12-Bit, 80 MSPS, High Speed Video D/A
Converter
The HI5735 is a 12-bit, 80 MSPS, D/A converter which is
implemented in the Intersil BiCMOS 10V (HBC-10) process.
Operating from +5V and -5.2V, the converter provides
-20.48mA of full scale output current and includes an input
data register and bandgap voltage reference. Low glitch
energy and excellent frequency domain performance are
achieved using a segmented architecture. The digital inputs
are TTL/CMOS compatible and translated internally to ECL.
All internal logic is implemented in ECL to achieve high
switching speed with low noise. The addition of laser
trimming assures 12-bit linearity is maintained along the
entire transfer curve.

Detailed Description
Clocks and Termination
The HI5735 is a 12-bit, current out D/A converter. The DAC
can convert at 80 MSPS and runs on +5V and -5.2V supplies.
The architecture is an R/2R and segmented switching current
cell arrangement to reduce glitch. Laser trimming is employed
to tune linearity to true 12-bit levels. The HI5735 achieves its
low power and high speed performance from an advanced
BiCMOS process. The HI5735 consumes 650mW (typical)
and has an improved hold time of only 0.25ns (typical).
The internal 12-bit register is updated on the rising edge of
the clock. Since the HI5735 clock rate can run to 80 MSPS,
to minimize reflections and clock noise into the part, proper
termination should be used. In PCB layout clock runs should
be kept short and have a minimum of loads. To guarantee
consistent results from board to board, controlled impedance
PCBs should be used with a characteristic line impedance
ZO of 50Ω.
Digital Inputs
To terminate the clock line, a shunt terminator to ground is
the most effective type at a 80 MSPS clock rate. A typical
value for termination can be determined by the equation:
The HI5735 is a TTL/CMOS compatible D/A. Data is latched
by a Master register. Once latched, data inputs D0 (LSB)
thru D11 (MSB) are internally translated from TTL to ECL.
The internal latch and switching current source controls are
implemented in ECL technology to maintain high switching
speeds and low noise characteristics.
Decoder/Driver
The architecture employs a split R/2R ladder and
Segmented Current source arrangement. Bits D0 (LSB) thru
D7 directly drive a typical R/2R network to create the binary
weighted current sources. Bits D8 thru D11 (MSB) pass thru
a “thermometer” decoder that converts the incoming data
into 15 individual segmented current source enables. This
split architecture helps to improve glitch, thus resulting in a
more constant glitch characteristic across the entire output
transfer function.

RT = ZO ,
for the termination resistor. For a controlled impedance
board with a ZO of 50Ω, the RT = 50Ω. Shunt termination is
best used at the receiving end of the transmission line or as
close to the HI5735 CLK pin as possible.

Rise and Fall times and propagation delay of the line will be
affected by the Shunt Terminator. The terminator should be
connected to DGND.
Noise Reduction
To reduce power supply noise, separate analog and digital
power supplies should be used with 0.1µF and 0.01µF
ceramic capacitors placed as close to the body of the
HI5735 as possible on the analog (AVEE) and digital (DVEE)
supplies. The analog and digital ground returns should be
connected together back at the device to ensure proper
operation on power up. The VCC power pin should also be
decoupled with a 0.1µF capacitor.
Reference
The internal reference of the HI5735 is a -1.23V (typical)
bandgap voltage reference with 50µV/oC of temperature drift
(typical). The internal reference is connected to the Control
Amplifier which in turn drives the segmented current cells.
Reference Out (REF OUT) is internally connected to the
Control Amplifier. The Control Amplifier Output (CTRL OUT)
should be used to drive the Control Amplifier Input (CTRL
IN) and a 0.1µF capacitor to analog VEE . This improves
settling time by providing an AC ground at the current source
base node. The Full Scale Output Current is controlled by
the REF OUT pin and the set resistor (RSET). The ratio is:
IOUT (Full Scale) = (VREF OUT /RSET) x 16.
The internal reference (REF OUT) can be overdriven with a
more precise external reference to provide better
performance over temperature. Figure 11 illustrates a typical
external reference configuration.

FIGURE 11. EXTERNAL REFERENCE CONFIGURATION
Outputs
The outputs IOUT and IOUT are complementary current
outputs. Current is steered to either IOUT or IOUT in proportion
to the digital input code. The sum of the two currents is always
equal to the full scale current minus one LSB. The current
output can be converted to a voltage by using a load resistor.
Both current outputs should have the same load resistor (64Ω
typically). By using a 64Ω load on the output, a 50Ω effective
output resistance (ROUT) is achieved due to the 227Ω (±15%)
parallel resistance seen looking back into the output. This is the
nominal value of the R2R ladder of the DAC. The 50Ω output is
needed for matching the output with a 50Ω line. The load
resistor should be chosen so that the effective output resistance
(ROUT) matches the line resistance.
8
The output voltage is:
VOUT = IOUT x ROUT.
IOUT is defined in the reference section. IOUT is not trimmed
to 12 bits, so it is not recommended that it be used in
conjunction with IOUT in a differential-to-single-ended
application. The compliance range of the output is from 1.25V to 0V, with a 1VP-P voltage swing allowed within this
range.

Settling Time
The settling time of the HI5735 is measured as the time it
takes for the output of the DAC to settle to within a ±1/2 LSB
error band of its final value during a full scale (code 0000...
to 1111.... or 1111... to 0000...) transition. All claims made by
Intersil with respect to the settling time performance of the
HI5735 have been fully verified by the National Institute of
Standards and Technology (NIST) and are fully traceable.
Glitch
The output glitch of the HI5735 is measured by summing the
area under the switching transients after an update of the
DAC. Glitch is caused by the time skew between bits of the
incoming digital data. Typically, the switching time of digital
inputs are asymmetrical, meaning that the turn off time is
faster than the turn on time (TTL designs). Unequal delay
paths through the device can also cause one current source
to change before another. In order to minimize this, the
Intersil HI5735 employes an internal register, just prior to the
current sources, which is updated on the clock edge. Lastly,
the worst case glitch on traditional D/A converters usually
occurs at the major transition (i.e., code 2047 to 2048).
However, due to the split architecture of the HI5735, the
glitch is moved to the 255 to 256 transition (and every
subsequent 256 code transitions thereafter). This split R/2R
segmented current source architecture, which decreases the
amount of current switching at any one time, makes the
glitch practically constant over the entire output range. By
making the glitch a constant size over the entire output
range, this effectively integrates this error out of the end
application.
In measuring the output glitch of the HI5735 the output is
terminated into a 64Ω load. The glitch is measured at any
one of the current cell carry (code 255 to 256 transition or
any multiple thereof) throughout the DACs output range.
The glitch energy is calculated by measuring the area under
the voltage-time curve. Figure 13 shows the area considered
HI5735
as glitch when changing the DAC output. Units are typically
specified in picoVolt-seconds (pV-s).

Integral Linearity Error, INL, is the measure of the worst
case point that deviates from a best fit straight line of data
values along the transfer curve.
Differential Linearity Error, DNL, is the measure of the
error in step size between adjacent codes along the
converter’s transfer curve. Ideally, the step size is 1 LSB from
one code to the next, and the deviation from 1 LSB is known
as DNL. A DNL specification of greater than -1 LSB
guarantees monotonicity.

Bipolar Applications
Output Voltage Small Scale Settling Time, is the time
required from the 50% point on the clock input for a 100mV
step to settle within an 1/2 LSB error band. This is used by
applications reconstructing highly correlated signals such as
sine waves with more than 5 points per cycle.

Differential Gain, ∆AV, is the gain error from an ideal sine

FIGURE 13. MEASURING GLITCH ENERGY
To convert the output of the HI5735 to a bipolar 4V swing, the
following applications circuit is recommended. The reference
can only provide 125µA of drive, so it must be buffered to
create the bipolar offset current needed to generate the -2V
output with all bits “off”. The output current must be converted
to a voltage and then gained up and offset to produce the
proper swing. Care must be taken to compensate for the
voltage swing and error.
Differential Phase, ∆Φ, is the phase error from an ideal sine
wave.
Signal to Noise Ratio, SNR, is the ratio of a fundamental to
the noise floor of the analog output. The first 5 harmonics
are ignored, and an output filter of 1/2 the clock frequency is
used to eliminate alias products.
Total Harmonic Distortion, THD, is the ratio of the DAC
output fundamental to the RMS sum of the harmonics. The
first 5 harmonics are included, and an output filter of 1/2 the
clock frequency is used to eliminate alias products.

Intermodulation Distortion, IMD, is the measure of the
sum and difference products produced when a two tone
input is driven into the D/A. The distortion products created
will arise at sum and difference frequencies of the two tones.
IMD can be calculated using the following equation:
20Log (RMS of Sum and Difference Distortion Products)
IMD = ------------------------------------------------------------------------------------------------------------------------------------------------------- .
