Description

General part information

ADSP-21990 Series

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.
