RJ7xx & RJGn-7xx Schematic 7N1, Rev. I 04 Oct 00
General Features:
-Single Port Through Hole
-Multiport:
1 x 4, 1 x 6, and 1 x 8
-UL Recognized Component;
File # E203973
-Models to Support Most Popular
Phy Chips
-Meets IEEE 802.3 and ANSI X3.263
Requirements.
-Includes integrated LEDs. LED signal
leads are isolated from the Ethernet
signal leads to reduce EMI
and crosstalk.
-Signal routing is designed for NIC
applications. See datasheet
RJ7XX-Schematic 7H1 for Hub signal routing.
-Other signal routing is available. Please
contact the factory at the numbers listed
below.
-Standard LEDs are green. For other
LED options, see the
RJ7XX & RJGn-7XX - LED Options Datasheet.
(xx equals one of the circuit numbers in the table below the schematic and n equals the
number of ports-4, 6, or 8)
