... The MAX5889 digital inputs accept LVDS voltage lev- els, and the flexible clock input can be driven differen- tially or single-ended, AC- or DC-coupled. The MAX5889 is available in a 68-pin QFN package with an exposed paddle (EP) and is specified for the extended (-40°C to +85°C) temperature range. ...

... AGND with a 0.1µF capacitor. The REFIO output resistance is 10kΩ. Buffer REFIO with a high-input- impedance amplifier when using reference source for external circuitry. The MAX5889’s reference circuit (Figure 1) employs a control amplifier to regulate the full-scale current for the differential current outputs of the DAC. ...

... The MAX5889 features a power-down mode that reduces the DAC’s power consumption. Set PD high to power down the MAX5889. Set PD low or leave uncon- nected for normal operation. When powered down, the MAX5889 overall power con- sumption is reduced to less than 13µW. The MAX5889 requires 350µ ...

... OUTN to AGND. Operating the MAX5889 single-ended is not recommended because 25Ω it degrades the dynamic performance. The distortion performance of the DAC depends on the TO DAC load impedance. The MAX5889 is optimized for 50Ω 25Ω differential double termination. Using higher termination 0.1µF impedance degrades distortion performance and CLKN increases output noise voltage. 50Ω ...

... The exposed pad must be soldered to the ground plane of the PC board. Thermal efficiency is 25Ω not the key factor, since the MAX5889 features low- power operation. The exposed pad ensures a solid ground connection between the DAC and the PC board’s ground layer. ...

... The two-tone IMD is the ratio expressed in dBc (or dBFS) of the worst 3rd-order IMD differential product to either output tone. The two-tone IMD performance of the MAX5889 is tested with the two individual output Glitch Impulse tone levels set to at least -6.5dBFS. Adjacent Channel Leakage Power Ratio (ACLR) ...
