EVAALVUAAILTAIOBNLEKIT
Dual 1.1Gbps Pin Electronics with Integrated
PMU and Level-Setting DACs
General Description
The MAX9979 fully integrated, high-performance, dual-
channel pin electronics integrates multiple automatic test
equipment (ATE) functions into a single IC, including dri-
ver/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 compara-
tor, dynamic clamps, a versatile PMU, an active load, a
high-voltage (VHH) programmable level, and 14 indepen-
dent level-setting DACs. The MAX9979 features program-
mable 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 adjust-
ment, 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 program-
mable 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 pro-
vide extremely low timing variation over changes in slew
rate, pulse width, and overdrive voltage. In high-imped-
ance 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 out-
puts. 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 dis-
sipation 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.
