Output Duplication - Quad
The PE-33008 Port expander can provide quad outputs in groups of 16
outputs for SD or HD options. The PE-33008 Port expander functions for
data rates from 270Mb to 1.5 Gb. All outputs are non-inverting. A 128 x 128
Routing switcher could be arranged in the following manner:
• 128 inputs x 112 single outputs and 16 quad outputs - uses 2 port
expanders
or
• 128 inputs x 96 single outputs and 32 quad outputs - uses 4 port
expanders
or
• 128 inputs x 80 single outputs and 48 dual outputs - uses 6 port
expander... etc.
In this application, the eight (8) PE-33008 rear BNCs are used for inputs
(outputs from the router) and all 32 of the front BNCs are used for outputs.

Up to 16 PE-33008 modules can be mounted in an MK-33000 Mounting Kit,
which is 8 RU high and approximately 4 inches (100 mm) deep.
Figure 34 shows a 128 input router with two PE-33008s mounted in an MK-
33000; this provides 112 single outputs and 16 quad outputs. A 256 input
router with 128 single outputs and 128 quad outputs would appear similar
1. All unused connectors must be terminated with 75-ohm terminators; for PE-33008 applications terminators must be supplied
by end-user.
