1 / 58 page DAC5681Z www.ti.com SLLS865F – AUGUST 2007 – REVISED AUGUST 2012 16-BIT, 1.0 GSPS 2x-4x INTERPOLATING DIGITAL-TO-ANALOG CONVERTER (DAC) Check for Samples: DAC5681Z 1 FEATURES DESCRIPTION The DAC5681Z is a 16-bit 1.0 GSPS digital-to-analog • 16-Bit Digital-to-Analog Converter (DAC) converter (DAC) with wideband LVDS data input, • 1.0 GSPS Update Rate integrated 2x/4x interpolation filters, on-board clock • 16-Bit Wideband Input LVDS Data Bus multiplier and internal voltage reference. The DAC5681Z offers superior linearity, noise, crosstalk – 8 Sample Input FIFO and PLL phase noise performance. • High Performance The DAC5681Z integrates a wideband LVDS port – 73 dBc ACLR WCDMA TM1 at 180 MHz with on-chip termination. Full-rate input data can be • 2x-32x Clock Multiplying PLL/VCO transferred to a single DAC channel, or half-rate and • 2x or 4x Interpolation Filters 1/4-rate input data can be interpolated by on-board 2x or 4x FIR filters. Each interpolation FIR is – Stopband Transition 0.4–0.6 Fdata configurable in either Low-Pass or High-Pass mode, – Filters Configurable in Either Low-Pass or allowing selection of a higher order output spectral High-Pass Mode image. An on-chip delay lock loop (DLL) simplifies – Allows Selection of Higher Order Image LVDS interfacing by providing skew control for the LVDS input data clock. • On Chip 1.2 V Reference • Differential Scalable Output: 2 to 20 mA The DAC5681Z is characterized for operation over the industrial temperature range of –40°C to 85°C • Package: 64-Pin 9 × 9 mm QFN and is available in a 64-pin QFN package. Other members of the family include the dual-channel, APPLICATIONS interpolating DAC5682Z and the single-channel, non- • Cellular Base Stations interpolating DAC5681. • Broadband Wireless Access (BWA) • WiMAX 802.16 • Fixed Wireless Backhaul • Cable Modem Termination System (CMTS) ORDERING INFORMATION TA ORDER CODE PACKAGE DRAWING/TYPE(1) (2) (3) TRANSPORT MEDIA QUANTITY DAC5681ZIRGCT Tape and Reel 250 –40°C to 85°C RGC / 64QFN Quad Flatpack No-Lead DAC5681ZIRGCR Tape and Reel 2000 (1) Thermal Pad Size: 7,4 mm × 7,4 mm (2) MSL Peak Temperature: Level-3-260C-168 HR (3) For the most current package and ordering information, see the Package Option Addendum at the end of this document, or see the TI website at www.ti.com. 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
