GENERAL DESCRIPTION
The AD9410 is a 10-bit monolithic sampling analog-to-digital
converter with an on-chip track-and-hold circuit and is optimized for high-speed conversion and ease of use. The product
operates at a 210 MSPS conversion rate, with outstanding
dynamic performance over its full operating range.
The ADC requires a 5.0 V and 3.3 V power supply and up to a
210 MHz differential clock input for full performance operation.
No external reference or driver components are required for many
applications. The digital outputs are TTL/CMOS-compatible,
and separate output power supply pins also support interfacing
with 3.3 V logic.
The clock input is differential and TTL/CMOS-compatible. The
10-bit digital outputs can be operated from 3.3 V (2.5 V to 3.6 V)
supplies. Two output buses support demultiplexed data up to
105 MSPS rates, and binary or two’s complement output coding
format is available. A data sync function is provided for timingdependent applications. An output clock simplifies interfacing to
external logic. The output data bus timing is selectable for parallel
or interleaved mode, allowing for flexibility in latching output data.
Fabricated on an advanced BiCMOS process, the AD9410
is available in an 80-lead surface-mount plastic package
(PowerQuad
®
2) specified over the industrial temperature range
(–40°C to +85°C).

APPLICATION NOTES
THEORY OF OPERATION
The AD9410 architecture is optimized for high speed and ease
of use. The analog inputs drive an integrated high bandwidth
track-and-hold circuit that samples the signal prior to quantization by the flash 10-bit core. For ease of use the part includes
an onboard reference and input logic that accepts TTL, CMOS,
or PECL levels.
USING THE AD9410
ENCODE Input
Any high-speed A/D converter is extremely sensitive to the
quality of the sampling clock provided by the user. A Track/Hold
circuit is essentially a mixer, and any noise, distortion, or timing
jitter on the clock will be combined with the desired signal at the
A/D output. For that reason, considerable care has been taken
in the design of the ENCODE input of the AD9410, and the
user is advised to give commensurate thought to the clock source.
To limit SNR degradation to less than 1 dB, a clock source with
less than 1.25 ps rms jitter is required for sampling at Nyquist.
(Valpey Fisher VF561 is an example.) Note that required jitter
accuracy is a function of input frequency and amplitude. Consult
Analog Devices’ application note AN-501, “Aperture Uncertainty and ADC System Performance,” for more information.
The ENCODE input is fully TTL/CMOS-compatible. The
clock input can be driven differentially or with a single-ended
signal. Best performance will be obtained when driving the clock
differentially. Both ENCODE inputs are self-biased to 1/3 × V
by a high impedance resistor divider. (See Equivalent Circuits
section.) Single-ended clocking, which may be appropriate for
lower frequency or nondemanding applications, is accomplished
by driving the ENCODE input directly and placing a 0.1 µF
capacitor at ENCODE.

Figure 10. Driving Single-Ended Encode Input at
TTL/CMOS Levels
An example where the clock is obtained from a PECL driver is
shown in Figure 11. Note that the PECL driver is ac-coupled to
the ENCODE inputs to minimize input current loading. The
AD9410 can be dc-coupled to PECL logic levels resulting in the
ENCODE input currents increasing to approximately 8 mA
typically. This is due to the difference in dc bias between the
ENCODE inputs and a PECL driver. (See Equivalent Circuits section.)

Analog Input
The analog input to the AD9410 is a differential buffer. For
best dynamic performance, impedances at A
and AIN should
IN
match. The analog input has been optimized to provide superior
wideband performance and requires that the analog inputs be
driven differentially. SNR and SINAD performance will degrade
significantly if the analog input is driven with a single-ended
signal. A wideband transformer such as Minicircuits ADT1-1WT
can be used to provide the differential analog inputs for applications that require a single-ended-to-differential conversion. Both
analog inputs are self-biased by an on-chip resistor divider to a
nominal 3 V. (See Equivalent Circuits section.)
Special care was taken in the design of the Analog Input section
of the AD9410 to prevent damage and corruption of data when the
input is overdriven. The nominal input range is 1.5 V diff p-p.
The nominal differential input range is 768 mV p-p × 2.

Digital Outputs
The digital outputs are TTL/CMOS-compatible for lower power
consumption. The outputs are biased from a separate supply
(V
), allowing easy interface to external logic. The outputs are
DD
CMOS devices which will swing from ground to V
(with no
DD
dc load). It is recommended to minimize the capacitive load the
ADC drives by keeping the output traces short (<1 inch, for a
total C
< 5 pF). It is also recommended to place low value
LOAD
(20 Ω) series damping resistors on the data lines to reduce switching transient effects on performance.
Clock Outputs (DCO, DCO)
The input ENCODE is divided by two and available off-chip at
DCO and DCO. These clocks can facilitate latching off-chip,
providing a low skew clocking solution (see timing diagram).
These clocks can also be used in multiple AD9410 systems to
synchronize the ADCs. Depending on application, DCO or
DCO can be buffered and used to drive the DS inputs on a
second AD9410, ensuring synchronization. The on-chip clock
buffers should not drive more than 5 pF–7 pF of capacitance to
limit switching transient effects on performance.
Voltage Reference
A stable and accurate 2.5 V voltage reference is built into the
AD9410 (VREF OUT). The input range can be adjusted by
varying the reference voltage. No appreciable degradation in
performance occurs when the reference is adjusted ±5%. The fullscale range of the ADC tracks reference voltage changes linearly
within the ±5% tolerance.

AD9410
Timing
The AD9410 provides latched data outputs, with six pipeline
delays in interleaved mode (see Figure 1). In parallel mode, the
A Port has one additional cycle of latency added on-chip to line
up transitions at the data ports—resulting in a latency of seven
cycles for the A Port. The length of the output data lines and
loads placed on them should be minimized to reduce transients
within the AD9410; these transients can detract from the
converter’s dynamic performance.
The minimum guaranteed conversion rate of the AD9410 is
100 MSPS. At internal clock rates below 100 MSPS, dynamic
performance may degrade. Note that lower effective sampling
rates can be obtained simply by sampling just one output port—
decimating the output by two. Lower sampling frequencies can
also be accommodated by restricting the duty cycle of the clock
such that the clock high pulsewidth is a maximum of 5 ns.
EVALUATION BOARD
The AD9410 evaluation board offers an easy way to test the
AD9410. The board requires an analog input, clock, and 3 V,
5 V power supplies. The digital outputs and output clocks are
available at a standard 80-lead header P2, P3. The board has
several different modes of operation, and is shipped in the following configuration:
•
Output Timing = Parallel Mode
•
Output Format = Offset Binary
•
Internal Voltage Reference
Power Connector
Power is supplied to the board via detachable 4-pin power strips
P1, P4, P5.
3.3 VA – Analog Supply (3.3 V)
5 V – Analog Supply (5 V)
Analog Inputs
The evaluation board accepts a 1.5 V p-p analog input signal
centered at ground at SMB J8. This input is terminated to 50 Ω
on the board at the transformer secondary, but can be terminated at the SMB if an alternative termination is desired. The
input is ac-coupled prior to the transformer. The transformer is
band limited to frequencies between approximately 1 MHz and
400 MHz.
Encode
The encode input to the board is at SMB connector J1. The
input is terminated on the board with 50 Ω to ground. The
(>0.5 V p-p) input is ac-coupled and drives a high-speed
differential line receiver (MC10EL16). This receiver provides
sub- nanosecond rise times at its outputs—a requirement for
the ADC clock inputs for optimum performance. The EL16
outputs are PECL levels and are ac-coupled to meet the commonmode dc levels at the AD9410 encode inputs.
Data Sync (DS)
The Data Sync input, DS, can be used in applications requiring that a given sample will appear at a specific output Port A or
B. When DS is held high, the ADC data outputs and clock do notswitch and are held static. Synchronization is accomplished by the
assertion (falling edge) of DS, within the timing constraints
and T

SDS
synchronization T

SDS
the analog value at that point in time will be digitized and available at Port B six cycles later (interleaved mode). The very next
sample, N+1, will be sampled by the next rising encode edge and
available at Port A six cycles after that encode edge (interleaved
mode). In dual parallel mode the A Port has a seven cycle latency,
the B Port has a six cycle latency, but data is available at the
same time.
REFERENCE
The AD9410 has an on-chip reference of 2.5 V available at
REF
to the REF
(Pin 4). Most applications will simply tie this output
OUT
input (Pin 5). This is accomplished by placing a
IN
jumper at E1, E6. An external reference can be used placing a
jumper at E1, E3.
Output Timing
The chip has two timing modes (see timing diagram). Interleaved mode is selected by Jumper E11, E7. Parallel mode is
selected by Jumper E11, E14.
Data Format Select
Data Format Select sets the output data format that the ADC
outputs. Setting DFS (Pin 79) low at E12, E10 sets the output
format to be offset binary; setting DFS high at E12, E16 sets the
output to be two’s complement.
DS Pin
The DS, DS inputs are available at SMB connectors J9X and
J10X. The board is shipped with DS pulled to ground by R26.
DS is floating (R25X is not placed).
DAC Outputs
Each channel is reconstructed by an on-board dual channel
DAC, an AD9751 to assist in debug. The performance of the
DAC has not been optimized and will not give an accurate
measure of the full performance of the ADC. It is a current
output DAC with on-board 50 Ω termination resistors. The
outputs are available at J3 and J4.

TROUBLESHOOTING
If the board does not seem to be working correctly, try the
following:
•
Verify power at IC pins.
•
Check that all jumpers are in the correct position for the
desired mode of operation.
•
Verify VREF is at 2.5 V.

• Try running encode clock and analog input at low speeds
(10 MSPS/1 MHz) and monitor latch outputs, DAC outputs,
and ADC outputs for toggling.

NOTE
The AD9410 has a conductive heat slug to help dissipate heat
and ensure reliable operation of the device over the full industrial temperature range. The slug is exposed on the bottom of
the package. It is recommended that no PCB traces or vias be
located under the package that could come in contact with the
conductive slug. Attaching the slug to a ground plane while not
required in most applications will reduce the junction temperature of the device which may be beneficial in high temperature
environments.
