JXA2421PPB
14-Bit, Dual-Channel, 3GSPS RF Sampling ADC — Pin-Compatible Alternative to AD9208
Product Overview
The JXA2421PPB is a 14-bit,-channel, 3GSPS-per-channel-speed pipelined ADC with direct RF sampling architecture and JESD204B/C high-speed serial interfaces. This device enables direct digitization of high-frequency analog signals, significantly simplifying front-end analog circuit design. It is ideal for broadband communications, radar, and electronic warfare applications.
Built on an advanced CMOS process, the JXA2421PPB integrates a high-precision voltage reference, on-chip calibration engine, and digital signal processing blocks to deliver excellent linearity and noise performance across the full temperature and supply voltage range. The JESD204B/C interface supports Subclass 1 deterministic latency, enabling multi-chip synchronization for phased array and other large-scale array applications.
By selecting the JXA2421PPB, you gain performance on par with leading imported flagship ADCs while enjoying 6-week-day lead times, local FAE technical support, and flexible supply assurance. As a pin-to-pin compatible alternative to the AD9208, it enables rapid migration without hardware redesign—helping you reduce supply chain risk and accelerate time-to-market.

Application Areas
AD9208 Pin-Compatible Alternative
The JXA2421PPB is a functionally compatible alternative to the AD9208 high-speed ADC, matching key specifications including 14-bit-bit resolution, dual-channel 3GSPS sampling, and JESD204B/C interface.
This device offers pin-to-pin compatibility, enabling customers with existing AD9208-based hardware to migrate without PCB redesign—only software configuration verification is required. This significantly reduces validation costs and timeline. On-chip calibration ensures temperature drift stability and long-term reliability, meeting international performance standards.
Most importantly, unlike imported devices with 16–26 week lead times and supply uncertainty, the JXA2421PPB delivers a stable ~6-week lead time backed by Shenxin Microchip's professional FAE support team—ensuring your project never waits for parts.
