China-based 14-bit 3 GSPS per channel dual-channel high-speed ADC with JESD204B interface, BGA196 package. Formerly JXA2421PPB, performance alternative to AD9208.
The JXA038 is a 14-bit resolution, up-to-3-GSPS-per-channel dual-channel high-speed ADC (formerly designated JXA2421PPB), benchmarked against ADI's AD9208. The device integrates two independent high-performance ADC cores for synchronous dual-channel signal sampling, making it ideal for multi-channel phased arrays, wideband communication receivers, and I/Q signal acquisition in EW systems.
Digital output uses a JESD204B high-speed serial interface supporting multi-lane configurable output rates, significantly reducing board-level trace count and simplifying PCB layout. On-chip integrated features include programmable gain, offset adjustment, and digital down-conversion (DDC), combined with a BGA196 package for compact system integration. Optimized power and thermal design suit dense deployment in multi-channel array systems.
The JXA038 has been performance-verified in multiple radar receivers, communication base stations, and test instruments. It is a high-grade China-based alternative to the AD9208. Standard lead time is approximately 6 weeks, significantly shorter than comparable imported products. FAE support includes reference designs and FPGA JESD204B IP core integration guidance.
