Product details
Overview
AD9222BCPZ-40 from Analog Devices is an octal, 12-bit, 40 MSPS serial LVDS analog-to-digital converter with on-chip sample-and-hold, 1.8 V supply operation, 325 MHz full-power analog bandwidth, and 70 dB SNR at 2.4 MHz input. It serves as a high-density data acquisition front-end in ultrasound beamforming and optical networking systems.
For engineers reviewing the AD9222BCPZ-40 datasheet, AD9222BCPZ-40 pinout, AD9222BCPZ-40 application, or AD9222BCPZ-40 equivalent, this page delivers verified specs including resolution (12-bit), sampling rate (40 MSPS), power (740 mW total), LVDS output compliance (ANSI-644), and industrial temperature range (−40°C to +85°C).
Technical Context
The AD9222BCPZ-40 integrates eight independent ADC cores sharing a common 1.8 V AVDD/DRVDD supply and LVDS serial output interface. Each channel supports programmable clock/data alignment, flexible bit orientation (MSB/LSB first), and individual power-down mode consuming <2 mW when disabled.
Its serial LVDS interface operates at up to 390 MHz DCO frequency with DDR capability, delivering 12-bit data per channel via differential D+/D− pairs. The device includes built-in deterministic and pseudorandom digital test pattern generation accessible via SPI, plus frame clock (FCO) and data clock (DCO) outputs for synchronous capture.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12-bit - delivers 4096 discrete amplitude levels for precision digitization of wide dynamic range analog signals. |
| Sampling Rate | 40 MSPS - supports real-time digitization of baseband and IF signals up to 20 MHz Nyquist bandwidth. |
| SNR | 70.4 dB (typ, fIN = 2.4 MHz) - enables >11-bit effective resolution in low-noise signal chain applications. |
| ENOB | 11.38 bits (typ, fIN = 2.4 MHz) - quantifies actual usable resolution after noise and distortion are factored in. |
| Analog Bandwidth | 325 MHz - preserves signal integrity for wideband RF/IF inputs without external anti-alias filtering. |
| Supply Voltage | 1.8 V (AVDD and DRVDD) - reduces system power and simplifies power delivery versus higher-voltage ADCs. |
| Total Power | 740 mW (typ, 40 MSPS) - balances performance and thermal load in space-constrained multichannel systems. |
Pinout & Package
The AD9222BCPZ-40 is housed in a RoHS-compliant, 64-lead LFCSP (Lead Frame Chip Scale Package) with exposed paddle connected to AGND. Package dimensions: 9 mm × 9 mm × 0.85 mm.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AVDD (Pins 1,4,7,8,11,12,37,42,45,48,51,59,62) | Analog supply rail | 1.8 V power for all eight ADC cores; requires local decoupling to maintain SNR performance. |
| VIN+ A / VIN− A (Pins 43,44) | Differential analog input Channel A | Accepts 2 V p-p differential signal; common-mode voltage fixed at AVDD/2 (0.9 V). |
| D+ A / D− A (Pins 34,33) | LVDS serial data output Channel A | ANSI-644–compliant differential pair carrying 12-bit serialized data at up to 480 Mbps. |
| CLK+ / CLK− (Pins 10,9) | Differential sampling clock input | Accepts CMOS/LVDS/LVPECL clocks; minimum pulse width 12.5 ns at 40 MSPS. |
| DCO+ / DCO− (Pins 24,23) | Data clock output | DDR-capable clock synchronized to data edges; used by FPGA/ASIC for reliable LVDS capture. |
| FCO+ / FCO− (Pins 26,25) | Frame clock output | Indicates start of each new 12-bit output byte; aligns with MSB/LSB-first configuration. |
| PDWN (Pin 41) | Global power-down control | Active-high signal disabling all eight channels; reduces dissipation to <2 mW. |
| SCLK/DTP (Pin 38) | SPI clock / test pattern select | Controls serial port timing or selects internal digital test patterns (deterministic/pseudorandom). |
Key Features
| Feature | Design Value |
|---|---|
| Octal integration in single package | Reduces PCB area and interconnect complexity vs. eight discrete 12-bit ADCs; ideal for compact beamformers. |
| Programmable clock/data alignment | Compensates for board-level skew between clock and data paths-eliminates need for manual trace tuning. |
| Individual-channel power-down | Enables dynamic channel gating in time-sliced architectures (e.g., phased-array ultrasound), cutting idle power per channel. |
| Built-in digital test patterns | Supports production testing and system diagnostics without external pattern generators-reduces test setup cost. |
| Flexible output resolution | Allows runtime selection of 10-/12-bit modes via SPI, trading resolution for lower data throughput or power. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar octal ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9252BCPZ-40 | 14-bit resolution, same 64-lead LFCSP package, identical pinout and SPI interface. | Higher ENOB (12.4 bits) suits demanding radar or test equipment where dynamic range exceeds 12-bit needs. | Select AD9252BCPZ-40 when >11.3-bit ENOB is required; verify FPGA resource allocation for wider data bus. |

FAQ
What is the maximum analog input frequency supported by the AD9222BCPZ-40?
The AD9222BCPZ-40 features a 325 MHz full-power analog bandwidth, enabling accurate digitization of input signals up to that frequency without significant amplitude roll-off. This specification ensures faithful capture of wideband IF signals in radio receivers and ultrasound applications, provided the input drive meets the 2 V p-p differential requirement and common-mode voltage remains at AVDD/2 (0.9 V). Performance beyond 325 MHz is not guaranteed per datasheet specifications.
Does the AD9222BCPZ-40 require an external reference voltage?
No, the AD9222BCPZ-40 includes an internal 1.0 V reference and does not require an external reference for standard operation. The VREF pin can be used as an output (1.0 V ±30 mV) or as an input if an external reference is preferred. When using the internal reference, the SENSE pin must be tied to AVDD, and REFT/REFB pins are left unconnected. This simplifies system design and reduces BOM count compared to reference-dependent ADCs.
How many differential analog input channels does the AD9222BCPZ-40 provide?
The AD9222BCPZ-40 provides eight fully independent differential analog input channels (labeled A through H), each with dedicated VIN+ and VIN− pins. All channels share the same 1.8 V AVDD supply and clock domain but operate with matched gain, offset, and timing characteristics. This octal architecture enables simultaneous sampling across multiple sensors or antenna elements-critical for digital beamforming and parallel data acquisition systems.
What LVDS standard does the AD9222BCPZ-40 comply with for its serial outputs?
The AD9222BCPZ-40 serial LVDS outputs comply with ANSI TIA/EIA-644, the industry-standard LVDS electrical specification. Its default output mode delivers 247–454 mV differential voltage (VOD) with 1.125–1.375 V common-mode offset (VOS), meeting ANSI-644 thresholds for robust noise immunity and signal integrity. A low-power reduced-signal option (150–250 mV VOD) is also available via SPI configuration for systems prioritizing power over margin.
Can the AD9222BCPZ-40 operate with a 50 MSPS or 65 MSPS clock?
No-the AD9222BCPZ-40 is the 40 MSPS speed grade variant and is specified only up to 40 MSPS. While the AD9222 family includes -50 and -65 variants, the AD9222BCPZ-40's internal timing and AC specifications (e.g., SNR, SFDR, aperture jitter) are validated exclusively at ≤40 MSPS. Operating it beyond that rate violates datasheet limits and may result in missing codes, increased distortion, or functional failure. Use AD9222BCPZ-50 or AD9222BCPZ-65 for higher rates.
