PRODUCT DESCRIPTION
The AD9876 is a single-supply broadband modem mixed-signal front end (MxFE) IC. The device contains 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 AD9876 provides 12-bit converter performance on both the Tx and Rx path.
