Analog Devices Inc. AD9411BSV-170

Overview

AD9411BSV-170 from Analog Devices is a 10-bit, 170 MSPS monolithic pipeline analog-to-digital converter optimized for wideband carrier and broadband systems. It features LVDS outputs, on-chip track-and-hold and reference, 700 MHz full-power analog bandwidth, 3.3 V single-supply operation, and delivers 60 dB SNR at 70 MHz input frequency - deployed in radar subsystems requiring high dynamic range digitization.

For engineers reviewing the AD9411BSV-170 datasheet, AD9411BSV-170 pinout, AD9411BSV-170 application, or AD9411BSV-170 equivalent, key selection criteria include sampling rate (170 MSPS), LVDS output compatibility with FPGAs, ENOB of 9.8 bits at 70 MHz, differential clock interface (LVPECL), and industrial temperature range (–40°C to +85°C) support.

Technical Context

The AD9411BSV-170 implements a 10-bit pipeline ADC core with integrated track-and-hold and scalable internal reference. Its LVDS digital outputs support both twos complement and offset binary formats, and it includes a dedicated data clock output (DCO±) to synchronize capture timing in high-speed FPGA interfaces.

It uses a differential LVPECL-compatible clock input (CLK±), supports dual input voltage ranges (1.536 V or 0.766 V p-p differential), and incorporates a clock duty cycle stabilizer. The device operates across –40°C to +85°C and is fabricated in an advanced BiCMOS process for low jitter (0.25 ps rms aperture uncertainty) and stable performance at 170 MSPS.

Key Specifications

Pinout & Package

AD9411BSV-170 is housed in a 100-lead e-PAD TQFP package (exposed heat slug electrically connected to AGND) rated for –40°C to +85°C operation. The conductive slug must be soldered to a solid ground plane to maintain junction temperature within limits under full load.

FAQ

What is the maximum analog input frequency supported by the AD9411BSV-170?

The AD9411BSV-170 has a full-power analog bandwidth of 700 MHz, meaning it maintains specified dynamic performance (e.g., SNR ≥60 dB) for input frequencies up to 700 MHz. This allows direct undersampling of UHF-band signals without external anti-alias filtering in many IF-sampling architectures. Performance metrics such as SFDR and ENOB are guaranteed up to 70 MHz at 170 MSPS per datasheet Table 2, but usable bandwidth extends significantly higher.

Does the AD9411BSV-170 require external components for basic operation?

Yes - the AD9411BSV-170 requires external components for stable operation: a 3.74 kΩ resistor from LVDSBIAS to ground to set LVDS output current, proper decoupling capacitors on AVDD/DRVDD (per datasheet Figure 21 layout guidelines), and controlled-impedance routing for CLK± and DCO±. The internal reference eliminates need for external VREF, but external reference mode (via SENSE) requires a precision 1.23 V source.

How does the AD9411BSV-170 handle input overrange conditions?

The AD9411BSV-170 provides a differential LVDS out-of-range (OR±) output that asserts when the analog input exceeds the selected full-scale range (1.536 V or 0.766 V p-p, set by S5). This flag updates within one conversion cycle and recovers in exactly one cycle after input returns within range - enabling deterministic AGC response in real-time signal processing pipelines using the AD9411BSV-170.

Can the AD9411BSV-170 interface directly with Xilinx Kintex-7 FPGA banks?

Yes - the AD9411BSV-170's LVDS outputs (D0±–D9±, OR±, DCO±) are fully compatible with Xilinx Kintex-7 FPGA I/O banks configured for LVDS_25 standards. The 247–454 mV differential swing and 1.125–1.375 V common-mode voltage meet Xilinx's LVDS input specifications. No level shifters or terminators are needed beyond the FPGA's internal 100 Ω differential termination enabled in IOSTANDARD settings for the AD9411BSV-170 interface.

What thermal management is required for continuous operation of the AD9411BSV-170 at 170 MSPS?

The AD9411BSV-170 dissipates 1.27 W typical at 170 MSPS and requires attachment of its exposed e-PAD to a solid internal ground plane. With the heat slug soldered, θJA drops to 25°C/W (vs. 32°C/W unsoldered), limiting junction temperature rise to ~32°C above ambient. For operation at +85°C ambient, this keeps junction temperature at ~117°C - well below the 150°C absolute maximum. Thermal vias under the pad and copper pour on adjacent layers are strongly recommended.
