Product details
Overview
AD9239BCPZ-170 from Analog Devices is a quad-channel, 12-bit, 170 MSPS analog-to-digital converter with serial CML outputs, on-chip temperature sensor, and −95 dB channel-to-channel crosstalk. It operates from a single 1.8 V supply, supports 1.25 V p-p differential input range, and delivers 64.5 dB SNR at 9.7 MHz input - used in broadband radio receivers and cable head-end digitization.
For engineers reviewing the AD9239BCPZ-170 datasheet, AD9239BCPZ-170 pinout, AD9239BCPZ-170 application, or AD9239BCPZ-170 equivalent, key selection criteria include sampling rate (170 MSPS), serial CML output compliance, deterministic jitter (10 ps max), channel isolation (−95 dB), and industrial temperature range (−40°C to +85°C).
Technical Context
The AD9239BCPZ-170 implements a pipelined switched-capacitor ADC architecture with digital correction logic, sampling on the rising clock edge and delivering 12-bit results via serialized packetized output containing channel-specific data, scrambled samples, and 8-bit ECC per channel. Its on-chip PLL distributes and multiplies the input clock to generate internal high-speed data-rate clocks.
It features a clock duty cycle stabilizer (DCS) enabling full-performance operation across wide input clock duty cycles, and supports flexible analog input coupling (differential transformer, balun, or active amplifier). The serial interface uses current-mode logic (CML) drivers with 100 Ω differential termination and deterministic jitter ≤10 ps.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Resolution | 12 bits - provides 4096 quantization levels with guaranteed no missing codes over temperature. |
| SNR @ 9.7 MHz | 64.5 dBFS - enables >10.4 ENOB for baseband signal fidelity in communication receivers. |
| Full-Power Bandwidth | 780 MHz - supports direct RF sampling of IF signals up to second Nyquist zone without external filtering. |
| Channel Crosstalk | −95 dB - ensures minimal inter-channel interference in multi-channel MIMO or phased-array systems. |
| Power Dissipation | 1.139 W total - includes 535 mA AVDD and 98 mA DRVDD at 170 MSPS, enabling thermal management in dense PCB layouts. |
| Deterministic Jitter | 10 ps max - guarantees timing predictability for synchronous serial capture in FPGA-based receivers. |
Pinout & Package
The AD9239BCPZ-170 is housed in a Pb-free/RoHS-compliant 72-lead LFCSP package (CP-72-3) with exposed paddle soldered to ground plane for thermal and EMI performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| CLK+, CLK− | Differential clock input | Accepts LVPECL/LVDS/CMOS; internal 1.2 V common-mode bias eliminates external termination resistors. |
| VIN+ A/D, VIN− A/D | Differential analog inputs (per channel) | Four independent pairs support simultaneous sampling; require matched source impedance for <−95 dB crosstalk. |
| DOUT+ A/D, DOUT− A/D | Serialized CML digital outputs | 12-bit data per channel at 2.72 Gbps NRZ; require 100 Ω differential termination at receiver. |
| AVDD, DRVDD | 1.8 V analog/digital supplies | Separate power domains isolate noise-sensitive analog core from high-speed serial output drivers. |
| TEMPOUT | Analog temperature sensor output | −1.12 mV/°C slope with 739 mV offset at 25°C - enables system-level thermal monitoring without external sensors. |
| PDWN, RESET | Power-down and timing reset control | Asynchronous PDWN reduces dissipation to 3 mW; RESET synchronizes pipeline latency (40 CLK cycles) across all four channels. |
Key Features
| Feature | Design Value |
|---|---|
| Coded serial output with ECC | 8-bit error correction code per 64-bit packet prevents bit errors in noisy backplane or flex-cable environments. |
| On-chip temperature sensor | Monitors die temperature with ±1°C accuracy over −40°C to +85°C - enables dynamic gain calibration in radar subsystems. |
| Programmable pin functions (PGM0–PGM3) | Four user-configurable pins support hardware-defined operating modes without SPI reconfiguration during runtime. |
| Adjustable input voltage range | 1.0–1.5 V p-p differential span configurable via SPI Register 18 - optimizes dynamic range for varying signal chain gain. |
| Serial port interface (SPI) | 4-wire (CSB/SCLK/SDI/SDO) or 3-wire (SDIO) configuration enables register access while maintaining low pin count. |
Applications
| Communication Receivers | Cable Head-End Equipment |

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 |
|---|---|---|---|
| AD9239BCPZ-210 | Higher sampling rate (210 MSPS), higher power (1.386 W), same pinout/package | Supports wider Nyquist bandwidth (105 MHz) but requires tighter clock jitter budget (<8 ps rms) | Select when system demands >85 MHz instantaneous bandwidth and can accommodate increased thermal load. |
| AD9680BCPZ-170 | 14-bit resolution, dual-channel only, JESD204B interface instead of CML, 1.25 V p-p input range | Targets higher dynamic range applications (e.g., medical ultrasound) with lower channel count and serial protocol overhead | Choose when ENOB > 11 bits is required and FPGA JESD204B IP is available; not drop-in compatible due to interface and channel count mismatch. |
Compared with AD9239BCPZ-210 and AD9680BCPZ-170, the AD9239BCPZ-170 offers optimal balance of channel density, power efficiency (1.139 W), and legacy CML interface simplicity for cost-sensitive broadband infrastructure designs where 12-bit resolution suffices.

FAQ
What is the maximum analog input frequency supported by the AD9239BCPZ-170?
The AD9239BCPZ-170 has a full-power analog bandwidth of 780 MHz, enabling direct sampling of IF signals up to the second Nyquist zone. At 170 MSPS sampling rate, its usable Nyquist bandwidth is 85 MHz for real signals, but aliasing allows digitization of higher-frequency bandpass signals centered at multiples of fS/2, provided input filtering and layout preserve signal integrity.
Does the AD9239BCPZ-170 support single-ended analog input configurations?
The AD9239BCPZ-170 is optimized for differential analog input operation. While a single-ended configuration is possible (e.g., driving VIN+ A with 1.25 V p-p and terminating VIN− A), it degrades SFDR and distortion performance due to common-mode swing mismatch. Differential drive using transformers or amplifiers like ADA4937 is required to achieve specified −95 dB crosstalk and 64.5 dB SNR.
How does the clock duty cycle stabilizer (DCS) function in the AD9239BCPZ-170?
The AD9239BCPZ-170's DCS retimes the nonsampling clock edge to produce an internal 50% duty cycle signal, allowing full dynamic performance across input clock duty cycles from 30% to 70%. It remains active by default (Register 9 bit 0 = 1) and is recommended for all applications except those requiring sub-50 MHz clock rates, where DCS is disabled automatically.
What is the purpose of the TEMPOUT pin on the AD9239BCPZ-170?
The TEMPOUT pin on the AD9239BCPZ-170 provides an analog voltage output proportional to die temperature (−1.12 mV/°C slope, 739 mV at 25°C), enabling real-time thermal monitoring without external sensors. This output drives a 50 µA load and is used for system-level calibration, thermal throttling, or drift compensation in radar and test equipment applications.
Can the AD9239BCPZ-170 be powered down to reduce system power consumption?
Yes, the AD9239BCPZ-170 supports hardware-controlled power-down via the PDWN pin, reducing total dissipation to 3 mW. In standby mode (enabled via SPI), it consumes 152 mW while maintaining digital link functionality - ideal for burst-mode receivers or time-division multiplexed systems requiring rapid wake-up (250 ns).
