage within the reference
voltage levels, VRB and VRT, minus some offset. The offset
is specified in the Electrical Specifications table.
A folding A/D converter operates basically like a 2 step
subranging converter by using 2 lower resolution converters
to do a course and subranged fine conversion. A more
complete description is given in the application note “Using
the HI5714 Evaluation Module” (AN9517).
The analog input is relatively high impedance (10k) but
should be driven from a low impedance source. The input
capacitance is low (14pF) and there is little kickback from the
input, so a series resistance is not necessary but it may help
to prevent the driving amplifier from oscillating.
Reference Input, VRT and VRB
The input bandwidth is typically 18MHz. Exceeding 18MHz
will result in sparkle at the digital outputs. The bandwidth
remains constant at clock rates up to 75MHz.
The HI5714 requires an external reference to be connected
to pins 4 and 9, VRB and VRT.
It is recommended that adequate high frequency decoupling
be provided at the reference input pin in order to minimize
overall converter noise. A 0.1F and a 1nF capacitor as
close as possible to the reference pins work well.
VRT must be kept within the range of 3.5V to 3.9V and VRB
within 1.2V to 1.6V. If the reference voltages go outside their
respective ranges, the input folding amplifiers may saturate
giving erroneous digital data. The range for (VRT - VRB) is
1.9V to 2.7V, which defines the analog input range.
Digital Control and Clock Requirements
The HI5714 provides a standard high-speed interface to
external TTL logic families.
The outputs can be three-stated by setting the OE input (pin
22) high.
The clock input operates at standard TTL levels as well as a
low level sine wave around the threshold level. The HI5714
can operate with clock frequencies from DC to 75MHz. The
clock duty cycle should be 50% 10% to ensure rated
performance. Duty cycle variation, within the specified
range, has little effect on performance. Due to the clock
speed it is important to remember that clock jitter will affect
the quality of the digital output data.
The clock can be stopped at any time and restarted at a later
time. Once restarted the digital data will be valid at the
second rising edge of the clock plus the data delay time.
Digital Outputs and O/UF Output
The digital outputs are standard TTL type outputs. The
HI5714 can drive 1 to 3 TTL inputs depending on the input
current requirements.
Should the analog input exceed the top or bottom reference
the over/underflow output (pin 11) will go high. Should the
analog input exceed the top reference voltage, VRT, the
digital outputs will remain at all 1s until the analog input goes
below VRT. Also, should the analog input go below the
9
Supply and Ground Considerations
In order to keep digital noise out of the analog signal path,
the HI5714 has separate analog and digital supply and
ground pins. The part should be mounted on a board that
provides separate low impedance connections for the analog
and digital supplies and grounds.
The analog and digital grounds should be tied together at
one point near the HI5714. The grounds can be connected
directly, through an inductor (ferrite bead), or a low valued
resistor. DGND and AGND can be tied together. To help
minimize noise, tie pin 5 (NC) to AGND and pins 3 (NC) and
10 (NC) to DGND.
For best performance, the supplies to the HI5714 should be
driven by clean, linear regulated supplies. The board should
also have good high frequency leaded decoupling capacitors
mounted as close as possible to the converter. Capacitor
leads must be kept as short as possible (less than 1/2 inch
total length). A 0.1F and a 1nF capacitor as close as
possible to the pin works well. Chip capacitors will provide
better high frequency decoupling but leaded capacitors
appear to be adequate.
If the part is to be powered by a single supply, then the
analog supply pins should be isolated by ferrite beads from
the digital supply pins. This should help minimize noise on
the analog power pins.
Refer to Application Note AN9214, “Using Intersil High
Speed A/D Converters”, for additional considerations when
using high speed converters.
Increased Accuracy
Further calibration of the ADC can be done to increase
absolute level accuracy. First, a precision voltage equal to
the ideal VIN-FS + 0.5 LSB is applied at VIN . Adjust VRB
until the 0 to 1 transition occurs on the digital output. Next, a
voltage equal to the ideal VIN+FS - 1.5 LSB is applied at VIN .
VRT is then adjusted until the 254 to 255 transition occurs on
the digital output.
HI5714
Due to the high clock rate, FCT (TTL/CMOS) or FAST (TTL)
glue logic should be used. FCT logic will tend to have large
overshoots if not loaded. Long traces (>2 or 3 inches) should
be terminated to maintain signal integrity.

Timing Definitions
Bottom Offset Voltage (VOB)
Aperture Delay: Aperture delay is the time delay between
the external sample command (the rising edge of the clock)
and the time at which the signal is actually sampled. This
delay is due to internal clock path propagation delays.
The first code transition should occur at a level 0.5 LSB
above the negative full-scale. Bottom offset voltage is
defined as the deviation of the actual code transition from
this point.
Aperture Jitter: This is the RMS variation in the aperture
delay due to variation of internal clock path delays.
Top Offset Voltage (VOT)
Data Latency
After the analog sample is taken, the data on the bus is
output at the next rising edge of the clock. This is due to the
output latch of the converter. This delay is specified as the
data latency. After the data latency time, the data
representing each succeeding sample is output at the
following clock pulse. The digital data lags the analog input
by 1 cycle.
Static Performance Definitions
Offset Error and Full-Scale Error use a measured value of
the external voltage reference to determine the ideal plus
and minus full-scale values. The results are all displayed in
LSBs.
11
The last code transition should occur for a analog input that
is 1.5 LSBs below positive full-scale. Top Offset Voltage is
defined as the deviation of the actual code transition from
this point.
Differential Linearity Error (DNL)
DNL is the worst case deviation of a code width from the
ideal value of 1 LSB. The converter is guaranteed to have no
missing codes.
Integral Linearity Error (INL)
INL is the worst case deviation of a code center from a best
fit straight line calculated from the measured data.
HI5714
Dynamic Performance Definitions
Signal-to-Noise + Distortion Ratio (SINAD)
Fast Fourier Transform (FFT) techniques are used to
evaluate the dynamic performance of the HI5714. A low
distortion sine wave is applied to the input, it is sampled, and
the output is stored in RAM. The data is then transformed
into the frequency domain with a 2048 point FFT and
analyzed to evaluate the dynamic performance of the A/D.
The sine wave input to the part is 0.5dB down from full scale
for these tests. The distortion numbers are quoted in dBc
(decibels with respect to carrier) and DO NOT include any
correction factors for normalizing to full scale.
SINAD is the measured RMS signal to RMS sum of all other
spectral components below the Nyquist frequency excluding
DC.
Signal-to-Noise Ratio (SNR)
SNR is the measured RMS signal to RMS noise at a
specified input and sampling frequency. The noise is the
RMS sum of all of the spectral components except the
fundamental and the first five harmonics.
12
Effective Number Of Bits (ENOB)
The effective number of bits (ENOB) is derived from the
SINAD data. ENOB is calculated from:
ENOB = (SINAD - 1.76) / 6.02
2nd and 3rd Harmonic Distortion
This is the ratio of the RMS value of the 2nd and 3rd
harmonic component respectively to the RMS value of the
measured input signal.
Full Power Input Bandwidth
Full power bandwidth is the frequency at which the
amplitude of the digitally reconstructed output has
decreased 3dB below the amplitude of the input sine wave.
The input sine wave has a peak-to-peak amplitude equal to
the difference between the top reference voltage input and
the bottom reference voltage input. The bandwidth given is
measured at the specified sampling frequency.
