Presentation Transcript

  1. DAC5688 EVM testing

  2. DAC5688 EVM Equipments • 2x Signal Generator with 1GHz output • 1x Spectrum analyzer • 3x rail power supply with 1.8V, 3.3V, and 5V • 4x SMA-SMA cable (2x Gore cable if possible) • 1 USB cable • 6x Banana to Banana cable • 1x TSW3100 board

  3. DAC5688 EVM Connections • Supply 1.8V, 3.3V, and 5V to the EVM board through J13/J14, J15/J16 and J10/J11. • Connect clock signal generator to J20 through SMA cable (Gore cable preferred). • Connect LO signal generator to J23 through SMA cable. • Connect Spectrum analyzer to J6 through SMA cable (Gore cable preferred). • Connect TSW3100 CMOS clock input (J73 on TSW3100) to J21 of DAC5688 EVM through SMA cable.

  4. Equipment set up • Clock source sig gen = 737.28MHz with 1.6V of power. • LO source sig gen = 2030MHz with 10dBm of power. • Spectrum analyzer: • Fc = 2.17GHz • RBW=30kHz, VBW=300kHz, SWT = 2s • CP/ACP stanard = W-CDMA 3GPP FWD • Adjust reference level • Noise correction on

  5. DAC5688 EVM Programming Load settings: PLL off.txt

  6. TSW3100 Multi-tone setup (single tone at 5.1MHz)

  7. TSW3100 software WCDMA

  8. Spectrum Analyzer Setup
