Product Summary
The AD9878BST is a single-supply, cable modem/set-top box, mixed-signal front end. The AD9878BST contains a transmit path interpolation filter, a complete quadrature digital upconverter, and a transmit DAC. The receive path contains dual 12-bit ADCs and a 10-bit ADC. All internally required clocks and an output system clock are generated by the phase-locked loop (PLL) from a single crystal oscillator or clock input. The applications of the AD9878BST include Cable set-top boxes and Cable and wireless modems.
