800 Series - RC Networks ECL Terminator Circuits
804 12 Pin SIP ECL
(4612M-804-RC)
Designed to terminate 6 transmission
lines using parallel termination
techniques. Popular resistance values
include 50 or 100 ohms. A 0.1 µF
capacitor is provided for connection
to Vee. Two 0.01 µF capacitors are
provided for connection to Vtt. Values for
R and C not shown in the following table
are available on a custom basis.

805 8, 10 and 12 Pin SIP 100K ECL
(4610H-805-ZoC/CC)
Designed to terminate 6 to 10 trans-
mission lines using Thevenin equivalent
parallel termination techniques in
systems using 100K 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 100K
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.
