The TSW3084EVM Evaluation Module is a circuit board that allows system designers to evaluate the combined performance of Texas Instruments' transmit signal chain with the LMK04806B low noise clock generator/jitter cleaner. For ease of use as a complete RF transmit solution the TSW3084EVM includes the LMK04806B for clocking the DAC3484 digital-to-analog converter (DAC), as well as two TRF3705 for up-converting the I/Q outputs from the 4-channel DAC to RF carriers.
The DAC3484 is a four-channel, ultra-low power 16-bit 1.25 GSPS DAC with an efficient multiplexed 16-bit wide bus capable of 312MSPS per DAC input rates.
The TRF3705 is a high performance complex RF modulator with a 300 MHz to 4 GHz output range.
The LMK04806B is a low noise clock generator and jitter cleaner capable of jitter below 150fs rms and output frequencies up to 1300MHz.
The EVM can be used along with the TSW3100/TSW1400 pattern generator to perform a wide range of test procedures to the LVDS port up to a maximum rate of 1.25 GSPS. The TSW1406 can be used for low cost, simple patterns up to 1 GSPS. Besides providing a high-quality, low jitter DAC sampling clock to the DAC3484, the LMK04806B also provides FPGA clocks to the TSW1400/TSW1406/TSW3100 as an FPGA reference clock. The transmit RF signal path also includes an amplifier and programmable attenuator.
