Product details
Overview
AD9633BCPZ-125 from Analog Devices is a quad-channel, 12-bit, 125 MSPS analog-to-digital converter with serial LVDS output, 1.8 V supply operation, 71 dB SNR (to Nyquist), 91 dBc SFDR (to Nyquist), and 650 MHz full-power analog bandwidth. It integrates on-chip sample-and-hold, programmable output clock/data alignment, multichip sync, and individual-channel power-down for medical ultrasound and high-speed imaging systems.
For engineers reviewing the AD9633BCPZ-125 datasheet, AD9633BCPZ-125 pinout, AD9633BCPZ-125 application, or AD9633BCPZ-125 equivalent, this page delivers verified specifications, validated pin functions, confirmed industrial-temperature operation (−40°C to +85°C), RoHS-compliant 48-lead LFCSP packaging, and real-world ADC selection criteria including SNR/SFDR trade-offs, LVDS lane configuration options, and SPI-controlled digital test pattern generation.
Technical Context
The AD9633BCPZ-125 implements a multistage pipelined architecture with 1-bit redundancy per stage for digital error correction and 16-clock-cycle pipeline latency. It supports dual-lane LVDS output with DDR timing, frame clock (FCO) and data clock (DCO) outputs synchronized to sample rate, and programmable resolution (10/12-bit) and bit orientation.
Its analog input uses a differential switched-capacitor front-end with 2 V p-p full-scale range and externally set common-mode voltage (VCM = AVDD/2 recommended). Clock inputs accept LVDS/LVPECL/CMOS, and internal reference is fixed at 1.0 V with ±2% tolerance over temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 12-bit - Delivers 12-bit quantization depth with guaranteed no missing codes across industrial temperature range. |
| Sampling Rate | 125 MSPS - Maximum conversion rate enabling digitization of IF signals up to 200 MHz with usable SNR. |
| SNR (to Nyquist) | 71 dB - Enables >11.5 ENOB at 9.7 MHz input, critical for dynamic range in medical ultrasound beamforming. |
| SFDR (to Nyquist) | 91 dBc - Suppresses spurious content sufficiently for quadrature radio receiver applications with adjacent-channel rejection. |
| Analog Bandwidth | 650 MHz - Supports wideband RF/IF sampling without external anti-alias filtering below 325 MHz. |
| Power per Channel | 100 mW at 125 MSPS - Enables four-channel digitization in space-constrained systems with thermal budget under 400 mW total. |
| Differential Nonlinearity | ±0.3 LSB (typ) - Ensures monotonicity and low harmonic distortion in precision imaging signal chains. |
| Supply Voltage | 1.8 V (AVDD/DRVDD) - Reduces system-level power delivery complexity and enables direct interface with 1.8 V FPGA I/O banks. |
Pinout & Package
AD9633BCPZ-125 is housed in a RoHS-compliant, thermally enhanced 48-lead LFCSP (7 mm × 7 mm, CP-48-13), with exposed analog ground pad requiring solder connection to PCB ground plane for optimal thermal and noise performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AGND (Exposed Pad) | Analog Ground Reference | Primary thermal path and analog reference node; must be solidly connected to PCB ground plane for <7.1°C/W θJC. |
| VIN+A / VIN−A to VIN+C / VIN−C | Differential Analog Inputs (Ch A–C) | Four independent 2 V p-p differential input pairs; each pair requires matched trace length and controlled impedance (100 Ω). |
| CLK+/CLK− | Differential Sample Clock Input | Accepts LVDS/LVPECL/CMOS; determines conversion rate and directly controls aperture jitter (135 fs rms). |
| D0±A–D1±D, DCO±, FCO± | LVDS Digital Outputs | Two-lane serial LVDS outputs per channel (default); DCO aligns with DDR data edges; FCO marks byte boundaries. |
| SCLK/SDIO/CSB | SPI Serial Interface | 3-wire SPI (SCLK, SDIO bidirectional, CSB active-low) configures output mode, test patterns, power states, and clock dividers. |
| PDWN / SYNC | Control Logic Inputs | PDWN high forces full chip power-down (<2 mW); SYNC enables multichip synchronization of clock dividers across multiple AD9633 devices. |
Key Features
| Feature | Design Value |
|---|---|
| Programmable Output Resolution | Supports 10-bit or 12-bit LVDS output via SPI register 0x14, reducing FPGA resource usage when full resolution is unnecessary. |
| Individual Channel Power-Down | Each ADC channel can be disabled independently via SPI, reducing power by ~100 mW per channel while preserving others' operation. |
| Built-in Digital Test Patterns | Includes deterministic, pseudorandom, and custom user-defined patterns accessible via SPI-enables production testing without external signal sources. |
| Flexible LVDS Output Modes | Configurable two-lane (default) or one-lane serial output; supports DDR/SDR and 1×/2× frame modes to match FPGA capture capability. |
| Serial Port Control (SPI) | Full register access for clock divider ratio, output alignment, gain/offset calibration, and digital gain control-eliminates need for external configuration logic. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-channel, 12-bit, high-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9253BCPZ-125 | 14-bit resolution, same 48-lead LFCSP package and pinout; higher power (145 mW/channel), lower max sample rate (125 MSPS same, but AC specs optimized for lower frequencies). | Better DC precision and SNR at lower input frequencies (<50 MHz); less suitable for wideband IF sampling above 100 MHz due to reduced SFDR at high fIN. | Select AD9253BCPZ-125 when 14-bit resolution and superior INL (±0.3 LSB) outweigh bandwidth and power requirements. |
| ADS4149IRGZT | Quad 14-bit, 250 MSPS; JESD204B output instead of LVDS; 64-pin VQFN; higher power (180 mW/channel); no integrated reference. | Targets higher-speed systems requiring JESD204B lane consolidation and FPGA SerDes integration; lacks built-in test patterns and multichip sync. | Select ADS4149IRGZT when migrating to JESD204B-based architectures and needing >125 MSPS throughput with deterministic latency. |
Compared with AD9253BCPZ-125 and ADS4149IRGZT, AD9633BCPZ-125 uniquely balances 125 MSPS speed, LVDS simplicity, integrated reference, and multichip sync in a compact LFCSP-making it optimal for cost-sensitive, space-constrained, wideband digitization where 12-bit resolution suffices.

FAQ
What is the maximum analog input frequency supported by the AD9633BCPZ-125?
The AD9633BCPZ-125 has a full-power analog bandwidth of 650 MHz, meaning it maintains specified SNR and SFDR performance for input signals up to 650 MHz. At 200 MHz input frequency, SNR remains 69.4 dBFS and SFDR is 86 dBc, confirming usability well into UHF bands. Performance degrades gradually beyond this point due to front-end roll-off, not hard cutoff.
Does the AD9633BCPZ-125 require an external voltage reference?
No, the AD9633BCPZ-125 includes an internal 1.0 V reference with ±2% tolerance over temperature, eliminating the need for external reference components in most applications. The VREF pin serves as both input and output; if an external reference is used, it must be 1.0 V and drive the internal reference buffer.
How does the AD9633BCPZ-125 handle multichip synchronization?
The AD9633BCPZ-125 supports multichip sync via its SYNC input pin and internal clock divider. When SYNC pulses are applied synchronously across multiple AD9633BCPZ-125 devices, their internal dividers reset simultaneously, ensuring deterministic phase alignment of sample clocks and serialized data streams-critical for coherent array processing.
What LVDS output modes does the AD9633BCPZ-125 support?
The AD9633BCPZ-125 supports two LVDS output configurations: default two-lane mode (D0±x/D1±x per channel) and configurable one-lane mode (via SPI register 0x21 Bits[6:4]). Both support DDR or SDR timing and 1× or 2× frame modes, allowing optimization for FPGA I/O count, timing margin, and PCB layer count.
Can the AD9633BCPZ-125 operate with a single 1.8 V supply?
Yes, the AD9633BCPZ-125 operates from a single 1.8 V supply for both analog (AVDD) and digital driver (DRVDD) domains. AVDD and DRVDD pins are internally isolated but share the same 1.8 V rail, simplifying power delivery. Total power consumption is 430 mW typical at 125 MSPS with sine-wave input and ANSI-644 LVDS output.
