ADSP-21990: 高性能混合型信号DSP,160 MHz,4K字程序存储器RAM
ADSP-21990是ADI公司的首款高性能混合信号DSP产品。ADSP-21990集成了160 MHz、16位的ADSP-219x DSP内核和一个8通道、14位、20 MSPS的ADC(内置双采样保持放大器可实现同步采样)。该产品还集成了另外一些混合信号电路,包括一个精密片上电压基准以及上电复位(POR)电路。而所提供的各种控制外设可实现针对嵌入式控制和信号处理应用的单芯片解决方案。
The ADSP-21990 is the first high-performance mixed signal DSP product from ADI. The ADSP-21990 integrates a 160 MHz, 16-bit, ADSP-219x DSP core and an 8-channel, 14-bit, 20 MSPS ADC (with dual sample-and-hold amplifiers for simultaneous sampling). Additional mixed-signal integration includes a precision on-chip voltage reference, and a power-on-reset (POR) circuit. Various control peripherals are provided for single-chip solutions for embedded control and signal processing applications.
