Product details
Overview
AD9229BCPZ-65 from Analog Devices is a quad-channel, 12-bit, 65 MSPS analog-to-digital converter with serial LVDS outputs, on-chip sample-and-hold, and 400 MHz full-power analog bandwidth. It operates from a single 3.0 V supply, delivers 69.0 dB SNR at 65 MSPS, and supports 780 Mbps LVDS data rates for ultrasound beam-forming and broadband communications systems.
For engineers reviewing the AD9229BCPZ-65 datasheet, AD9229BCPZ-65 pinout, AD9229BCPZ-65 application, or AD9229BCPZ-65 equivalent, this page provides verified specifications, industrial-temperature LFCSP package details, LVDS timing alignment support via DCO/FCO, and validated alternatives for multi-channel high-speed digitization.
Technical Context
The AD9229BCPZ-65 integrates four independent pipeline ADC cores sharing a common clock input and LVDS serializer architecture. Each channel features matched gain (±0.2% FS) and offset (±5 mV), with 10-clock-cycle pipeline latency and aperture jitter <1 ps rms.
It employs an internal 1.0 V reference (±16 ppm/°C drift) and supports differential analog inputs from 1 V p-p to 2 V p-p. The LVDS output interface includes dedicated DCO+/– and FCO+/– clocks for DDR capture, with data-to-data skew ±250 ps and propagation delay ≤7.9 ns.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad-channel, high-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9222BCPZ-65 | 12-bit, quad, 65 MSPS-but uses CMOS parallel outputs (48 pins/channel) instead of LVDS serial. | Requires 192+ data lines and tight length-matching; unsuitable for dense FPGA designs with limited I/O. | Select AD9222BCPZ-65 only when legacy parallel interfaces or lower EMI sensitivity outweigh routing complexity. |
| AD9629BCPZ-65 | 12-bit, quad, 65 MSPS with identical LFCSP-48 package and LVDS interface-but adds JESD204B option (not supported by AD9229BCPZ-65). | Enables direct connection to JESD204B-capable FPGAs; higher protocol overhead but scalable lane count. | Choose AD9629BCPZ-65 for new designs targeting JESD204B ecosystem compatibility and future upgrade path. |
Compared with AD9222BCPZ-65, AD9229BCPZ-65 saves >150 PCB traces and eliminates length-matching constraints; compared with AD9629BCPZ-65, it offers simpler timing implementation and lower FPGA resource usage due to absence of JESD204B link layer.

FAQ
What is the maximum analog input frequency supported by the AD9229BCPZ-65?
The AD9229BCPZ-65 has a full-power analog bandwidth of 400 MHz, meaning it maintains rated SNR and SFDR performance for input signals up to 400 MHz. This allows digitization of IF signals up to 70 MHz with high fidelity, as confirmed by FFT plots showing 68.5 dB SNR at fIN = 70 MHz and fSAMPLE = 65 MSPS in the official datasheet Rev. C.
Does the AD9229BCPZ-65 require external reference components?
No, the AD9229BCPZ-65 includes an internal 1.0 V reference with ±16 ppm/°C drift and supports 1 V p-p or 2 V p-p differential input ranges without external references. External reference pins (REFT/REFB/SENSE) are provided for optional precision configurations, but default operation uses the internal reference-verified in Table 1 and General Description sections of the datasheet.
How does the LVDS serial interface of the AD9229BCPZ-65 reduce system complexity?
The AD9229BCPZ-65 serializes each 12-bit ADC output into a 780 Mbps LVDS stream, replacing 48 parallel data lines per channel with just two differential pairs per ADC (D+/D–). Combined with DCO+/– and FCO+/– clocks, this cuts total digital I/O count by ~75%, eliminates trace length matching, and simplifies FPGA interface design-details confirmed in Functional Block Diagram and Digital Specifications tables.
What is the power consumption of the AD9229BCPZ-65 at its rated 65 MSPS speed?
The AD9229BCPZ-65 consumes 1350 mW at 65 MSPS, as specified in Table 1 under "Power Dissipation" (Full, VI test level). This includes 455 mA from AVDD and 33 mA from DRVDD. In power-down mode, dissipation drops to 3 mW-enabling rapid low-power states during idle periods without losing configuration.
Can the AD9229BCPZ-65 operate with a 50 MSPS sampling rate?
Yes, the AD9229BCPZ-65 is fully specified for 50 MSPS operation (AD9229-50 variant), with reduced power dissipation of 985 mW and maintained AC performance including 69.5 dB SNR at 2.4 MHz input. All timing, DC, and digital specifications remain valid across the 10–65 MSPS range, as documented in Tables 1–4 of the Rev. C datasheet.
