Data Sheet
FEATURES
FUNCTIONAL BLOCK DIAGRAM
The AD9371 is a highly integrated, wideband RF transceiver
offering dual channel transmitters and receivers, integrated
synthesizers, and digital signal processing functions. The IC
delivers a versatile combination of high performance and low
power consumption required by 3G/4G micro and macro BTS
equipment in both FDD and TDD applications. The AD9371
operates from 300 MHz to 6000 MHz, covering most of the
licensed and unlicensed cellular bands. The IC supports receiver
bandwidths up to 100 MHz. It also supports observation receiver
and transmit synthesis bandwidths up to 250 MHz to
accommodate digital correction algorithms.
The transceiver consists of wideband direct conversion signal
paths with state-of-the-art noise figure and linearity. Each complete
receiver and transmitter subsystem includes dc offset correction,
quadrature error correction (QEC), and programmable digital
filters, eliminating the need for these functions in the digital
baseband. Several auxiliary functions such as an auxiliary analogto-digital converter (ADC), auxiliary digital-to-analog converters
(DACs), and general-purpose input/outputs (GPIOs) are integrated
to provide additional monitoring and control capability.
An observation receiver channel with two inputs is included to
monitor each transmitter output and implement interference
mitigation and calibration applications. This channel also connects
to three sniffer receiver inputs that can monitor radio activity in
different bands.

JESD204B digital interface
Figure 1.
The high speed JESD204B interface supports lane rates up to
6144 Mbps. Four lanes are dedicated to the transmitters and four
lanes are dedicated to the receiver and observation receiver channels.
The fully integrated phase-locked loops (PLLs) provide high
performance, low power fractional-N frequency synthesis for
the transmitter, the receiver, the observation receiver, and the
clock sections. Careful design and layout techniques provide the
isolation demanded in high performance base station applications.
All voltage controlled oscillator (VCO) and loop filter components
are integrated to minimize the external component count.
A 1.3 V supply is required to power the core of the AD9371, and
a standard 4-wire serial port controls it. Other voltage supplies
provide proper digital interface levels and optimize transmitter
and auxiliary converter performance. The AD9371 is packaged in a
12 mm × 12 mm, 196-ball chip scale ball grid array (CSP_BGA).

Synthesis bandwidth (BW) is the extended bandwidth used by digital correction algorithms to measure conditions and generate compensation.
3
Quadrature error correction (QEC) is the system for minimizing quadrature images of a desired signal.
4
Local oscillator leakage (LOL) is a measure of the amount of the LO signal that is passed from a mixer with the desired signal.
5
Adjacent channel level reduction (ACLR) is a measure of the amount of power from the desired signal leaking into an adjacent channel.
6
dBFS represents the ratio of the actual output signal to the maximum possible output level for a continuous wave output signal at the given RF attenuation setting.
7
Continuous wave (CW) is a single frequency signal.
8
Note that the input signal power limit does not correspond to 0 dBFS at the digital output because of the nature of the continuous time Σ-Δ ADCs. Unlike the hard
clipping characteristic of pipeline ADCs, these converters exhibit a soft overload behavior when the input approaches the maximum level.
9
Signal-to-noise ratio is limited by the baseband quantization noise.

AD9371
THEORY OF OPERATION
The AD9371 is a highly integrated RF transceiver that can be
configured for a wide range of applications. The device integrates
all the RF, mixed-signal, and digital blocks necessary to provide
transmit and receive functions in a single device. Programmability
allows the two receiver channels and two transmitter channels
to be used in TDD and FDD systems for 3G and 4G cellular
standards.
The observation receiver channel has two inputs for use in
monitoring the transmitter outputs. This channel has a wide
channel bandwidth that receives the entire transmit band and
feeds it back to the digital section for error correction purposes.
In addition, three sniffer receiver inputs can monitor different
radio frequency bands (one at a time). These channels share the
baseband ADC and digital processing with the two ORx inputs.
The AD9371 contains four high speed serial interface links for
the transmit chain and four high speed serial interface links
shared by the Rx, ORx, and SnRx channels (JESD204B,
Subclass 1 compliant), providing a low pin count and reliable
data interface to a field-programmable gate array (FPGA) or
other custom integrated baseband solutions.
The AD9371 also provides self calibration for dc offset, LO
leakage, and quadrature error correction using an integrated
microcontroller core to maintain a high performance level
under varying temperatures and input signal conditions. Firmware
is supplied with the device to schedule all calibrations with no
user interaction. The device includes test modes that allows
system designers to debug designs during prototyping and
optimize radio configurations.
TRANSMITTER (Tx)
The AD9371 employs a direct conversion transmitter
architecture consisting of two identical and independently
controlled channels that provide all the digital processing,
mixed signal, and RF blocks necessary to implement a direct
conversion system. Both channels share a common frequency
synthesizer.
The digital data from the JESD204B lanes pass through a fully
programmable 96-tap FIR filter with optional interpolation.
The FIR output is sent to a series of conversion filters that
provide additional filtering and data rate interpolation prior to
reaching the DAC. Each DAC has an adjustable sample rate and
is linear up to full scale.
When converted to baseband analog signals, the in-phase (I) and
quadrature (Q) signals are filtered to remove sampling artifacts,
and then the signals are fed to the upconversion mixers. At the
mixer stage, the I and Q signals are recombined and modulated
onto the carrier frequency for transmission to the output stage.
Each transmit chain provides a wide attenuation adjustment
range with fine granularity to help designers optimize SNR.
RECEIVER (Rx)
The AD9371 contains dual receiver channels. Each Rx channel
is a direct conversion system that contains a programmable
attenuator stage, followed by matched I and Q mixers that
downconvert received signals to baseband for digitization.
To achieve gain control, a programmed gain index map is
implemented. This gain map distributes attenuation among the
various Rx blocks for optimal performance at each power level.
In addition, support is available for both automatic and manual
gain control modes.
The receiver includes Σ-Δ ADCs and adjustable sample rates
that produce data streams from the received signals. The signals
can be conditioned further by a series of decimation filters and
a fully programmable 72-tap FIR filter with additional decimation
settings. The sample rate of each digital filter block is adjustable
by changing the decimation factors to produce the desired
output data rate.
OBSERVATION RECEIVER (ORx)
The ORx operates in a similar manner to the main receivers.
Each input is differential and uses a dedicated mixer. The ORx
inputs share a baseband ADC and baseband section; therefore,
only one can be active at any time. The mixed-signal and digital
section is identical in design and operation to the main receiver
channels. This channel can monitor the Tx channels and
implement error correction functions. It can also be used as a
general-purpose receiver.
SNIFFER RECEIVER (SnRx)
The sniffer receiver provides three differential inputs that can
monitor different frequency bands. Each input has a low noise
amplifier (LNA) that is multiplexed to feed a single mixer. The
output of this mixer stage is multiplexed with the ORx receiver
mixers to feed the same baseband section. The SnRx bandwidth
is limited to 20 MHz. This receiver can also be used as a generalpurpose receiver if the bandwidth and RF performance are
acceptable for a given application.
These receiver inputs also provide an LNA bypass mode that
removes the gain of the LNA when large signals are present.
Note that no requirements for the LNA bypass mode are included
in Table 1; performance specifications are only relative to the
scenario in which the LNA is enabled.
CLOCK INPUT
The AD9371 requires a differential clock connected to the
DEV_CLK_IN+/DEV_CLK_IN− pins. The frequency of the
clock input must be between 10 MHz and 320 MHz, and it must
have very low phase noise because this signal generates the RF
local oscillator and internal sampling clocks.

SYNTHESIZERS
RF PLL
The AD9371 contains three fractional-N PLLs to generate the
RF LOs used by the transmitter, receiver, and observation
receiver. The PLL incorporates an internal VCO and loop filter
that require no external components. The internal VCO LDO
regulators eliminate the need for additional external power
supplies for the PLLs. These regulators only require an external
bypass capacitor for each supply.
manual gain mode, calibration flags, state machine states, and
various receiver parameters are among the outputs that can be
monitored on these pins. In addition, certain pins can be
configured as inputs and used in various functions such as
setting the receiver gain in real time.
The GPIO_3P3_x pins referenced to the VDDA_3P3 supply are
also included in the device and can provide control signals to
the external components such as VGAs or attenuators in the RF
section that typically use a higher reference voltage.
Clock PLL
AUXILIARY CONVERTERS
The AD9371 contains a PLL synthesizer that generates all of the
baseband related clock signals and SERDES clocks. This PLL is
programmed based on the data rate and sample rate requirements
of the system.
Auxiliary ADC Inputs (AUXADC_x)
External LO Inputs
The AD9371 provides two external LO inputs to allow an
external synthesizer to be used with the device. These inputs
must be 2× the desired LO frequency. Note that operation for
the external LO option is limited to a maximum of 4000 MHz.
One input pair is dedicated to the receiver LO generation circuit
and the other input provides the input to the transmitter and
observation receiver LO generation blocks. Note that the
observation receiver can obtain the LO from either the Tx LO
generator block or its own dedicated PLL. When the sniffer
channel is enabled, the LO for this block can only come from
the dedicated internal observation channel PLL.
SERIAL PERIPHERAL INTERFACE (SPI) INTERFACE
The AD9371 uses a SPI to communicate with the baseband
processor (BBP). This interface can be configured as a 4-wire
interface with dedicated receive and transmit ports, or it can be
configured as a 3-wire interface with a bidirectional data
communications port. This bus allows the BBP to set all device
control parameters using a simple address data serial bus protocol.
Write commands follow a 24-bit format. The first bit sets the
bus direction of the bus transfer. The next 15 bits set the address
where data is written. The final eight bits are the data being
transferred to the specific register address.
Read commands follow a similar format with the exception that
the first 16 bits are transferred on the SDIO pin, and the final
eight bits are read from the AD9371, either on the SDO pin in
4-wire mode or on the SDIO pin in 3-wire mode.
GPIO_x AND GPIO_3P3_x PINS
The AD9371 general-purpose input/output signals referenced
to the VDD_IF supply can be configured for numerous functions.
Some of these pins, when configured as outputs, are used by the
BBP as real-time signals to provide a number of internal settings
and measurements. This configuration allows the BBP to monitor
receiver performance in different situations. A pointer register
selects what information is output to these pins. Signals used for
The AD9371 contains an auxiliary ADC that is multiplexed to four
input pins (AUXADC_0 through AUXADC_3). This block can
monitor system voltages without adding additional components.
The auxiliary ADC is 12 bits with an input voltage range of 0.05 V
to VDDA_3P3 − 0.25 V. When enabled, the auxiliary ADC is
free running. Software reads of the output value provide the last
value latched at the ADC output.
Auxiliary DACs (AUXDAC_x)
The AD9371 contains 10 identical auxiliary DACs (AUXDAC_0
to AUXDAC_9) that can supply bias voltages, analog control
voltages, or other system functionality. The inputs of these auxiliary
DACs (AUXDAC_0 to AUXDAC_9) are multiplexed with the
GPIO_3P3_x pins according to Table 7. The auxiliary DACs are
10 bits and have an output voltage range of approximately 0.5 V
to VDDA_3P3 − 0.3 V and have a current drive of 10 mA.

JESD204B DATA INTERFACE
The digital data interface for the AD9371 uses JEDEC Standard
JESD204B Subclass 1. The serial interface operates at speeds of
up to 6144 Mbps. The benefits of the JESD204B interface include a
reduction in required board area for data interface routing and
smaller package options due to the need for fewer pins. Digital
filtering is included in all receiver and transmitter paths to provide
proper signal conditioning and sampling rates to meet the
JESD204B data requirements. Examples of the digital filtering
configurations for the Tx and Rx paths are shown in Figure 240
and Figure 241, respectively.

POWER SUPPLY SEQUENCE
Table 9. Dual-Function Boundary Scan Test Pins
The AD9371 requires a specific power-up sequence to avoid
undesired power-up currents. The optimal power-on sequence
starts the process by powering up the VDIG and the VDDA_1P3
(analog) supplies simultaneously. If they cannot power up
simultaneously, the VDIG supply must power up first. The
VDDA_3P3, VDDA_1P8, and JESD_VTT_DES supplies
must then power up after the VDIG and VDDA_1P3 supplies.
Note that the VDD_IF supply can power up at any time. It is
also recommended to toggle the RESET signal after power has
stabilized prior to configuration. Follow the reverse order of
the power-up sequence to power-down.

JTAG BOUNDARY SCAN
The AD9371 provides support for a JTAG boundary scan.
There are five dual-function pins associated with the JTAG
interface. These pins, listed in Table 9, are used to access the
on-chip test access port. To enable the JTAG functionality,
set the GPIO_0 through GPIO_3 pins according to Table 10
depending on how the desired JESD204B sync pin (that is,
SYNCINB0+, SYNCINB0−, SYNCINB1+, SYNCINB1−,
SYNCBOUTB0+, or SYNCBOUTB0−) is configured in the
software (LVDS or CMOS mode). Pull the TEST pin high to
enable the JTAG mode.
