EQCO62R20.3 6.25 Gbps Asymmetric Coax Equalizer/
EQCO31R20.3 3.125 Gbps Asymmetric Coax Equalizer
Features
• Complies with the CoaXPress v1.1 camera
standard (1)
• Supports up to 68 meters of cable at 6.25 Gbps
using high-quality coax
• Supports up to 212 meters of cable at 1.25 Gbps
using high-quality coax
• Single-chip solutions for both the camera side and
the frame grabber side, making a bidirectional
connection over a single 75coax cable
• Full-Duplex, bidirectional data channel
- Downlink speeds from 1.25 Gbps up to 6.25
Gbps; differential interfacing straightforward
with internal termination resistors
- Uplink supporting 21 Mbps, allowing
nanoseconds precise triggering events driven
by the frame grabber
• Supports power distribution over the coax up to
900 mA, powering the camera through the same
coax transporting data signals
• Low power consumption (<70 mW, 1.2V supply)
• 16-Pin, 0.65 mm pin pitch, 4 mm QFN package
• Small PCB footprint for EQCO62R20 and off-chip
components, with guaranteed RF-performance
• -40°C to +85°C industrial temperature range
• Pb-free and RoHS compliant
Applications
• High-definition/high-bandwidth links to cameras
• Machine vision for semiconductor chips and
display panel inspection systems
• Military, aerospace, medical applications
• Broadcast and surveillance camera systems
• Traffic license plate and monitoring systems
• High-Speed inspection systems for food Inspection,
bottling inspection, panel inspection, etc.
• Any application requiring a single coax cable
which carries power, video data and camera
control stream.
Introduction
The EQCO62T/R20(2) chipset is a driver/equalizer
chipset that forms a bidirectional, full-duplex
communication link over a single coax cable.
The EQCO62T/R20 chipset is designed to transport up
to 6.25 Gbps over the downlink channel and to trans-
port 21 Mbps over the uplink channel. The
EQCO62T20 is designed to transmit the downlink sig-
nal at up to 6.25 Gbps and receive the uplink signal.
The EQCO62R20 is designed to receive the downlink
signal at up to 6.25 Gbps and to transmit the uplink sig-
nal. Power can be transferred over the same cable via
external inductors.
The chipset is designed to work with several types of
75coaxial cables, including legacy cables as well as
thin, flexible lightweight cables.
Note 1: CoaXPress V1.1 standard. Free down-

2: The EQCO31T20 and EQCO31R20 are
lower-speed versions of the EQCO62T20
and EQCO62R20, with a maximum bit
rate of 3.125 Gbps for the high-speed
downlink and the same uplink speed.

Typical Link Performance
Table 1, Table 2 and Table 3 give an overview of typical
link performance at room temperature for the link
containing the EQCO62T20 coax driver in conjunction
with the EQCO62R20 receiver, using the downlink
channel, uplink channel and power transmission
simultaneously. Performance for EQCO62T/R20 and
EQCO31T/R20 is equal for bit rates up to 3.125 Gbps.
