MAX9979

MAX9979 19-4134; Rev 6; 8/11 EVAALVUAAILTAIOBNLEKIT Dual 1.1Gbps Pin Electronics with Integrated PMU and Level-Setting DACs General Description The MAX9979 fully integrated, high-performance, dualchannel pin electronics integrates multiple automatic test equipment (ATE) functions into a single IC, including driver/comparator/load (DCL), parametric measurement unit (PMU), and built-in (16-bit) level-setting digital-to-analog converters (DACs). The device is ideal for memory and SOC tester applications. Each channel includes a fourlevel pin driver, window comparator, differential comparator, dynamic clamps, a versatile PMU, an active load, a high-voltage (VHH) programmable level, and 14 independent level-setting DACs. The MAX9979 features programmable cable-droop compensation for the driver output and for the comparator input, adjustable driver output resistance that allows optimal performance over typical data-path transmission-line variations, slew-rate adjustment, and a programmable high-voltage driver output. The MAX9979 driver features a wide 8V (-1.5V to +6.5V) high-speed operating voltage range and a VHH programmable range of up to +13V. Operation modes include high-impedance, active-termination (3rd-level drive) and VHH (4th-level drive) modes. The device is highly linear even at low voltage swings. The driver provides highspeed differential control inputs compatible with most high-speed logic families. The window comparators provide extremely low timing variation ove...
