Maxim MAX9963BDCCQ Quad, low-power, 500mbps ate driver/comparator Datasheet

19-2977; Rev 1; 1/04
Quad, Low-Power, 500Mbps
ATE Driver/Comparator
The MAX9963/MAX9964 four-channel, low-power, highspeed pin electronics driver and comparator ICs
include, for each channel, a three-level pin driver, a dual
comparator, and variable clamps. The driver features a
wide voltage range and high-speed operation, includes
high-Z and active-termination (3rd-level drive) modes,
and is highly linear even at low-voltage swings. The dual
comparator provides low dispersion (timing variation)
over a wide variety of input conditions. The clamps provide damping of high-speed DUT waveforms when the
device is configured as a high-impedance receiver.
High-speed, differential control inputs compatible with
ECL, LVPECL, LVDS, and GTL levels are provided for
each channel. ECL/LVPECL or flexible open-collector
outputs are available for the comparators.
The A-grade version provides tight matching of gain
and offset for the drivers and comparators, allowing reference levels to be shared across multiple channels in
cost-sensitive systems. For system designs that incorporate independent reference levels for each channel,
the B-grade version is available at reduced cost.
Optional internal resistors at the high-speed inputs provide differential termination of LVDS inputs, while
optional internal resistors provide the pullup voltage
and source termination for open-collector comparator
outputs. These features significantly reduce the discrete component count on the circuit board.
Low-leakage, slew rate, and tri-state/terminate controls
are operational configurations that are programmed
through a 3-wire, low-voltage, CMOS-compatible serial
interface.
The MAX9963/MAX9964 operating range is -1.5V to
+6.5V, with power dissipation of only 825mW per channel.
These devices are available in a 100-pin, 14mm x
14mm body, 0.5mm pitch TQFP with an exposed 8mm
x 8mm die pad on the top (MAX9963) or bottom
(MAX9964) of the package for efficient heat removal.
The MAX9963/MAX9964 are specified to operate with
an internal die temperature of +70°C to +100°C, and
feature a die temperature monitor output.

All MIN and MAX limits are 100% tested in production.
Total for quad device at worst-case setting. RL_ ≥ 10MΩ. The applicable supply currents are measured with typical supply
voltages.
Does not include internal dissipation of the comparator outputs. With output loads of 50Ω to (VVCCO_ _ - 2V), this adds
240mW (typ) to the total chip power (MAX996_ _HCCQ, MAX996_ _JCCQ).
Externally forced voltages may exceed this range provided that the absolute maximum ratings are not exceeded.
Transition time from LLEAK being asserted to leakage current dropping below specified limits.
Transition time from LLEAK being deasserted to output returning to normal operating mode.
Based on simulation results only.
With the exception of offset and gain/CMRR tests, reference input values are calibrated for offset and gain.
Relative to straight line between 0 and 3V.
Full ranges are -1.3V ≤ VDHV_ ≤ 6.5V, -1.5V ≤ VDTV_ ≤ 6.5V, -1.5V ≤ VDLV_ ≤ 6.3V.
Nominal target value is 50Ω. Contact factory for alternate trim selections within the 45Ω to 51Ω range.
V DTV_ = 1.5V, RS = 50Ω. External signal driven into T-line is a 0 to 3V edge with 1.2ns rise time (10% to 90%).
Measurement is made using the comparator.
Measured from the crossing point of DATA_ inputs to the settling of the driver output.
Prop delays are measured from the crossing point of the differential input signals to the 50% point of expected output
swing. Rise time of the differential inputs DATA_ and RCV_ is 250ps (10% to 90%).

Note 15: Rising edge to rising edge or falling edge to falling edge.
Note 16: Specified amplitude is programmed. At this pulse width, the output reaches at least 95% of its nominal (DC) amplitude.
The pulse width is measured at DATA_.
Note 17: Specified amplitude is programmed. Maximum data rate specified in transitions per second. A square wave that reaches
at least 95% of its programmed amplitude may be generated at one-half this frequency.
Note 18: Crosstalk from any driver to the other three channels. Aggressor channel is driving 3VP-P into a 50Ω load. Victim channels
are in term mode with VDTV_ = 1.5V.
Note 19: Indicative of switching speed from DHV_ or DLV_ to DTV_ and DTV_ to DHV_ or DLV_ when VDLV_ < VDTV_ < VDHV_. If
VDTV_ < VDLV_ or VDTV_ > VDHV_, switching speed is degraded by approximately a factor of 3.
Note 20: Both high and low comparators are tested.
Note 21: Change in offset voltage over input range.
Note 22: Change in offset voltage with power supplies independently set to their minimum and maximum values.
Note 23: Unless otherwise noted, all prop delays are measured at 40MHz, VDUT_ = 0 to 2V, VCHV_ = VCLV_ = 1V, slew rate = 2V/ns,
ZS = 50Ω, driver in term mode with VDTV_ = 0V. Comparator outputs are terminated with 50Ω to GND at scope input with
VCCO_ _=2V. Open-collector outputs are also terminated (internally or externally) with RTERM = 50Ω to VCCO_ _. Measured
from VDUT_ crossing calibrated CHV_/CLV_ threshold to the crossing point of differential outputs.
Note 24: VDUT_ = 0 to 1V, VCHV_ = VCLV_ = 0.5V. At this pulse width, the output reaches at least 90% of its DC voltage swing. The
pulse width is measured at the crossing points of the differential outputs.
Note 25: Relative to propagation delay at VCHV_ = VCLV_ = 1.5V. VDUT_ = 200mVP-P. Overdrive = 100mV.

Detailed Description
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 operating 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 terminations. 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 comparator 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 levels to be shared across multiple channels in cost-sensitive systems. A B-grade version provides lower cost for
system designs that incorporate independent reference
levels for each channel.

The driver input is a high-speed multiplexer that selects
one of three voltage inputs, DHV_, DLV_, or DTV_. This
switching is controlled by high-speed inputs DATA_
and RCV_, and mode control bit TMSEL. A slew rate
circuit controls the slew rate of the buffer input. One of
four possible slew rates can be selected (Table 1). The
slew rate of the internal multiplexer sets the 100% driver slew rate (see the Driver Large-Signal Response
graph in the Typical Operating Characteristics).
DUT_ can be toggled at high speed between the buffer
output and high-impedance mode, or it can be placed
in low-leakage mode (Figure 2, Table 2). In high-impedance mode, the clamps are connected. This switching
is controlled by high-speed input RCV_ and mode control bits TMSEL and LLEAK. In high-impedance mode,
the bias current at DUT_ is less than 3µA, while the
node maintains its ability to track high-speed signals. In

low-leakage mode, the bias current at DUT_ is further
reduced to less than 15nA, and signal tracking slows.
The nominal driver output resistance is 50Ω. Contact
the factory for different resistance values within the
45Ω to 51Ω range.
Clamps
A pair of voltage clamps (high and low) can be configured to limit the voltage at DUT_, and to suppress
reflections when the channel is configured as a highimpedance receiver. The clamps behave as diodes
connected to the outputs of high-current buffers.
Internal circuitry compensates for the diode drop at
1mA clamp current. Set the clamp voltages using external connections CPHV_ and CPLV_. The clamps are
enabled only when the driver is in the high-impedance
mode (Figure 2). For transient suppression, set the
clamp voltages to approximately the minimum and
maximum expected DUT_ voltage range. The optimal
clamp voltages are application specific and must be
empirically determined. If clamping is not desired, set
the clamp voltages at least 0.7V outside the expected

DUT_ voltage range; overvoltage protection remains
active without loading DUT_.
Comparators
The MAX9963/MAX9964 have two independent highspeed comparators for each channel. Each comparator
has one input connected internally to DUT_ and the
other input connected to either CHV_ or CLV_
(Figure 1). Comparator outputs are a logical result of
the input conditions, as indicated in Table 3.
Three configurations are available for the comparator
differential outputs to ease interfacing with a wide variety of logic families. An open-collector configuration
switches an 8mA current source between the two outputs. This configuration is available with and without
internal termination resistors connected to VCCO_ _
(Figure 3). For versions without internal termination
resistors, leave V CCO_ _ unconnected and add the
required external resistors. These resistors are typically
50Ω to the pullup voltage at the receiving end of the
output trace. Alternate configurations can be used, provided that the Absolute Maximum Ratings are not
exceeded. For versions with internal terminations, connect VCCO_ _ to the desired VOH voltage. Each output
provides a nominal 400mVP-P swing and 50Ω source
termination.

An open-emitter configuration is also available (Figure

and add external pulldown resistors. These resistors
are typically 50Ω to VCCO_ _ - 2V at the receiving end
of the output trace. Alternate configurations can be
used, provided that the Absolute Maximum Ratings are
not exceeded.
Low-Leakage Mode, LLEAK
Asserting LLEAK through the serial port or with RST
places the MAX9963/MAX9964 into a very-low-leakage
state in which the DUT_ input current is less than 10nA
over the 0 to 3V range. In this mode, the comparators
still function at full speed but the driver and clamps are
disabled. This mode is convenient for making IDDQ
and PMU measurements without the need for an output
disconnect relay. LLEAK is programmed independently
for each channel.
If DUT_ is driven with a high-speed signal while LLEAK
is asserted, leakage current momentarily increases
beyond the limits specified for normal operation. The
low-leakage recovery specification in the Electrical
Characteristics table indicates device behavior under
this condition.
Temperature Monitor
Each device supplies a single temperature output signal, TEMP, that asserts a nominal output voltage of
3.43V at a die temperature of +70°C (343K). The output
voltage increases proportionately with temperature at a
rate of 10mV/°C. The temperature sensor output impedance is 15kΩ (typ).
Driver Termination Select. Set to 1 to
force the driver output to the DTV_
voltage (term mode) when RCV_ = 1. Set
to zero to place the driver into a highimpedance state (high-Z mode) when
RCV_ = 1. See Table 2.

Serial Interface and Device Control
Heat Removal
A CMOS-compatible serial interface controls the
MAX9963/MAX9964 modes (Figure 6). Control data flow
into an 8-bit shift register (MSB first) and are latched
when CS is taken high, as shown in Figure 5. Data from
the shift register are then loaded into any or all of a
group of four quad latches, determined by bits D4
through D7, as indicated in Figure 6 and Table 4. The
quad latches contain the 4 mode bits for each channel
of the quad pin driver. The mode bits, in conjunction
with external inputs DATA_ and RCV_, manage the features of each channel, as shown in Tables 1 and 2. RST
sets LLEAK=1 for all channels, forcing them into lowleakage mode. All other bits are unaffected. At powerup, hold RST low until VCC and VEE have stabilized.
These devices require heat removal under normal circumstances through the exposed pad, either by soldering to circuit board copper (MAX9964) or by use of an
external heat sink (MAX9963). The exposed pad is
electrically at VEE potential for both package types, and
must be either connected to VEE or isolated.
