Analog Devices Inc. AD9250BCPZRL7-170

Overview

AD9250BCPZRL7-170 from Analog Devices is a dual-channel, 14-bit analog-to-digital converter with 170 MSPS sampling rate, JESD204B Subclass 0/1 serial interface, 70.7 dBFS SNR at 185 MHz input, 95 dB channel isolation, and 1.8 V single-supply operation. It serves as the front-end digitizer in wideband IF receivers for wireless infrastructure and test equipment.

For engineers reviewing the AD9250BCPZRL7-170 datasheet, AD9250BCPZRL7-170 pinout, AD9250BCPZRL7-170 application, or AD9250BCPZRL7-170 equivalent, key selection criteria include JESD204B lane configuration (M=2, L=2), 170 MSPS real-time throughput per channel, CML serial output compliance, and support for up to 400 MHz IF sampling frequencies.

Technical Context

The AD9250BCPZRL7-170 integrates two independent pipeline ADC cores with on-chip duty cycle stabilizer (DCS) and a configurable PLL that multiplies the input clock to generate the JESD204B data-rate clock. Its analog inputs accept 1.4–2.0 V_p-p differential signals with 2.5 pF input capacitance and 20 kΩ input resistance.

JESD204B serial output operates at up to 3.4 Gbps per lane (Subclass 0 or 1), with deterministic latency of 36 cycles in M2/L2 mode. The device supports integer 1-to-8 clock division, RFCLK input up to 1.5 GHz, and SYSREF± synchronization for multi-device timing alignment.

Key Specifications

Pinout & Package

AD9250BCPZRL7-170 is housed in a 48-lead, 7 mm × 7 mm LFCSP package with exposed thermal paddle soldered to ground plane. Pin count and layout are optimized for high-speed analog integrity and JESD204B signal routing.

Compared with AD9250BCPZRL7-250, the -170 variant reduces power by 104 mW while retaining identical interface, pinout, and feature set-ideal for thermally limited deployments. Versus AD9680BCPZRL7-500, it trades raw speed and SNR for lower cost, smaller footprint, and 57% less power-suited for established wireless standards rather than emerging wideband systems.

FAQ

What is the maximum analog input frequency supported by the AD9250BCPZRL7-170?

The AD9250BCPZRL7-170 supports analog input frequencies up to 400 MHz, defined by its 1000 MHz full-power bandwidth. This enables direct IF sampling of cellular, cable, and radar signals without downconversion. Performance metrics such as SNR and SFDR are specified up to 220 MHz, with usable dynamic range maintained across the full 400 MHz band under proper layout and filtering conditions. The AD9250BCPZRL7-170 achieves this using proprietary differential input architecture and on-chip DCS.

Does the AD9250BCPZRL7-170 require an external voltage reference?

No, the AD9250BCPZRL7-170 includes an internal analog-to-digital converter voltage reference, eliminating the need for an external reference IC. This integrated reference maintains a stable 1.75 V_p-p nominal input range across temperature and supply variations, simplifying system design and reducing BOM count. The reference can be overridden via SPI if an external precision reference is preferred, but default operation uses the internal source. This feature is confirmed in the AD9250BCPZRL7-170 datasheet Rev. E, Section "Voltage Reference".

What JESD204B subclass does the AD9250BCPZRL7-170 support?

The AD9250BCPZRL7-170 supports both JESD204B Subclass 0 and Subclass 1. Subclass 0 uses SYNCINB± for link initialization and provides simpler deterministic latency; Subclass 1 uses SYSREF± for multi-device synchronization and enables sample-aligned operation across multiple converters. Configuration is performed via SPI registers. The AD9250BCPZRL7-170's dual-subclass support allows deployment in both standalone and synchronized multi-ADC systems without hardware change.

How many JESD204B lanes does the AD9250BCPZRL7-170 use in default configuration?

In default configuration, the AD9250BCPZRL7-170 uses two JESD204B lanes (L = 2) with two converters (M = 2), delivering 170 MSPS per channel at 3.4 Gbps per lane. This M2/L2 setup ensures full throughput without data compression or lane multiplexing. Lane count and converter mapping are programmable via SPI, allowing reconfiguration to M1/L1 (single converter, one lane) for reduced FPGA resource usage at half the sampling rate.

What is the power-down current consumption of the AD9250BCPZRL7-170?

The AD9250BCPZRL7-170 consumes 9 mW in full power-down mode, as specified in Table 1 of the datasheet Rev. E. This ultra-low state disables all analog and digital circuitry-including ADC cores, serializers, and reference-while retaining register contents. Recovery time is 250 µs, enabling rapid wake-up for burst-mode operation. Standby mode draws 280–339 mW and maintains clock circuitry for faster resumption. These values are measured at 1.8 V supply and apply specifically to the AD9250BCPZRL7-170 speed grade.
