PRODUCT DESCRIPTION
The AD9875 is a single-supply broadband modem mixed-signal front end (MxFE) IC. The devices contain a transmit path Interpolation Filter and DAC, and a receive path PGA, LPF, and ADC supporting 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. The AD9875 provides 10-bit converter performance on both the Tx and Rx paths.
