The AD9873 is a mixed signal front-end developed for broadband communications applications. It includes a complete 12-bit, 232 MSPS digital up-converter, 12-bit ADC, 10-bit ADC, two 8-bit ADCs, and two sigma-delta control DACs. Although it was developed for cable set top box/modem applications, it provides a combination of price and performance characteristics that are ideal for other broadband communication applications such as power line and wireless modems.
