Maxim MAX9360EKA-T, MAX9361EKA-T Schematic [ru]

General Description

The MAX9360/MAX9361 are low-skew, single LVTTL/
TTL/CMOS-to-differential LVECL/ECL translators
designed for high-speed signal and clock driver appli­cations. For interfacing to LVTTL/TTL/CMOS input sig­nals, these devices operate over a 3.0V to 5.5V supply
range, allowing high-performance clock or data distrib­ution. For interfacing to differential LVECL/ECL output
signals, these devices operate from a -2.375V to -5.5V
supply.

The MAX9360 is a 3.3V LVTTL/CMOS-to-LVECL/ECL
translator that operates at a typical speed of 3GHz. The
MAX9361 is a 5V TTL/CMOS-to-LVECL/ECL translator
that operates at a typical speed of 1.3GHz. Both
devices can be used to drive either LVECL devices or
standard ECL devices with a negative supply range of

-2.375V to -5.5V.

The devices default to high if the input is disconnected,
and feature ultra-low propagation delay: 440ps for the
MAX9360, 810ps for the MAX9361.

The MAX9360 is specified for operation from -40°C to
+85°C in an 8-pin SO package, and 0°C to +85°C in a
space-saving, 8-pin SOT23 package.

The MAX9361 is specified for operation from -40°C to
+85°C for both 8-pin SO and SOT23 packages.

Detailed Description

The MAX9360/MAX9361 are low-skew, single LVTTL/
CMOS/TTL-to-differential LVECL/ECL translators
designed for high-speed signal and clock driver appli­cations. For interfacing to LVTTL/TTL/CMOS input sig­nals, these devices operate over a 3.0V to 5.5V supply
range, allowing high-performance clock or data distrib­ution in systems with a nominal 3.3V or 5.0V supply. For
interfacing to differential LVECL/ECL output signals,
these devices operate from a -2.375V to -5.5V supply.

The MAX9360 is a 3.3V LVTTL/CMOS-to-LVECL/ECL
translator that operates at typical speeds of 3GHz. The
MAX9361 is a 5V TTL/CMOS-to-LVECL/ECL translator that
operates at typical speeds of 1.3GHz. Both devices can
be used to drive either LVECL devices or standard ECL
devices with a negative supply range of -2.375V to -5.5V.

Input

The MAX9360/MAX9361 inputs accept standard LVTTL/
TTL/CMOS levels. The input has pullup circuitry that dri­ves the outputs to a differential high if the inputs are open.

Differential Output

Output levels are referenced to GND and are considered
ECL or LVECL, depending on the level of the VEEsupply.
With GND connected to zero and VEEat -4.2V to -5.5V,
the outputs are ECL. The outputs are LVECL when GND is
connected to zero and VEEis at -2.375V to -3.8V.

Applications Information

Supply Bypassing

Bypass VCCand VEEto ground with high-frequency
surface-mount ceramic 0.1µF and 0.01µF capacitors in
parallel as close to the device as possible, with the

0.01µF value capacitor closest to the device. Use multi­ple parallel vias for low inductance.

Traces

Input and output trace characteristics affect the perfor­mance of the MAX9360/MAX9361. Connect each signal
of a differential output to a 50Ω characteristic imped­ance trace. Minimize the number of vias to prevent
impedance discontinuities. Reduce reflections by main­taining the 50Ω characteristic impedance through con­nectors and across cables. Reduce skew within a
differential pair by matching the electrical length of the
traces.

On the MAX9360, if the input edge rate approaches the
electrical length of the interconnect, then controlled­impedance transmission lines should be used for the
input traces.

Output Termination

Terminate outputs through 50Ω to -2V or use an equiva­lent Thevenin termination. Terminate both outputs and
use the same termination on each for the lowest output­to-output skew. When a single-ended signal is taken
from a differential output, terminate both outputs. For
example, if Q is used as a single-ended output, termi­nate both Q and Q.

Ensure that the output currents do not exceed the con­tinuous safe output current limit or surge output current
limit as specified in the Absolute Maximum Ratings
table. Under all operating conditions, the device’s total
thermal limits should be observed.
