Product details
Overview
AD9467SCPZ-250-EP from Analog Devices is a 16-bit, 250 MSPS monolithic IF sampling analog-to-digital converter optimized for high dynamic range in wideband RF/IF receiver chains. It delivers 75.5 dBFS SNR at 210 MHz input, 90 dBFS SFDR at 300 MHz, and 60 fs rms aperture jitter, enabling precision digitization in radar, multicarrier cellular base stations, and infrared imaging systems.
For engineers reviewing the AD9467SCPZ-250-EP datasheet, AD9467SCPZ-250-EP pinout, AD9467SCPZ-250-EP application, or AD9467SCPZ-250-EP equivalent, key selection criteria include its extended temperature operation (−55°C to +125°C), LVDS output compliance (ANSI-644), integrated clock duty cycle stabilizer, and programmable 2.0–2.5 Vp-p differential input range with on-chip buffer and reference.
Technical Context
The AD9467SCPZ-250-EP employs a pipeline ADC architecture with internal 1.25 V reference and fully differential input stage, supporting up to 900 MHz full-power bandwidth. Its clock duty cycle stabilizer (DCS) maintains performance across variable input clock pulse widths, while the serial port interface (SPI) enables runtime configuration of data format, test patterns, and input range.
It features 16-bit LVDS outputs (D0± to D15±), a dedicated data clock output (DCO±) with ±200 ps skew tolerance, and out-of-range indicators (OR±). Power delivery is segmented across AVDD1 (1.8 V), AVDD2 (3.3 V), AVDD3 (1.8 V), and DRVDD (1.8 V), with total dissipation of 1.5 W at full rate and <90 mW in power-down mode.
Key Specifications

Pinout & Package
The AD9467SCPZ-250-EP is housed in a Pb-free, 72-lead LFCSP (10 mm × 10 mm, 0.85 mm height, CP-72-5) with exposed thermal pad requiring connection to AGND for thermal and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN+, VIN− | Analog input differential pair | Accepts 2.0–2.5 Vp-p differential signal; high input impedance (530 Ω) and low capacitance (3.5 pF) minimize loading on preceding filter or transformer. |
| CLK+, CLK− | Differential clock input | Supports CMOS/LVDS/LVPECL logic; internal DCS corrects duty cycle to maintain timing margin at 250 MSPS. |
| D0+ to D15+, D0− to D15− | 16-bit LVDS data outputs | ANSI-644-compliant; 247–545 mV differential swing enables reliable capture by FPGA or ASIC receivers. |
| DCO+, DCO− | Data clock output | Provides synchronous edge-aligned clock for latch timing; ±200 ps skew tolerance simplifies high-speed capture design. |
| OR+, OR− | Out-of-range indicator | LVDS signal flags when input exceeds full-scale range-critical for automatic gain control and clipping detection. |
| CSB, SCLK, SDIO | SPI interface | Configures data format (offset binary/twos complement/Gray), test patterns, and power modes without external logic. |
| XVREF | External reference input | Accepts 1.0–1.25 V external reference for improved system-level accuracy or temperature stability. |
| AVDD1/AVDD2/AVDD3/DRVDD | Supply rails | Segmented 1.8 V and 3.3 V supplies isolate analog core, I/O drivers, and digital logic to suppress supply-induced noise coupling. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated input buffer | Eliminates need for external driver amplifiers in many IF sampling applications, reducing BOM count and layout complexity. |
| On-chip 1.25 V reference | Enables standalone operation without external voltage reference; optional XVREF pin supports higher-precision external references. |
| Programmable input range | 2.0–2.5 Vp-p differential full-scale setting allows trade-off between noise floor and overload margin per system requirement. |
| Built-in test pattern generation | Serially selectable digital patterns (e.g., ramp, checkerboard) simplify board-level validation and production testing. |
| Power-down mode via SPI | Reduces dissipation to <90 mW, enabling rapid power cycling in time-sliced or burst-mode receiver architectures. |

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-250 | Commercial temperature grade (−40°C to +85°C); identical AC/DC specs and pinout. | Not qualified for aerospace, defense, or extended-temperature industrial use. | Select AD9467BCPZ-250 only if operating environment remains within commercial range and cost sensitivity outweighs reliability assurance. |
| ADS54J60IRGC | Texas Instruments 16-bit, 500 MSPS ADC; higher sample rate but lower SFDR (87 dBFS at 200 MHz) and no extended temp option. | Targets higher-bandwidth applications where SNR/SFDR trade-offs are acceptable for throughput gain. | Choose ADS54J60IRGC when system requires >250 MSPS sampling and can accommodate reduced spurious performance and narrower temperature range. |
Compared with AD9467BCPZ-250, the AD9467SCPZ-250-EP adds military-grade qualification and extended temperature support without sacrificing linearity or noise performance; versus ADS54J60IRGC, it trades raw speed for superior SFDR and guaranteed operation in extreme environments-making it optimal for mission-critical IF sampling where fidelity and reliability are non-negotiable.

FAQ
What is the maximum analog input frequency supported by the AD9467SCPZ-250-EP?
The AD9467SCPZ-250-EP has a full-power bandwidth of 900 MHz, meaning it can accurately digitize analog inputs up to that frequency while maintaining specified SNR and SFDR performance. At 250 MSPS sampling, the Nyquist frequency is 125 MHz, but the device's wide analog bandwidth supports undersampling of IF signals well beyond Nyquist-enabling direct digitization of 210 MHz inputs with 75.5 dBFS SNR as verified in the datasheet.
Does the AD9467SCPZ-250-EP require an external reference voltage?
No-the AD9467SCPZ-250-EP includes an internal 1.25 V reference and operates fully stand-alone with default settings. However, the XVREF pin allows connection of an external reference (1.0–1.25 V) for improved accuracy, temperature drift, or system-level calibration traceability-making AD9467SCPZ-250-EP flexible for both cost-sensitive and metrology-grade designs.
How does the clock duty cycle stabilizer (DCS) function in the AD9467SCPZ-250-EP?
The AD9467SCPZ-250-EP's internal clock duty cycle stabilizer automatically corrects input clock asymmetry, ensuring consistent setup/hold timing margins even with LVDS or LVPECL clocks exhibiting 40%–60% duty cycles. This eliminates the need for external duty-cycle correction circuitry and maintains full 250 MSPS performance across process, voltage, and temperature variations-critical for stable operation in field-deployed systems.
What LVDS output standards does the AD9467SCPZ-250-EP comply with?
The AD9467SCPZ-250-EP LVDS outputs meet ANSI TIA/EIA-644-A specifications, delivering 247–545 mV differential voltage swing and 1.125–1.375 V common-mode offset. These outputs drive standard FPGA or ASIC LVDS receivers directly, supporting trace lengths up to ~15 cm on FR-4 PCBs without termination resistors-reducing layout complexity and power consumption compared to parallel CMOS interfaces.
Is the AD9467SCPZ-250-EP pin-compatible with other members of the AD9467 family?
Yes-the AD9467SCPZ-250-EP shares identical pinout, package (72-lead LFCSP), and footprint with AD9467BCPZ-250 and AD9467BCPZ-250RL7. All variants use the same functional block diagram, register map, and SPI command set, allowing drop-in replacement in existing designs when extended temperature or enhanced product qualification is required.
