Product details
Overview
AD9467BCPZ-250 from Analog Devices is a 16-bit, 250 MSPS monolithic IF sampling analog-to-digital converter optimized for high dynamic range and wide bandwidth. 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 clock duty cycle stabilizer. It is used in cellular base station receivers requiring precise digitization of multiband IF signals.
For engineers reviewing the AD9467BCPZ-250 datasheet, AD9467BCPZ-250 pinout, AD9467BCPZ-250 application, or AD9467BCPZ-250 equivalent, key selection criteria include SFDR performance at 170–300 MHz, buffer current programmability for IF optimization, differential input compliance (2.0–2.5 V p-p), LVDS timing skew (±200 ps), and 72-lead LFCSP thermal management under industrial temperature conditions.
Technical Context
The AD9467BCPZ-250 implements a 16-bit pipelined architecture with 3-bit first stage, four 3-bit intermediate stages, and final 3-bit flash conversion, enabling continuous sampling at 250 MSPS on the rising clock edge. Its input buffer provides high impedance, low kick-back, and programmable current (80%/160%/210% per frequency band) to optimize SFDR across 0–300 MHz.
Digital interface includes SPI-configurable output format (offset binary/twos complement/Gray), serial port control, built-in test pattern generation, and LVDS-compatible DCO+/DCO− for synchronous data capture. Clock inputs accept CMOS/LVDS/LVPECL, with internal duty cycle stabilizer maintaining performance across variable input pulse widths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 16-bit - guarantees no missing codes and supports high-fidelity signal reconstruction in wideband IF sampling. |
| Sampling Rate | 250 MSPS - enables direct digitization of IF signals up to 125 MHz Nyquist zone without undersampling constraints. |
| SNR @ 210 MHz | 75.5 dBFS typical - defines usable dynamic range for high-frequency radar and communications waveforms. |
| SFDR @ 300 MHz | 90 dBFS typical - determines spurious-free resolution for multicarrier cellular receiver channel separation. |
| Aperture Jitter | 60 fs rms - limits sampling uncertainty-induced noise floor degradation above 100 MHz input frequencies. |
| Input Range | 2.0–2.5 V p-p differential - configurable full-scale span matching transformer-coupled or amplifier-driven front ends. |
| Power Supplies | 1.8 V (AVDD1/AVDD3/DRVDD) and 3.3 V (AVDD2) - dual-rail operation isolates analog core from digital output drivers. |
| Output Interface | LVDS (ANSI-644) - reduces EMI and supports >200 Mbps data rates over controlled-impedance PCB traces. |
Pinout & Package
The AD9467BCPZ-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. Thermal resistance θJA is 15.7°C/W (still air), and the EPAD must be soldered to AGND for optimal thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1–4, 7–15, 46, 52–63, 70–72 | AVDD1 | 1.8 V analog supply for core ADC pipeline stages; decoupling required per layout guidelines. |
| 5, 6 | CLK+, CLK− | Differential clock inputs accepting LVDS/LVPECL/CMOS; internal biasing eliminates external termination needs. |
| 66, 67 | VIN+, VIN− | Differential analog input pair with 530 Ω input resistance and 3.5 pF capacitance; requires matched source impedances. |
| 19–36 | D0+ to D15+, D0− to D15− | 16-bit LVDS data outputs; offset binary default; timing referenced to DCO+/DCO− for synchronous capture. |
| 27, 28 | DCO+, DCO− | Data clock output for latch alignment; propagation delay tCPD = 3 ns, skew ±200 ps relative to data. |
| 48–50 | SDIO, SCLK, CSB | 3-wire SPI interface for register configuration; supports read/write access to 128-location memory map. |
| 57 | XVREF | External reference input option; disables internal 1.25 V reference when driven with 1–1.25 V. |
| 0 | EPAD | Exposed thermal paddle; must be connected to AGND plane for thermal dissipation and ground integrity. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9467BCPZ-200 | Rated for 200 MSPS max; lower SFDR at >170 MHz (93 dBFS vs. 90 dBFS at 300 MHz); same pinout and SPI register map. | Preferred for cost-sensitive IF sampling below 150 MHz where 250 MSPS headroom is unnecessary. | Select AD9467BCPZ-200 only if system clock rate is ≤200 MSPS and SFDR >93 dBFS at target IF is sufficient. |
| ADS54J60IRGC | Texas Instruments 16-bit, 500 MSPS ADC; higher sampling rate but lower SNR (72.5 dBFS @ 210 MHz) and no integrated DCS. | Suitable for wider instantaneous bandwidth (>200 MHz) applications where clock jitter tolerance is managed externally. | Choose ADS54J60IRGC only when ≥500 MSPS sampling is mandatory and external clock conditioning is available. |
Compared with AD9467BCPZ-200 and ADS54J60IRGC, the AD9467BCPZ-250 uniquely balances 250 MSPS throughput, 90 dBFS SFDR at 300 MHz, and integrated clock stabilization-making it optimal for fixed-IF telecom infrastructure where jitter resilience and spurious suppression are critical.

FAQ
What is the maximum sampling rate supported by the AD9467BCPZ-250?
The AD9467BCPZ-250 is rated for a maximum sampling rate of 250 MSPS, as confirmed in Table 4 of the Rev. E datasheet. This rate is guaranteed across the full industrial temperature range (−40°C to +85°C) with AVDD1 = 1.8 V, AVDD2 = 3.3 V, and proper clock signal integrity. Operation beyond this rate is not characterized or supported.
Does the AD9467BCPZ-250 support external voltage reference?
Yes, the AD9467BCPZ-250 supports external reference via the XVREF pin (Pin 57). When an external 1.0–1.25 V reference is applied, the internal 1.25 V reference is disabled. This is documented in Table 1 and Pin Function Descriptions (Table 7), and enables precise gain calibration in metrology-grade systems.
How is SFDR optimized across different input frequencies for the AD9467BCPZ-250?
SFDR optimization for the AD9467BCPZ-250 is achieved by programming buffer current settings via SPI Registers 36 and 107: 80% (DC–150 MHz), 160% (150–250 MHz), and 210% (>250 MHz). These values are explicitly listed in the "AD9467BCPZ-250 buffer current settings" section of the datasheet Rev. E, page 19.
What package type and thermal characteristics does the AD9467BCPZ-250 use?
The AD9467BCPZ-250 uses a Pb-free, 72-lead LFCSP package with exposed paddle (EPAD), specified for −40°C to +85°C. Its thermal impedance is θJA = 15.7°C/W (still air), θJB = 7.5°C/W, and θJC = 0.5°C/W, per Table 6 in the Rev. E datasheet. The EPAD must be soldered to AGND for thermal and electrical integrity.
Can the AD9467BCPZ-250 operate with a single-ended analog input?
No-the AD9467BCPZ-250 analog input is strictly differential. The datasheet General Description and Analog Input Considerations sections state that SNR and SINAD degrade significantly with single-ended drive. Differential input (VIN+/VIN−) is required to achieve specified 75.5 dBFS SNR and 90 dBFS SFDR performance.
