Product details
Overview
ADC08DJ3200AAV from Texas Instruments is an 8-bit, RF-sampling analog-to-digital converter optimized for direct RF digitization in satellite communications and phased-array radar systems. It delivers up to 6.4 GSPS in single-channel mode or 3.2 GSPS in dual-channel mode, with 8.0 GHz analog input bandwidth (–3 dB) and usable frequency response beyond 10 GHz. Its JESD204B subclass-1 interface supports up to 16 lanes at 12.8 Gbps per lane.
For engineers reviewing the ADC08DJ3200AAV datasheet, ADC08DJ3200AAV pinout, ADC08DJ3200AAV application, or ADC08DJ3200AAV equivalent, key selection criteria include RF sampling capability above 10 GHz, deterministic latency via JESD204B subclass-1, noiseless 19-fs aperture delay adjustment, and dual-mode channel configuration flexibility for wide instantaneous bandwidth or high channel count architectures.
Technical Context
The ADC08DJ3200AAV implements a time-interleaved pipeline architecture with on-chip buffered analog inputs and programmable full-scale voltage (0.8 VPP, default). Its dual-channel operation splits the 6.4-GSPS core into two synchronized 3.2-GSPS streams with independent analog inputs (INA±/INB±), enabling MIMO or I/Q sampling without external demultiplexing.
It integrates JESD204B subclass-1 serializer with automatic SYSREF timing calibration and timestamp marking, supporting deterministic latency across multi-device systems. The noiseless TAD adjustment (19-fs steps, temperature/voltage invariant) enables precise inter-ADC synchronization critical for beamforming and coherent signal processing.
Key Specifications

FAQ
What is the maximum usable input frequency range for the ADC08DJ3200AAV?
The ADC08DJ3200AAV supports a usable input frequency range exceeding 10 GHz, with a full-power analog input bandwidth of 8.0 GHz (–3 dB point). This enables direct RF sampling of L-band (1–2 GHz), S-band (2–4 GHz), C-band (4–8 GHz), and X-band (8–12 GHz) signals without analog downconversion, as confirmed in the device's Typical Characteristics and Description sections.
Does the ADC08DJ3200AAV support JESD204C or only JESD204B?
The ADC08DJ3200AAV supports JESD204B subclass 0 and subclass 1 only; it does not implement JESD204C. Subclass-1 compliance ensures deterministic latency and multi-device synchronization, which is essential for phased-array radar and MIMO systems. The datasheet explicitly states JESD204B support and makes no mention of JESD204C functionality for ADC08DJ3200AAV.
Can the ADC08DJ3200AAV operate in single-channel mode with only one analog input enabled?
Yes, the ADC08DJ3200AAV can operate in single-channel mode using only INA± (pins A4/A5), achieving up to 6.4 GSPS. In this configuration, INB± remains unused, and the device internally processes the full 6.4-GSPS stream from Channel A. The datasheet recommends INA± for optimal performance in single-channel mode, and all AC specifications (e.g., ENOB, SFDR) are validated under this condition for ADC08DJ3200AAV.
What power supplies are required for the ADC08DJ3200AAV?
The ADC08DJ3200AAV requires three distinct supply domains: 1.9-V analog (VA19), 1.1-V analog (VA11), and 1.1-V digital (VD11). VA19 powers high-speed analog circuitry including the sampler and buffer; VA11 supplies the analog front-end bias networks; VD11 powers the JESD204B serializer and digital logic. Each supply has separate dedicated balls and must be independently filtered and decoupled per the layout guidelines in the ADC08DJ3200AAV datasheet.
How does the noiseless aperture delay (TAD) adjustment function in the ADC08DJ3200AAV?
The noiseless aperture delay (TAD) adjustment in ADC08DJ3200AAV provides 19-fs resolution delay steps that are invariant to temperature and supply voltage variations. It operates digitally via register control and adjusts the effective sampling instant relative to the CLK± input without introducing jitter or noise-enabling precise inter-ADC timing alignment in multi-device systems such as radar arrays. This feature is implemented entirely within the ADC08DJ3200AAV silicon and requires no external components.
