News Release from: Texas Instruments (April 2001-March 2006) | Subject: DAC5686
Edited by the Electronicstalk Editorial Team on 12 May 2003
DAC supports four
wideband CDMA carriers
The programmable dual DAC5686 is a digital to analogue convertor supporting up to four wideband CDMA carriers that requires 50% less power when compared to other competitive solutions
Offering designers' three unique modes of operation as well as three separate clock modes, the DAC allows for a low input data rate with a programmable interpolation rate of 2-16x up to an output rate of 500Msample/s. The DAC is coupled with four additional devices to simplify the design time required for the wireless transceiver system of the basestation.

'By developing these adaptable analogue products for the transceiver system, TI is reducing the overall development cost for the basestation'.
In addition to providing solutions for the analogue transceiver system, TI offers high performance DSPs for the digital baseband and transcoding functions as well as logic solutions that enable designers to increase data throughput, shrink form factors and reduce power consumption.
TI's power management products range from discrete devices to modular approaches, addressing the various technical wireless infrastructure system challenges.
The DAC5686 offers excellent performance for single and multicarrier WCDMA operation.
For single carrier WCDMA signals, the DAC5686 has demonstrated ACPR better than 68dBc at frequencies up to 122.88MHz.
For dual carrier WCDMA signals, ACPR better than 71dBc is possible up to 61.44MHz.
The DAC5686 can be used in three clock modes - PLL mode, DAC clock mode and data/DAC clock mode.
It is also configurable in three modes of operation.
Dual-channel operation is used for baseband modulation or a two-channel digital IF system.
The dual DACs and datapaths operate independently.
The interpolation filters increase the DAC update rate, resulting in reduced sin x/x roll off and relaxed requirements for analogue post-filtering.
In quadrature modulation mode the device converts a complex digital baseband signal to IF frequency after upsampling, and is used for IF greater than 50MHz.
Finally, in single sideband upconversion mode the complex IF output allows offset of signal after analogue quadrature modulator, placing LO feedthrough and unwanted sideband signal out of band.
