Description

The MAX9957 dual driver IC for automatic test equipment (ATE) memory applications offers three-level drive capability, high-speed switching, low timing dispersion, and features voltage-controlled waveform shaping to enhance edge-placement accuracy and minimize distortion. It also provides tight matching of gain and offset. The MAX9957 buffers reference voltage inputs for each channel with nominal -1V to +3.5V voltage ranges. High-speed differential control inputs, compatible with CML levels, are provided for each channel. Static power dissipation is only 1500mW per channel with nominal -5V and +7V supplies. The MAX9957 power dissipation at 2Gbps toggling is only 1550mW/channel. The MAX9957D power dissipation at 2.4Gbps is only 1850mW/channel.

The MAX9957 is available in a 10mm x 10mm x 1mm, 64-pin TQFP package with an exposed pad, inverted die pad for ease of heat removal.
