AD9875: 10-Bit Broadband Modem Mixed Signal Front End
AD9875 简述
The AD9875 (10-bit) and AD9876 (12-bit) are single supply broadband modem mixed signal front end ICs. They contain the transmit path Interpolation Filter and DAC, and the receive path PGA, LPF and ADC required for a variety of broadband modem applications. Also on-chip is a PLL clock multiplier that provides all required clocks from a single crystal or clock input.
