boards designed for multichannel data acquisition +applications. The boards feature a multi-mode ADC that supports 8-bit, 12-bit, +and 14-bit resolution modes with sampling rates between 105-1000 MSPS. They +provide flexible input configuration options with both single-ended and +differential analog inputs, enabling direct interfacing with a wide variety of +RF and baseband signal sources. The boards include integrated signal +conditioning and timing circuitry for seamless operation. Hardware and software +controls enable users to optimize the ADC performance for their specific +application requirements.

+evaluation board has four input channels that supports single-ended to +differential conversion with the use of a balun. By default, all input channels +1-4 (SMAs J3, J5, J6 and J7) are balun-coupled. Alternatively, input channel 1 +(SMAs J3 and J4) can be configured to differential to differential conversion, +and input channel 2 (SMA J5) can be configured to single-ended to differential +conversion using the onboard :adi:`LTC6419` high-speed differential +ADC driver. + +Refer to the table below for the optional amplifier configuration. + ++---------------------------------+------------------------------------------+---------------------------------+------------------------------+------------------------------+ +| **Analog input channel number** | **Default Input Driver, AC/DC coupling** | **Signal type on Input/Output** | **Install** | **Uninstall** | ++=================================+==========================================+=================================+==============================+==============================+ +| 1 | LTC6419, DC coupling, Unity Gain | Differential/Differential | R41, R42, R44, R45, R60, R61 | C51, C52, R23, R24, R56, R57 | ++---------------------------------+------------------------------------------+---------------------------------+------------------------------+------------------------------+ +| 2 | LTC6419, DC coupling, Unity Gain | Single-Ended/Differential | R46, R58, R59 | C53, R54, R55, R23, R24 | ++---------------------------------+------------------------------------------+---------------------------------+------------------------------+------------------------------+ + +Analog Input Vcm +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +the :adi:`HMCAD1511` / :adi:`HMCAD1520` supplies the +common mode voltage at half-supply (0.9V) for all analog input channels. No +external supply is needed for the input Vcm. + +Power supply +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +The power supply comes from the FMC connector, given by the FPGA. + +.. warning:: + The recommended VADJ value for each FPGA carrier can be found in the + corresponding README.md file :git-hdl:`here `. + +Both the :adi:`HMCAD1520` and :adi:`HMCAD1511` are being supplied by +:adi:`ADM7154` with 1.8V. The board can be modified to bypass the LDO so the +:adi:`HMCAD1520` and :adi:`HMCAD1511` are directly supplied by the +:adi:`LTM8078` DC-DC regulator. To do this, change components C3 to 100uF, R6 +to 200k, and install a ferrite bead to R9. Also, uninstall R8 and R10. + +The supply rails for other components on the board (crystal, amplifier, etc) +are isolated to the :adi:`HMCAD1520` and :adi:`HMCAD1511` supply rail. Refer to +the board schematics for more info. + +Clock +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ +The :adi:`HMCAD1520-EBZ` evaluation board uses an external 1GHz +clock source on SMA J1 as default. + +The :adi:`HMCAD1511-EBZ` evaluation board has an on-board 1GHz +crystal for clocking the :adi:`HMCAD1511`.
