800 Series - RC Networks ECL Terminator Circuits
801 8, 10 and 12 Pin SIP
(4608M-801-RC/CC)
Designed to terminate 6 to 10 trans-
mission lines using parallel termination
techniques. Standard resistance values
include 50, 68, 75, 82, 90 or 100
ohms and are chosen to match the
characteristic impedance (Zo) of the
transmission line. A 0.01 mF capacitor is
provided to help maintain a solid power
supply level within the network package,
mitigating any cross talk or feedthrough
effects. Values for R and C not shown in
the following table are available on a
custom basis.

802 10 Pin SIP
(4610M-802-RC/CC)
Designed to terminate 6 transmission
lines using parallel termination tech-
niques. Popular resistance values
include 50, 68, 75, 82, 90 or 100
ohms and are chosen to match the
characteristic impedance (Zo) of the
transmission line. Two 0.01 µF
capacitors are provided to reduce cross
talk between lines and to decrease
network package inductance. Values for
R and C not shown in the following table
are available on a custom basis.

803 8, 10 and 12 Pin SIP 10K ECL
(4610H-803-ZoC/CC)
Designed to terminate 6 to 10 trans-
mission lines using Thevenin equivalent
parallel termination techniques in
systems using 10K ECL. Popular
impedance values include 50, 70, 75, 80,
90, 100, 120, 150 or 200 ohms. Standard
values for R1 and R2, based on Zo, have
been chosen to accommodate 10K ECL
designs. A 0.1 µF capacitor is provided
to reduce cross talk noise within the
network package. Values for Zo and C
not shown in the following table are
available on a custom basis. This type of
termination is an alternative to parallel
termination used when a separate Vtt
power supply is not available.
