Test Set-up Connection (Onboard LMK04828 Clock)

1. Connect J17 connector of ADC32Jxx/ADC34Jxx EVM to J4 connector of TSW14J56 EVM (or
TSW14J50 if desired)
2. Connect 5V to the J11 supply input connector of the TSW14J56 and 5V to the J20 supply input
connector of the ADC32Jxx/34Jxx EVM
3. Connect a USB cable from the ADC32J/34Jxx EVM to the PC for SPI programming. The
ADC32J/34Jxx EVMs require some programming for the on board clock requirements of the
JESD204B interface.
4. Provide a sine wave for the analog input at J3 or J6 of ADC32Jxx EVM and J1, J3, J5, or J7 of the
ADC34Jxx EVM.
5. Connect USB cable from the TSW14J56 to the programming computer
6. Verify the following jumper connections on the ADC32J/34Jxx EVM
• JP1 – 1,2 default condition PDN is low
• JP2, JP3, JP4, JP5 – closed – default condition for SPI connection
• JP6 – Closed – power for the onboard clock
• JP8 – 2,3 – default condition to select USB port for SPI communication
• JP9 – 1,2 – default condition select LDO power
• JP10 – 1,2 – default condition select LDO power
• JP12 – 1,2 – default condition select LDO power
• JP13 – 1,2 – default condition select LDO power
