• Manufacturer Part Number: max9963bjccq-td
• Description: Quad Low-power 500mbps Ate Driver/comparator
• Manufacturer: Maxim Integrated Products, Inc.

The MAX9963/MAX9964 four-channel, high-speed pin
electronics driver and comparator ICs for automatic
test equipment include, for each channel, a three-level
pin driver, a dual comparator, and variable clamps
(Figure 1). The driver features a -1.5V to +6.5V operat-
ing range and high-speed operation, including high-Z
and active termination (3rd-level drive) modes, which is
highly linear even at low-voltage swings. The comparator
provides low timing dispersion regardless of changes in
input slew rate and pulse width. The clamps provide
damping of high-speed DUT_ waveforms when the
device is configured as a high-impedance receiver.
Each of the four channels has high-speed, differential
inputs compatible with ECL, LVPECL, LVDS, and GTL

signal levels, with optional 100Ω differential input termi-
nations. Optional internal resistors at DATA_ and RCV_
provide differential termination of LVDS inputs. Optional
internal resistors at CH_ and CL_ provide the pullup
voltage and source termination for open-collector com-
parator outputs. These options significantly reduce the
discrete component count on the circuit board.
The MAX9963/MAX9964 are available in two grade
options. An A-grade version provides tighter matching
of gain and offset of the drivers, and tighter offset
matching of the comparators. This allows reference lev-
els to be shared across multiple channels in cost-sensi-
tive systems. A B-grade version provides lower cost for
system designs that incorporate independent reference
levels for each channel.
