APPLICATION NOTE
Objective
The objective of this kit is to provide customers with
enough schematic and SPICE parameter information to
perform system level interconnect modeling with the ON
Semiconductor ECLinPS Plus Translator EPT family. The
EPT devices MC100EPT2xD are single or dual supply 1 or
2 Bit translators between the TTL and ECL/PECL worlds.
Single supply devices translate between TTL and PECL,
dual supply devices translate to or from negative supplied
ECL. All devices are designed as 100K compatible
100EPT2x.
The kit contains representative schematics and model
files for the I/O circuits used by the EPT20 and EPT22
devices. The package model should be placed on all external
inputs, outputs and supply pins.
need to be adjusted. The parasitic capacitance and
inductance should be adjusted accordingly.
Modeling
The bias driver schematics for VCS and V1 generation are
not included in this kit, as they are unnecessary for
interconnection simulation. In addition their use would
result in a relatively large in simulation time. Alternatively
the internal reference voltages should be driven with ideal
constant voltage sources.

This model kit is intended for simulations within the
specified power supply range. If supply voltages drop below
minimum specification, VCS and V1 can no longer be
assumed to be constant. Thus, this model kit can not be used
for power up or power down simulations. The 10K ohm
resistor should NOT be simulated as simple SPICE resistor
because it is fabricated by a diffusion step in wafer
processing and there is an associated parasitic. The
following subcircuit should be used to enhance the
performance of the simulation.
Input and Output Schematics
The TTL–PECL Translator function uses circuit
schematics LVTTL01 and LVTTL02 for references
diagrams to the SPICE netlists.
All inputs and outputs of the ELT family are protected by
ESD protection circuitry. The ESD circuit, IN_ESD, is used
for TTL Input and OUT_ESD for PECL outputs.
If the user would like to just simulate the output behavior
of an TTL output the TTL_OUT circuit can be stimulated
with internal signals.
To all external pins the package model, LINES, needs to
be added. If users want to reduce simulation time and just
simulate 1 channel or only the output of a circuit, they need
to take care of the correct power supply management. The
channels share power supply pins. Dynamic ICC current
will add up at power pins. When a simulation is performed
with only one channel, the package models of the power pins
