Evaluation Module For Dual 16Bit 625MSPS Communications DAC
The is a circuit board that allows designers to evaluate the performance of Texas Instruments" dual-channel 16-bit 625 MSPS DAC3282 digital-to-analog converter DAC with 8-byte wide DDR LVDS data input, integrated 2x interpolation filter and an additional sinc correction filter. The EVM provides a flexible environment to test the DAC3282 under a variety of clock, and input conditions. For ease of use as a complete RF transmit solution the DAC3282EVM includes the CDCE62005 clock generator/jitter cleaner for clocking the DAC3282 as well as a TRF7304 50MHz to 6GHz quadrature modulator for upconverting I/Q ouputs from the DAC to real signals at RF.
The EVM can be used along with TSW3100 to perform a wide range of test procedures. The TSW3100 generates the test patterns which are fed to the DAC3282 through a 1.25 GSPS LVDS port. The DAC3282EVM clock chip can be used to synchronize the TSW3100 board to DAC3282EVM.
