Product details
Overview
AD9642BCPZ-170 from Analog Devices is a 14-bit, 170 MSPS analog-to-digital converter (ADC) with LVDS parallel DDR outputs, 1.8 V single-supply operation, and integrated voltage reference. It delivers 71.2 dBFS SNR at 185 MHz input and 86 dBc SFDR, targeting high-performance communications receivers requiring wide bandwidth and low power.
For engineers reviewing the AD9642BCPZ-170 datasheet, AD9642BCPZ-170 pinout, AD9642BCPZ-170 application, or AD9642BCPZ-170 equivalent, key selection criteria include sample rate matching (170 MSPS), LFCSP-32 package compatibility, LVDS output interface timing, and SNR/SFDR performance at RF input frequencies up to 305 MHz.
Technical Context
The AD9642BCPZ-170 implements a multistage differential pipelined ADC architecture with integrated error correction logic and a duty cycle stabilizer (DCS) for clock jitter resilience. Its analog front end supports 1.4–2.0 Vp-p differential input range with 2.5 pF input capacitance and 20 kΩ input resistance.
Digital interface uses a 3-wire SPI-compatible serial port (CSB, SCLK, SDIO) for register configuration and readback, while data is delivered via 14-bit DDR LVDS outputs (D0±–D13±) synchronized to DCO±. The device operates across −40°C to +85°C with thermal paddle soldered to AGND.
Key Specifications

Pinout & Package
The AD9642BCPZ-170 is housed in a 32-lead, 5 mm × 5 mm LFCSP package with exposed thermal paddle connected to AGND. Pin 0 (exposed paddle) is the analog ground reference and must be soldered to PCB ground plane for thermal and electrical integrity.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VIN+, VIN− | Differential analog input | Accepts balanced RF/IF signal; 20 kΩ input resistance and 2.5 pF capacitance define anti-alias filter design requirements. |
| CLK+, CLK− | Differential clock input | Supports CMOS/LVDS/LVPECL; DCS circuit compensates for duty cycle distortion to maintain aperture jitter ≤0.1 ps rms. |
| D0±–D13± | DDR LVDS data outputs | Deliver 14-bit samples on both clock edges; require matched trace lengths and 100 Ω differential termination. |
| DCO± | Data clock output | LVDS-sourced clock aligned to data edges; used by FPGA for source-synchronous capture with <0.7 ns skew. |
| CSB, SCLK, SDIO | SPI control interface | 3-wire serial port for configuring gain, test modes, and power-down states; operates up to 25 MHz SCLK. |
| AVDD, DRVDD | Separate analog/digital supplies | Both 1.8 V; AVDD powers core and reference, DRVDD drives LVDS outputs-enables independent supply filtering. |

FAQ
What is the maximum input frequency supported by the AD9642BCPZ-170?
The AD9642BCPZ-170 has a full-power bandwidth of 1000 MHz, enabling direct RF sampling of signals up to 305 MHz at −1 dBFS with 69.0 dBFS SNR. This makes the AD9642BCPZ-170 suitable for undersampling applications in broadband communications and spectrum monitoring systems where high-frequency signal fidelity is critical.
Does the AD9642BCPZ-170 require an external voltage reference?
No, the AD9642BCPZ-170 integrates a precision internal voltage reference, eliminating the need for external reference components. This simplifies system design, reduces BOM count, and maintains ±0.6 LSB integral nonlinearity over temperature-key for consistent ADC performance in field-deployed AD9642BCPZ-170 systems.
What is the purpose of the duty cycle stabilizer (DCS) in the AD9642BCPZ-170?
The DCS in the AD9642BCPZ-170 corrects duty cycle distortion in the input clock signal, ensuring stable aperture jitter (<0.1 ps rms) even with clocks exhibiting 40%–60% duty cycle variation. This preserves SNR and SFDR performance without requiring expensive, tightly controlled clock sources-directly benefiting AD9642BCPZ-170 implementations in cost-sensitive RF receivers.
How many pins does the AD9642BCPZ-170 package have, and what is its footprint?
The AD9642BCPZ-170 uses a 32-lead LFCSP package measuring 5 mm × 5 mm with an exposed thermal paddle. The paddle must be soldered to the PCB's analog ground plane to ensure proper thermal dissipation and electrical reference integrity-critical for maintaining the specified 71.2 dBFS SNR of the AD9642BCPZ-170 under continuous operation.
Can the AD9642BCPZ-170 interface directly with Xilinx or Intel FPGAs?
Yes, the AD9642BCPZ-170's DDR LVDS outputs (D0±–D13±) and DCO± clock are fully compatible with FPGA I/O standards including Xilinx SelectIO and Intel HPS. Its 100 Ω differential termination requirement and <0.7 ns DCO-to-data skew align with FPGA source-synchronous capture constraints-enabling robust, high-speed data acquisition in AD9642BCPZ-170–FPGA signal chains.
