Product details
Overview
AD9375BBCZ from Analog Devices is a highly integrated dual-channel RF transceiver with observation and sniffer receivers, operating from 300 MHz to 6000 MHz. It delivers 100 MHz Rx bandwidth, 250 MHz ORx bandwidth, JESD204B interface (6.144 Gbps/lane), and on-chip digital predistortion (DPD) for PA linearization in 3G/4G small cell base stations.
For engineers reviewing the AD9375BBCZ datasheet, AD9375BBCZ pinout, AD9375BBCZ application, or AD9375BBCZ equivalent, this page provides verified functional identity, confirmed RF performance across bands (700 MHz–5.5 GHz), validated DPD capability up to 40 MHz signal BW, exact 196-ball CSP_BGA package mapping, and two field-validated alternative transceivers for FDD/TDD infrastructure designs.
Technical Context
The AD9375BBCZ integrates four independent fractional-N RF synthesizers (Tx, Rx, ORx, clock), each supporting 300–6000 MHz tuning with 2.3 Hz frequency step and <0.75°rms integrated phase noise at 5500 MHz. Its direct-conversion architecture includes full dc offset correction, quadrature error correction (QEC), and programmable pFIR filters per channel.
It implements a fully embedded DPD actuator and adaptation engine enabling high-efficiency PA use while reducing JESD204B lane count; the observation receiver supports two differential inputs (ORX1±, ORX2±) with 250 MHz bandwidth and 60 dB alias rejection, and the sniffer receiver provides three inputs (SNRXA±, SNRXB±, SNRXC±) for wideband spectrum monitoring.

Equivalent & Alternatives
The following parts are listed as comparable options for similar RF transceiver applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9371BBCZ | Single Tx/Rx channel, no ORx or SnRx; 122.88 MSPS max data rate vs. AD9375BBCZ's 245.76 MSPS; lacks integrated DPD engine. | Targeted at lower-cost 2T2R small cells without real-time DPD or wideband observation needs. | Select AD9371BBCZ only when ORx/SnRx functionality and on-chip DPD are not required-reduces cost and complexity but sacrifices calibration flexibility. |
| ADRV9009BBCZ | Successor generation: wider 200 MHz Rx BW, 450 MHz ORx BW, improved NF (11.5 dB @ 700 MHz), and enhanced DPD convergence speed. | Designed for next-gen 5G NR and massive MIMO systems requiring higher instantaneous bandwidth and faster adaptation. | Choose ADRV9009BBCZ for new 5G deployments needing >100 MHz signal BW or tighter EVM specs; AD9375BBCZ remains optimal for mature 4G small cell production. |
Compared with AD9371BBCZ, AD9375BBCZ adds dual-channel observation capability and embedded DPD-critical for carrier-grade calibration-while ADRV9009BBCZ extends bandwidth and phase noise performance for 5G, making AD9375BBCZ the balanced choice for cost-sensitive 4G infrastructure with advanced linearization needs.

FAQ
What is the maximum observation receiver (ORx) bandwidth supported by the AD9375BBCZ?
The AD9375BBCZ supports an observation receiver bandwidth of up to 250 MHz, enabling wideband capture of Tx output signals for digital predistortion (DPD) feedback and calibration. This bandwidth accommodates digital correction algorithms requiring extended spectral coverage beyond the primary Tx signal bandwidth, and is validated across the full 300–6000 MHz operating range per the AD9375 Rev. 0 datasheet, Page 6.
Does the AD9375BBCZ include an integrated digital predistortion (DPD) engine?
Yes, the AD9375BBCZ contains a fully integrated, low-power DPD actuator and adaptation engine dedicated to PA linearization. It supports signal bandwidths up to 40 MHz (e.g., two adjacent 20 MHz LTE carriers) and eliminates the need for external DPD hardware, reducing FPGA resource usage and JESD204B lane count. This capability is documented in the General Description section and Table 1 of the AD9375 Rev. 0 datasheet.
What package type and dimensions does the AD9375BBCZ use?
The AD9375BBCZ is packaged in a 12 mm × 12 mm, 196-ball chip scale ball grid array (CSP_BGA) with exposed thermal pad. This package is specified in the Outline Dimensions section (Page 61) and Absolute Maximum Ratings table (Page 14) of the AD9375 Rev. 0 datasheet, and supports standard reflow profiles per JEDEC JESD20.
Can the AD9375BBCZ operate in both FDD and TDD modes?
Yes, the AD9375BBCZ supports both frequency division duplex (FDD) and time division duplex (TDD) operation. Its architecture includes independent fractional-N synthesizers for Tx, Rx, and ORx paths, allowing simultaneous or time-multiplexed operation with configurable LO frequencies and timing alignment. This dual-mode capability is explicitly stated in the Features and General Description sections of the AD9375 Rev. 0 datasheet.
How many sniffer receiver inputs does the AD9375BBCZ provide, and what is their purpose?
The AD9375BBCZ includes three differential sniffer receiver inputs (SNRXA±, SNRXB±, SNRXC±), each supporting 20 MHz bandwidth and 5 dB noise figure at 700 MHz. These inputs enable concurrent wideband spectrum monitoring across multiple bands-for interference detection, dynamic spectrum access, or regulatory compliance scanning-without impacting primary Tx/Rx operation.
