DAC5682ZIRGCT General Description

The DAC5682Z is a dual-channel 16-bit 1.0 GSPS DAC with wideband LVDS data input, integrated 2x/4x interpolation filters, onboard clock multiplier, and internal voltage reference. The DAC5682Z offers superior linearity, noise, crosstalk, and PLL phase noise performance.

The DAC5682Z integrates a wideband LVDS port with on-chip termination. Full-rate input data can be transferred to a single DAC channel, or half-rate and 1/4-rate input data can be interpolated by onboard 2x or 4x FIR filters. Each interpolation FIR is configurable in either low-pass or high-pass mode, allowing selection of a higher order output spectral image. An on-chip delay lock loop (DLL) simplifies LVDS interfacing by providing skew control for the LVDS input data clock.

The DAC5682Z allows both complex or real output. An optional Fs/4 coarse mixer in complex mode provides coarse frequency upconversion and the dual DAC output produces a complex Hilbert Transform pair. An external RF quadrature modulator then performs the final single sideband up-conversion. The interpolation filters and complex coarse mixers efficiently provide frequency plan flexibility while enabling higher output DAC rates to simplify image rejection filtering.

The DAC5682Z is characterized for operation over the industrial temperature range of 40°C to 85°C and is available in a 64-pin QFN package. Other single-channel members of the family include the interpolating DAC5681Z and the noninterpolating DAC5681.

The parcel came quickly literally days 10, everything is well packed. I recommend

It rolls that good... makes the 5 watt columns of sven 315... variable resistor with power on and off... the sound is regulated not throughout the resistor range... and then at the very end of the hooker and at the full volume... in general, adjustment The sound is about a quarter of the entire range .. apparently not correctly selected the nominal resistor .. delivery 5 days... flew straight into the box. even go to the post office did not have to... barred the bluetooth column the most it... a little not enough bass .. knows how to correct it .. i will smoke datashit
