EQCO850SC.3-HS/EQCO875SC.3-HS
1.0 DEVICE OVERVIEW
The EQCO850SC-HS (EQCO875SC-HS) is ideally
suited for simplex and duplex LVDS connections over
50Ω (75Ω) coax cables between 500 Mbps and 1.25
Gbps. For correct operation, the signals must be NRZ
(Non-Return-to-Zero) encoded and DC balanced with a
maximum run length of ten bits. Excellent EMI/RFI
coax cable shielding allows for good EMI properties.
The EQCO850SC-HS operates with a variety of 50Ω
coax cables, including the cost-effective 2.8 mm
diameter RTK cable (e.g. Leoni Dakar 302) commonly
used for radio and navigation antennas in automotive
applications. This cable fits well with the standardized
(DIN and USCAR), high-performance, cost-effective
RF connectors: SAE/USCAR-18 "FAKRA/SMB RF
Connector".
The EQCO875SC-HS is typically useful in situations
where legacy 75Ω cables are present.
Figure 1-1 illustrates a typical LVDS coaxial
connection. It can be used for Gigabit Ethernet
connections over a single coax cable.
