Product details
Overview
AD9253BCPZ-80 from Analog Devices is a quad-channel, 14-bit, 80 MSPS serial LVDS analog-to-digital converter operating from a single 1.8 V supply. It delivers 74 dB SNR and 90 dBc SFDR at Nyquist, supports 650 MHz full-power analog bandwidth, and features built-in digital test pattern generation for high-speed imaging and medical ultrasound systems.
For engineers reviewing the AD9253BCPZ-80 datasheet, AD9253BCPZ-80 pinout, AD9253BCPZ-80 application, or AD9253BCPZ-80 equivalent, this page provides verified specifications, validated pin functions, confirmed industrial-temperature operation (−40°C to +85°C), RoHS-compliant 48-lead LFCSP packaging, and real-world timing and power behavior at its rated 80 MSPS conversion rate.
Technical Context
The AD9253BCPZ-80 implements a multistage pipelined ADC architecture with 1-bit redundancy per stage for digital error correction, sampling on the rising edge of the clock. Its serializer outputs 16-bit data in DDR LVDS format across two lanes, synchronized by dedicated DCO and FCO signals.
It integrates a 1.0 V internal reference, programmable output resolution (12-/16-bit), flexible bit orientation, and multichip sync capability via the SYNC input. Power management includes per-channel power-down (<2 mW total off-state) and standby mode (178 mW), all controlled through a 3-wire SPI interface.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 14-bit - guarantees no missing codes over full industrial temperature range |
| Sample Rate | 80 MSPS - maximum sustained conversion rate with full AC performance (SNR = 74 dBFS, SFDR = 90 dBc) |
| Analog Bandwidth | 650 MHz - enables direct RF sampling up to IF frequencies without external amplification |
| Supply Voltage | 1.8 V AVDD/DRVDD - single-rail operation reduces system power delivery complexity |
| Input Range | 2 V p-p differential - maximizes dynamic range and SNR when driven with matched transformer or amplifier |
| Power Consumption | 349 mW (sine input, four channels, ANSI-644 LVDS) - scalable to reduced-signal LVDS mode for lower EMI |
| Aperture Jitter | 135 fs rms - ensures <12.2 ENOB at 9.7 MHz input, critical for time-domain fidelity |
Pinout & Package
AD9253BCPZ-80 is housed in a RoHS-compliant, thermally enhanced 48-lead LFCSP (7 mm × 7 mm, CP-48-13) with exposed analog ground pad requiring PCB soldering for thermal and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| AGND (Exposed Pad) | Analog Ground Reference | Mandatory connection to system AGND plane; provides primary thermal path and low-impedance return for analog circuitry |
| 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 routing and common-mode bias at VCM = 0.9 V |
| CLK+, CLK− | Differential Clock Input | Accepts LVDS/LVPECL/CMOS; 10–1000 MHz range; determines sample rate after internal divider configuration |
| D0±A–D1±D, DCO±, FCO± | LVDS Digital Outputs | Two-lane serial LVDS interface: D0/D1 per channel, DCO for DDR data capture, FCO for byte framing; ANSI-644 compliant |
| SCLK, SDIO, CSB | SPI Serial Interface | 3-wire interface (SCLK/SDIO/CSB) for register configuration, test pattern control, and power mode selection |
| PDWN, SYNC | Control Inputs | PDWN high forces full chip power-down; SYNC synchronizes multichip clock dividers for deterministic latency alignment |
Key Features
| Feature | Design Value |
|---|---|
| Quad-channel integration | Four independent 14-bit ADCs in one 7 mm × 7 mm LFCSP - reduces board area and inter-channel skew vs. discrete solutions |
| Programmable output resolution | Configurable 12-bit or 16-bit output via SPI - enables trade-off between data throughput and precision without hardware change |
| Built-in digital test patterns | Deterministic, pseudorandom, and custom user-defined patterns - eliminates need for external signal generators during production test |
| Flexible clock/data alignment | Adjustable DCO-to-data delay and FCO phase via register settings - simplifies FPGA capture timing closure across PVT corners |
| Scalable LVDS output modes | ANSI-644 (345 mV VOD) or low-power reduced-signal (200 mV VOD) - allows optimization for signal integrity or EMI compliance |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-channel, 14-bit, 80 MSPS ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9253BCPZ-105 | Higher max sample rate (105 MSPS); higher power (405 mW typical); identical pinout and SPI register map | Required for systems needing >80 MSPS bandwidth or improved SFDR at fIN > 70 MHz | Select AD9253BCPZ-105 only if design requires headroom beyond 80 MSPS or tighter SFDR specs above 70 MHz input |
| AD9633BCPZ-80 | 12-bit resolution; pin-compatible; lower power (240 mW); lower SFDR (82 dBc); no built-in test patterns | Suitable for cost-sensitive applications where 12-bit ENOB suffices and external test equipment is available | Choose AD9633BCPZ-80 for legacy designs migrating from AD9253 or where resolution budget permits 12-bit trade-off for power/space savings |
Compared with AD9253BCPZ-105, the AD9253BCPZ-80 offers lower power and guaranteed 80 MSPS performance with identical layout compatibility; versus AD9633BCPZ-80, it delivers +2 bits resolution, +8 dB SFDR, and integrated test capability-justifying its use in high-fidelity signal capture where quantization noise and spurious content must be minimized.

FAQ
What is the maximum analog input frequency supported by the AD9253BCPZ-80?
The AD9253BCPZ-80 features a 650 MHz full-power analog bandwidth, enabling accurate digitization of input signals up to 200 MHz while maintaining 70.7 dB SNR and 84 dBc SFDR. This bandwidth is measured under standard conditions (2 V p-p differential input, −1.0 dBFS, 25°C) and supports direct RF sampling in IF-staging architectures without external amplification.
Does the AD9253BCPZ-80 require an external voltage reference?
No, the AD9253BCPZ-80 includes an internal 1.0 V reference with ±2% tolerance over temperature (0.98 V to 1.02 V). It can operate in buffered reference mode (VREF pin used as output) or accept an external reference (0.5 V to 1.25 V) via the same pin. External reference is optional and only needed when higher absolute accuracy or temperature stability is required beyond the internal reference's specification.
How does the AD9253BCPZ-80 handle multichip synchronization?
The AD9253BCPZ-80 uses the SYNC input to align internal clock dividers across multiple devices. When asserted synchronously with the master clock, SYNC resets the divider phase, ensuring deterministic pipeline latency and frame alignment across all AD9253BCPZ-80 units. This enables coherent sampling in phased-array or MIMO systems without FPGA-level deskew logic.
What LVDS output standards does the AD9253BCPZ-80 support?
The AD9253BCPZ-80 supports two LVDS output modes: default ANSI-644 compliance (345 mV typical differential output voltage) and a low-power reduced-signal option (200 mV typical VOD), both with 1.25 V common-mode. Mode selection is configurable via SPI register 0x14, allowing trade-offs between signal integrity margin and EMI reduction based on PCB stackup and cable length.
Can the AD9253BCPZ-80 operate with a single 1.8 V supply only?
Yes, the AD9253BCPZ-80 operates from a single 1.8 V supply applied to both AVDD (analog core) and DRVDD (digital output drivers). The datasheet specifies AVDD = DRVDD = 1.8 V ±0.1 V across the industrial temperature range. No separate analog/digital rail separation is required, simplifying power delivery design while maintaining specified SNR and SFDR performance.
