GENERAL DESCRIPTION
PRODUCT HIGHLIGHTS
The AD9626 is a 12-bit monolithic sampling analog-to-digital
converter optimized for high performance, low power, and ease
of use. The product operates at up to a 250 MSPS conversion
rate and is optimized for outstanding dynamic performance in
wideband carrier and broadband systems. All necessary functions, including a track-and-hold (T/H) and voltage reference,
are included on the chip to provide a complete signal
conversion solution.
1.
High Performance—Maintains 64.9 dBFS SNR @ 250 MSPS
with a 70 MHz input.
2.
Low Power—Consumes only 364 mW @ 250 MSPS.
3.
Ease of Use—CMOS output data and output clock signal
allow interface to current FPGA technology. The on-chip
reference and sample-and-hold provide flexibility in
system design. Use of a single 1.8 V supply simplifies
system power supply design.
4.
Serial Port Control—Standard serial port interface supports
various product functions, such as data formatting, clock
duty cycle stabilizer, power-down, gain adjust, and output
test pattern generation.
5.
Pin-Compatible Family—10-bit pin-compatible family
offered as the AD9601.
The ADC requires a 1.8 V analog voltage supply and a differential clock for full performance operation. The digital outputs are
CMOS compatible and support either twos complement, offset
binary format, or Gray code. A data clock output is available for
proper output data timing.
Fabricated on an advanced CMOS process, the AD9626 is
available in a 56-lead LFCSP, specified over the industrial
temperature range (−40°C to +85°C).

Stresses above those listed under Absolute Maximum Ratings
may cause permanent damage to the device. This is a stress
rating only; functional operation of the device at these or any
other conditions above those indicated in the operational
section of this specification is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect
device reliability.
THERMAL RESISTANCE
The exposed paddle must be soldered to the ground plane for
the LFCSP package. Soldering the exposed paddle to the
customer board increases the reliability of the solder joints,
maximizing the thermal capability of the package.

°C/W
Typical θJA and θJC are specified for a 4-layer board in still air.
Airflow increases heat dissipation, effectively reducing θJA. In
addition, metal in direct contact with the package leads from
metal traces, and through holes, ground, and power planes
reduces the θJA.

THEORY OF OPERATION
ANALOG INPUT AND VOLTAGE REFERENCE
499Ω
An internal differential voltage reference creates positive and
negative reference voltages that define the 1.25 V p-p fixed span
of the ADC core. This internal voltage reference can be adjusted
by means of SPI control. See the AD9626 Configuration Using
the SPI section for more details.

Figure 42. Differential Input Configuration Using the AD8138
At input frequencies in the second Nyquist zone and above, the
performance of most amplifiers may not be adequate to achieve
the true performance of the AD9626. This is especially true in
IF undersampling applications where frequencies in the 70 MHz
to 100 MHz range are being sampled. For these applications,
differential transformer coupling is the recommended input
configuration. The signal characteristics must be considered
when selecting a transformer. Most RF transformers saturate at
frequencies below a few millihertz, and excessive signal power
can also cause core saturation, which leads to distortion.
In any configuration, the value of the shunt capacitor, C, is
dependent on the input frequency and may need to be reduced
or removed.

Optimum performance is achieved while driving the AD9626
in a differential input configuration. For baseband applications,
the AD8138 differential driver provides excellent performance
and a flexible interface to the ADC. The output common-mode
voltage of the AD8138 is easily set to AVDD/2 + 0.5 V, and the
driver can be configured in a Sallen-Key filter topology to
provide band limiting of the input signal.

The analog input to the AD9626 is a differential buffer. For best
dynamic performance, the source impedances driving VIN+
and VIN− should be matched such that common-mode settling
errors are symmetrical. The analog input is optimized to
provide superior wideband performance and requires that the
analog inputs be driven differentially.
A wideband transformer, such as Mini-Circuits® ADT1-1WT,
can 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 1.4 V.

The input stage contains a differential SHA that can be ac- or
dc-coupled. The output-staging block aligns the data, carries
out the error correction, and passes the data to the output
buffers. The output buffers are powered from a separate supply,
allowing adjustment of the output voltage swing. During powerdown, the output buffers go into a high impedance state.

Each stage of the pipeline, excluding the last, consists of a low
resolution flash ADC connected to a switched capacitor DAC
and interstage residue amplifier (MDAC). The residue amplifier
magnifies the difference between the reconstructed DAC output
and the flash input for the next stage in the pipeline. One bit of
redundancy is used in each stage to facilitate digital correction
of flash errors. The last stage simply consists of a flash ADC.
1V p-p

The AD9626 architecture consists of a front-end sample-andhold amplifier (SHA) followed by a pipelined switched capacitor
ADC. The quantized outputs from each stage are combined into
a final 12-bit result in the digital correction logic. The pipelined
architecture permits the first stage to operate on a new input
sample, while the remaining stages operate on preceding
samples. Sampling occurs on the rising edge of the clock.

For optimum performance, the AD9626 sample clock inputs
(CLK+ and CLK−) should be clocked with a differential signal.
This signal is typically ac-coupled into the CLK+ pin and the
CLK− pin via a transformer or capacitors. These pins are biased
internally and require no additional bias.
Figure 45 shows one preferred method for clocking the AD9626.
The low jitter clock source is converted from single-ended to
differential using an RF transformer. The back-to-back Schottky
diodes across the secondary transformer limit clock excursions
into the AD9626 to approximately 0.8 V p-p differential. This
helps prevent the large voltage swings of the clock from feeding
through to other portions of the AD9626 and preserves the fast
rise and fall times of the signal, which are critical to low jitter
performance.

If a low jitter clock is available, another option is to ac couple a
differential PECL signal to the sample clock input pins, as
shown in Figure 46. The AD9510/AD9511/AD9512/AD9513/
AD9514/AD9515 family of clock drivers offers excellent jitter
performance.

In some applications, it is acceptable to drive the sample clock
inputs with a single-ended CMOS signal. In such applications,
CLK+ should be directly driven from a CMOS gate, and the
CLK− pin should be bypassed to ground with a 0.1 μF capacitor
in parallel with a 39 kΩ resistor (see Figure 48). Although the
CLK+ input circuit supply is AVDD (1.8 V), this input is
designed to withstand input voltages up to 3.3 V, making the
selection of the drive logic voltage very flexible.
07099-014
CLOCK INPUT CONSIDERATIONS
Typical high speed ADCs use both clock edges to generate a
variety of internal timing signals. As a result, these ADCs may
be sensitive to the clock duty cycle. Commonly, a 5% tolerance
is required on the clock duty cycle to maintain dynamic performance characteristics. The AD9626 contains a duty cycle
stabilizer (DCS) that retimes the nonsampling edge, providing
an internal clock signal with a nominal 50% duty cycle. This
allows a wide range of clock input duty cycles without affecting
the performance of the AD9626. When the DCS is on, noise
and distortion performance are nearly flat for a wide range of
duty cycles. However, some applications may require the DCS
function to be off. If so, keep in mind that the dynamic range
performance can be affected when operated in this mode. See the
AD9626 Configuration Using the SPI section for more details
on using this feature.
The duty cycle stabilizer uses a delay-locked loop (DLL) to
create the nonsampling edge. As a result, any changes to the
sampling frequency require approximately eight clock cycles
to allow the DLL to acquire and lock to the new rate.

AD9626
Clock Jitter Considerations
High speed, high resolution ADCs are sensitive to the quality of the
clock input. The degradation in SNR for a full-scale input signal
at a given input frequency (fA) due only to aperture jitter (tJ) can
be calculated by
SNR Degradation = 20 × log10[1/2 × π × fA × tJ]
In this equation, the rms aperture jitter represents the root mean
square of all jitter sources, including the clock input, analog input
signal, and ADC aperture jitter specifications. IF undersampling
applications are particularly sensitive to jitter (see Figure 50).
The clock input should be treated as an analog signal in cases
where aperture jitter may affect the dynamic range of the AD9626.
Power supplies for clock drivers should be separated from the
ADC output driver supplies to avoid modulating the clock signal
with digital noise. Low jitter, crystal controlled oscillators make
the best clock sources. If the clock is generated from another
type of source (by gating, dividing, or other methods), it should
be retimed by the original clock at the last step.
Refer to the AN-501 Application Note and the AN-756
Application Note for more in-depth information about jitter
performance as it relates to ADCs (visit www.analog.com).

The off-chip drivers on the AD9626 are CMOS-compatible
output levels. The outputs are biased from a separate supply
(DRVDD), allowing isolation from the analog supply and easy
interface to external logic. The outputs are CMOS devices that
swing from ground to DRVDD (with no dc load). It is recommended to minimize the capacitive load the ADC drives by
keeping the output traces short ( 0.62 + 0.5 LSB

MEMORY MAP
READING THE MEMORY MAP TABLE
RESERVED LOCATIONS
Each row in the memory map table has eight address locations.
The memory map is roughly divided into three sections: chip
configuration register map (Address 0x00 to Address 0x02),
transfer register map (Address 0xFF), and program register map
(Address 0x08 to Address 0x2A).
Undefined memory locations should not be written to other
than their default values suggested in this data sheet. Addresses
that have values marked as 0 should be considered reserved and
have a 0 written into their registers during power-up.
The Addr (Hex) column of the memory map indicates the
register address in hexadecimal, and the Default Value (Hex)
column shows the default hexadecimal value that is already
written into the register, The Bit 7 (MSB) column is the start of
the default hexadecimal value given. For example, Hexadecimal
Address 0x09, clock, has a hexadecimal default value of 0x01.
This means Bit 7 = 0, Bit 6 = 0, Bit 5 = 0, Bit 4 = 0, Bit 3 = 0,
Bit 2 = 0, Bit 1 = 0, and Bit 0 = 1, or 0000 0001 in binary. The
default value enables the duty cycle stabilizer. Overwriting this
default so that Bit 0 = 0 disables the duty cycle stabilizer. For more
information on this and other functions, consult the Interfacing
to High Speed ADCs via SPI user manual at www.analog.com.
Coming out of reset, critical registers are preloaded with default
values. These values are indicated in Table 12. Other registers
do not have default values and retain the previous value when
exiting reset.
DEFAULT VALUES
LOGIC LEVELS
An explanation of various registers follows: “Bit is set” is
synonymous with “bit is set to Logic 1” or “writing Logic 1 for
the bit.” Similarly, “clear a bit” is synonymous with “bit is set to
Logic 0” or “writing Logic 0 for the bit.”
