The DAC5682Z offers superior linearity, noise, crosstalk, and PLL phase – 8 Sample Input FIFO noise performance. – Interleaved I/Q Data for Dual-DAC Mode The DAC5682Z integrates a wideband LVDS port • High Performance with on-chip termination. Full-rate input data can be – 73-dBc ACLR WCDMA TM1 at 180 MHz transferred to a single DAC channel, or half-rate and • 2x-32x Clock Multiplying PLL/VCO 1/4-rate input data can be interpolated by onboard 2x or 4x FIR filters. Each interpolation FIR is • 2x or 4x Interpolation Filters configurable in either low-pass or high-pass mode, – Stopband Transition 0.4 to 0.6 Fdata allowing selection of a higher order output spectral – Filters Configurable in Either Low-Pass or image. An on-chip delay lock loop (DLL) simplifies High-Pass Mode LVDS interfacing by providing skew control for the LVDS input data clock. – Allows Selection of Higher Order Image • Fs/4 Coarse Mixer Device Information(1) • On-Chip 1.2-V Reference PART NUMBER PACKAGE BODY SIZE (NOM) • Differential Scalable Output: 2 to 20 mA DAC5682Z VQFN (64) 9.00 mm × 9.00 mm • Package: 64-Pin 9-mm × 9-mm QFN (1) For all available packages, see the orderable addendum at the end of the data sheet. 2 Applications 3-Carrier WCDMA TM1 With a Gap • Cellular Base Stations • Broadband Wireless Access (BWA) • WiMAX 802.16 • Fixed Wireless Backhaul • Cable Modem Termination System (CMTS) 1 An IMPORTANT NOTICE at the end of this data sheet addresses availability, warranty, changes, use in safety-critical applications, intellectual property matters and other important disclaimers.
