    Reference Voltage Options
    The MAX5858A EV kit supports both internal and exter-
    nal reference configurations. The internal reference
    voltage can be accessed at the REFO pad. The EV kit
    also accepts an external reference voltage at the REFO
    pad to set the full-scale analog-output signal level.
    Jumper JU5 selects the reference voltage options for
    the EV kit. Table 5 lists the jumper selection.
    Evaluating the MAX5858
    The MAX5858A EV kit also evaluates the pin-compatible
    MAX5858. Refer to the MAX5858 data sheet for more
    details on the MAX5858 functions. To evaluate the
    MAX5858, replace U1 with the MAX5858 and install a
    shunt on jumper JU4.
    Evaluating the MAX5856A
    The MAX5858A EV kit also evaluates the MAX5856A.
    Refer to the MAX5856A data sheet for more details on
    the MAX5856A functions. To evaluate the MAX5856A,
    the following component changes on the MAX5858A
    EV kit are necessary:
    Replace U1 with the MAX5856A.
    Install a shunt on J1-3 and J1-4.
    Install a shunt on J1-5 and J1-6.
    Install a shunt on J1-23 and J1-24.
    Install a shunt on J1-25 and J1-26.
    See Tables 6 and 7 for the data bits of the
    MAX5856A, with respect to header J1 on the
    MAX5858A EV kit.
    PLL Clock Multiplier (MAX5858A and
    MAX5856A only)
    The MAX5858A (10 bit) and MAX5856A (8 bit) feature a
    PLL clock multiplier that generates and distributes all
    internally synchronized high-speed clock signals
    required by the input data latches, interpolation filters,
    and DAC cores. Jumper JU4 sets the PLL clock multi-
    plier options. Table 8 lists the jumper selection.
    Clock
    The MAX5858A EV kit features two input clock options: a
    single-ended input clock applied to CLKIN or a differen-
    tial clock applied to CLKD. When evaluating the
    MAX5858A or the MAX5856A, CLKIN is used in PLL
    enabled mode, and CLKD is used in PLL disabled
    mode. The clock signal applied to the CLKIN SMA input
    connector has to meet CMOS logic-level requirements.
    When evaluating the MAX5858, only the CLKD SMA input
    connector is used. Jumpers JU1, JU4, JU10, and JU11
    set the input clock mode for the MAX5858A. Table 9 lists
    the jumper configurations.
