Product details
Overview
AD9230BCPZ-250 from Analog Devices is a 12-bit, 250 MSPS analog-to-digital converter optimized for wideband communications and radar subsystems. It delivers 64.9 dBFS SNR at 70 MHz input, 10.4 ENOB, −79 dBc SFDR, and operates from a single 1.8 V supply with 700 MHz analog bandwidth. Its LVDS DDR/SDR outputs interface directly to FPGAs in cable reverse-path and power amplifier linearization systems.
For engineers reviewing the AD9230BCPZ-250 datasheet, AD9230BCPZ-250 pinout, AD9230BCPZ-250 application, or AD9230BCPZ-250 equivalent, key selection considerations include its 250 MSPS sampling rate, 1.8 V dual-supply operation, programmable input range (1.0–1.5 V), LVDS output format flexibility (offset binary/twos complement/Gray), and integrated clock duty cycle stabilizer for jitter-sensitive RF digitization.
Technical Context
The AD9230BCPZ-250 implements a high-speed pipeline ADC architecture with on-chip track-and-hold and voltage reference, eliminating external decoupling requirements. Its differential analog inputs support 1.25 V nominal full-scale range and 700 MHz full-power bandwidth, enabling direct sampling of IF signals up to 170 MHz.
Digital interface uses ANSI-644-compliant LVDS outputs with selectable SDR or DDR mode, synchronized by an integrated data clock output (DCO±). Serial port control (SPI) enables runtime configuration of data format, DCS enable/disable, gain adjustment, and test pattern generation without external logic.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed ADC applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| AD9233BCPZ-250 | 12-bit, 250 MSPS, but uses 3.3 V digital supply (DRVDD) and lacks integrated reference; requires external REF and decoupling. | Higher power consumption (520 mW) and larger board footprint due to external reference and buffer components. | Select when legacy 3.3 V FPGA I/O domains preclude 1.8 V LVDS compatibility or when external reference tuning is required. |
| ADS54J60IRGCT | 14-bit, 500 MSPS, JESD204B serial output; no parallel LVDS bus; requires serializer/deserializer link and FPGA JESD IP. | Enables higher resolution and sampling rate but adds protocol stack complexity and FPGA resource overhead. | Select when system demands >12-bit ENOB or needs JESD204B backplane connectivity instead of parallel LVDS interface. |
Compared with AD9233BCPZ-250, AD9230BCPZ-250 reduces component count and power via integrated reference and 1.8 V operation; compared with ADS54J60IRGCT, it offers simpler FPGA integration and lower latency but trades off resolution and serial interface scalability.

FAQ
What is the maximum analog input frequency supported by the AD9230BCPZ-250?
The AD9230BCPZ-250 features a 700 MHz full-power analog bandwidth, enabling accurate digitization of signals up to 170 MHz while maintaining specified SNR and SFDR performance. This supports undersampling architectures for IF frequencies in L-band and S-band radar and communications systems without requiring external anti-alias filtering beyond basic reconstruction.
Does the AD9230BCPZ-250 require external reference components?
No, the AD9230BCPZ-250 integrates a precision voltage reference and track-and-hold circuit, eliminating the need for external reference ICs, decoupling capacitors, or buffer amplifiers. This reduces bill-of-materials cost and PCB area while improving system-level SNR consistency across temperature and unit-to-unit variation.
How does the LVDS DDR mode affect data interface timing for the AD9230BCPZ-250?
In LVDS DDR mode, the AD9230BCPZ-250 transmits alternating 6-bit nibbles on each clock edge using the same 12-pin LVDS bus, halving the required data rate per pin versus SDR mode. The integrated DCO± output maintains < ±0.5 ns data-to-clock skew, enabling reliable capture in FPGA I/O banks with DDR input registers without external delay tuning.
Can the AD9230BCPZ-250 operate with a single 1.8 V supply?
Yes, the AD9230BCPZ-250 operates from two independent 1.8 V supplies: AVDD for the analog core and DRVDD for the digital outputs. Both rails must be regulated to 1.8 V ±0.1 V, but they may share a single 1.8 V source if adequate PSRR and isolation between analog and digital ground planes are maintained per layout guidelines.
What is the latency of the AD9230BCPZ-250, and is it deterministic?
The AD9230BCPZ-250 has a fixed latency of exactly 7 clock cycles from analog input to valid LVDS output data, regardless of operating mode (SDR/DDR) or configuration settings. This deterministic latency enables precise time-of-flight calculations in radar beamformers and synchronous multi-channel sampling in phased-array systems.
