Analog Devices Inc. AD9467BCPZ-200

Overview

AD9467BCPZ-200 from Analog Devices is a 16-bit, 200 MSPS analog-to-digital converter optimized for IF sampling in high-dynamic-range receivers. It delivers 75.5 dBFS SNR at 210 MHz input, 90 dBFS SFDR at 300 MHz, and 60 fs rms aperture jitter, with LVDS outputs and integrated input buffer - deployed in cellular base station receivers and radar signal chains.

For engineers reviewing the AD9467BCPZ-200 datasheet, AD9467BCPZ-200 pinout, AD9467BCPZ-200 application, or AD9467BCPZ-200 equivalent, key selection criteria include its 200 MSPS sampling rate, 2.5 V p-p differential full-scale input range, clock duty cycle stabilizer, serial port interface (SPI) configurability, and 72-lead LFCSP package thermal performance.

Technical Context

The AD9467BCPZ-200 implements a 16-bit pipelined ADC architecture with 3-bit first stage, four 3-bit intermediate stages, and final 3-bit flash conversion, enabling 200 MSPS sustained throughput with 16-clock-cycle pipeline latency. Its integrated input buffer provides high input impedance and reduces kick-back, while the clock duty cycle stabilizer maintains performance across variable input clock pulse widths.

Digital output uses ANSI-644–compliant LVDS signaling across 16 data pairs plus DCO± and OR±, powered by separate 1.8 V DRVDD and referenced to DRGND. Configuration and test pattern generation are managed via a standard SPI interface supporting offset binary, two's complement, or Gray coding formats.

FAQ

What is the maximum sampling rate supported by the AD9467BCPZ-200?

The AD9467BCPZ-200 supports a maximum sampling rate of 200 MSPS, as confirmed in Table 4 of the Rev. E datasheet. This is a fixed specification for this variant - unlike the AD9467BCPZ-250, which operates up to 250 MSPS. At 200 MSPS, the AD9467BCPZ-200 maintains full AC performance including 75.5 dBFS SNR at 210 MHz and 90 dBFS SFDR at 300 MHz under standard conditions.

Does the AD9467BCPZ-200 require an external reference voltage?

No, the AD9467BCPZ-200 includes an internal 1.25 V reference and operates fully with it enabled by default. An external reference can be applied via the XVREF pin if system-level accuracy or temperature stability requirements exceed the internal reference's ±0.5% initial tolerance and ±25 ppm/°C drift. The AD9467BCPZ-200 datasheet confirms internal reference functionality is active unless XVREF is externally driven above 1.0 V.

How is the input buffer current configured on the AD9467BCPZ-200?

The AD9467BCPZ-200 buffer current is configured via SPI-accessible registers 36 and 107. Per the datasheet's "SFDR Optimization-Buffer Current Adjustment" section, the default setting is 80% for DC–150 MHz; for 150–250 MHz inputs, it is set to 100%; and for >250 MHz, 160%. These settings optimize SFDR across frequency bands without altering pinout or power supply requirements of the AD9467BCPZ-200.

What package type and thermal characteristics does the AD9467BCPZ-200 use?

The AD9467BCPZ-200 uses a Pb-free, 72-lead LFCSP package with exposed thermal paddle (EPAD). Its thermal impedance is θJA = 15.7°C/W (still air), θJB = 7.5°C/W, and θJC = 0.5°C/W, as specified in Table 6. Successful thermal design requires soldering the EPAD to a solid AGND plane - a mandatory step to meet the −40°C to +85°C industrial temperature rating and prevent junction overheating at 1.26 W total dissipation.

Can the AD9467BCPZ-200 output data in Gray code format?

Yes, the AD9467BCPZ-200 supports Gray code output formatting via its SPI interface. Register 0x08 (Data Format Control) allows selection among offset binary (default), two's complement, and Gray code. This feature is explicitly documented in the "Serial Port Interface (SPI)" section and Memory Map table of the Rev. E datasheet, enabling glitch-free MSB transitions during high-speed data capture in FPGA-based systems.
