AD9163

Data Sheet 16-Bit, 12 GSPS, RF DAC and Digital Upconverter AD9163 FEATURES DAC update rate up to 12 GSPS (minimum) Direct RF synthesis at 6 GSPS (minimum) DC to 3 GHz in nonreturn-to-zero (NRZ) mode DC to 6 GHz in 2× NRZ mode 1.5 GHz to 7.5 GHz in Mix-Mode Selectable interpolation 6×, 8×, 12×, 16×, 24× Excellent dynamic performance APPLICATIONS Broadband communications systems DOCSIS 3.1 cable modem termination system (CMTS)/ video on demand (VOD)/edge quadrature amplitude modulation (EQAM) Wireless communications infrastructure MC-GSM, W-CDMA, LTE, LTE-A, point to point GENERAL DESCRIPTION The wide bandwidth of up to 1 GHz and the complex NCO and digital upconverter enable dual band and triple band direct RF synthesis of wireless infrastructure signals, eliminating costly analog upconverters. Wide analog bandwidth capability combines with high dynamic range to support DOCSIS 3.1 cable infrastructure compliance from the minimum of one carrier up to 1 GHz of signal bandwidth, making it ideal for cable multiple dwelling unit (MDU) applications. A 2× interpolator filter (FIR85) enables the AD9163 to be configured for lower data rates and converter clocking to reduce the overall system power and ease the filtering requirements. In Mix-Mode™ operation, the AD9163 can reconstruct RF carriers in the second and third Nyquist zones up to 7.5 GHz while still maintaining exceptional dynamic range. The output current can be programmed from 8 mA to 38.76 mA. The AD9163 data interface c...
