可扩展的20.8 GSPS 12位数字化仪参考设计Reference Design For Scalable 20.8 GSPS 12 Bit Digitizers
➀ 德州仪器（TI）的参考设计TIDA-010128展示了使用时间交错配置的RF采样ADC的高性能20.8 GSPS采样系统。
➁ 该设计通过利用ADC12DJ5200RF设备的无噪声孔径延迟调整功能解决了偏移、增益和采样时间不匹配等挑战。
➂ 设计支持JESD204B，最多32个通道，并包括低噪声时钟发生器和实现超过85％效率的配套电源参考设计。
➀ The reference design TIDA-010128 by Texas Instruments (TI) presents a high-performance 20.8 GSPS sampling system using RF-sampling ADCs in a time-interleaved configuration.
➁ This design tackles challenges like offset, gain, and sampling time mismatch by utilizing the noiseless aperture delay adjustment feature of the ADC12DJ5200RF device.
➂ The design supports JESD204B with up to 32 lanes and includes a low-noise clock generator and a companion power reference design achieving over 85% efficiency.
