Product Details
The MAX9979 fully integrated, high-performance, dual-channel 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 four-level 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 high-speed differential control inputs compatible with most high-speed logic families. The window comparators provide extremely low timing variation over changes in slew rate, pulse width, and overdrive voltage. In high-impedance mode, the MAX9979 features dynamic clamps that dampen high-speed device-under-test (DUT) waveforms. The 20mA active load facilitates fast contact testing when used in conjunction with the comparators, and functions as a pullup/pulldown for open-drain/collector DUT outputs. The PMU offers five current ranges from ±2µA to ±50mA and can force and measure current or voltage. An SPI™-compatible serial interface configures the MAX9979.
The MAX9979 is available in a small footprint, 68-pin (10mm x 10mm x 1mm) TQFN-EP-IDP package with exposed pad on the top for easy heat removal. Power dissipation is 1.2W per channel (typ) over the full operating voltage range with the active load disabled. The MAX9979 operates over an internal die temperature range of +40°C to +100°C and provides a temperature monitor output.
