Analog Devices Inc. AD9467BCPZRL7-250

Overview

AD9467BCPZRL7-250 from Analog Devices is a 16-bit, 250 MSPS IF sampling analog-to-digital converter optimized for high dynamic range in wideband receiver systems. It delivers 75.5 dBFS SNR at 210 MHz input and 90 dBFS SFDR at 300 MHz, with 60 fs rms aperture jitter, integrated input buffer, and LVDS outputs - deployed in cellular base station receivers and radar instrumentation.

For engineers reviewing the AD9467BCPZRL7-250 datasheet, AD9467BCPZRL7-250 pinout, AD9467BCPZRL7-250 application, or AD9467BCPZRL7-250 equivalent, key selection criteria include SFDR performance at 170–300 MHz IFs, differential input voltage range programmability (2–2.5 V p-p), clock duty cycle stabilization, serial port configurability, and thermal performance in LFCSP packaging.

Technical Context

The AD9467BCPZRL7-250 implements a 16-bit pipelined architecture with 3-bit first stage, four 3-bit intermediate stages, and final 3-bit flash conversion, enabling 250 MSPS sustained sampling on the rising clock edge. Its input buffer provides high impedance, low kick-back, and adjustable current (80–210% via SPI registers) to optimize SFDR across 0–300 MHz analog bandwidth.

Digital output uses ANSI-644–compliant LVDS with DCO± for synchronous data capture, while internal clock duty cycle stabilizer (DCS) maintains performance across variable input clock pulse widths. Serial port interface supports offset binary, two's complement, or Gray coding, and built-in test pattern generation aids system validation.

Key Specifications

Pinout & Package

The AD9467BCPZRL7-250 is housed in a Pb-free, 72-lead LFCSP (Lead Frame Chip Scale Package) with exposed paddle, specified for −40°C to +85°C operation. The EPAD must be soldered to AGND for thermal and electrical integrity.

FAQ

What is the maximum sampling rate supported by the AD9467BCPZRL7-250?

The AD9467BCPZRL7-250 is rated for a maximum sustained sampling rate of 250 MSPS. This rate is fully characterized across AC specifications including SNR, SFDR, and ENOB at input frequencies up to 300 MHz. Performance remains guaranteed under specified supply voltages (1.8 V and 3.3 V), temperature range (−40°C to +85°C), and default SPI settings. Exceeding 250 MSPS is not supported and may result in undefined behavior or specification violation.

Does the AD9467BCPZRL7-250 require an external reference voltage?

No, the AD9467BCPZRL7-250 includes an internal 1.25 V reference and operates fully with it enabled by default. The XVREF pin supports optional external reference (1–1.25 V) for applications demanding tighter reference stability or customized full-scale range, but external reference is not required. When XVREF is left unconnected, the internal reference remains active and functional.

How does the clock duty cycle stabilizer (DCS) function in the AD9467BCPZRL7-250?

The clock duty cycle stabilizer (DCS) in the AD9467BCPZRL7-250 actively corrects input clock duty cycle deviations to maintain optimal ADC linearity and SFDR performance. It accepts LVDS, LVPECL, or CMOS clock inputs with pulse widths ranging from 2 ns high/low (at 250 MSPS) and compensates for asymmetry without requiring external clock conditioning circuitry. DCS is enabled by default and contributes directly to the specified 60 fs rms aperture jitter.

What output data formats does the AD9467BCPZRL7-250 support?

Through its serial port interface (SPI), the AD9467BCPZRL7-250 supports three output data formats: offset binary (default), two's complement, and Gray code. Format selection is performed via register configuration and applies to all 16 data outputs (D0–D15). Each format is fully compatible with the LVDS output drivers and DCO timing, allowing seamless integration with diverse FPGA or ASIC data capture logic.

Is the AD9467BCPZRL7-250 pin-compatible with other members of the AD9467 family?

Yes, the AD9467BCPZRL7-250 shares identical pinout, package (72-lead LFCSP), and footprint with AD9467BCPZ-200, AD9467BCPZ-250, and AD9467BCPZRL7-200. All variants use the same register map, SPI interface, and functional pin assignments. The only differences are maximum sampling rate rating and associated AC performance curves - making them mechanically and electrically interchangeable on PCBs designed for the AD9467 family.
