Dual DCL with Integrated Level Setters
General Description
The MAX19000 is a fully integrated, dual-channel, high-
performance pin-electronics driver/comparator/load
(DCL) with built-in level setters, and is ideal for memory
and SOC ATE systems. Each MAX19000 channel
includes a three-level pin driver, a window comparator,
dynamic clamps, an active load, programmable cable-
loss compensation, and built-in programmable level
setters.
The driver features a wide -2V to +6V operating range
and a data rate of 1200Mbps at +2V operation. The driver
includes high impedance, active termination (3rd-level
drive), and is highly linear even at low-voltage swings.
The window comparators provide extremely low timing
variation with changes in slew rate, common mode, pulse
width, and overdrive. The active load has an extended
I
OH
and I
OL
current range, providing up to 20mA. The
dynamic clamps provide damping of high-speed DUT
waveforms when the DCL is in high-impedance receive
mode. A serial interface configures the device, easing
PCB signal routing.
The MAX19000 is available in a 64-pin TQFP package
with an exposed pad.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute
maximum rating conditions for extended periods may affect device reliability.
