Features

• Equalizer for up to 40 m of coaxial cable at

12.5 Gbps or 130 m at 1.25 Gbps over a single

Belden 1694A coax cable

• Same chip used at Device (Camera) and Host

(Frame Grabber) for asymmetric full-duplex

communication

• Lower Cost version EQCO125T40 for Device

(Camera) side only

• Cable types supported are 75  coax, 50  coax,

and 100  STP (Shielded Twisted Pair)

• Simultaneous signaling over a single cable:

- Up to 12.5 Gbps downlink

- 21 or 42 Mbps uplink

- Power over Coax

• Can also be used as a stand-alone cable repeater

with simultaneous power, downlink and uplink

over a single cable

• Integrated termination resistors for differential

signaling

• CDR (Clock-Data Recovery) restores signal

integrity in both directions

• Both Uplink and Downlink include equalizer, CDR

and Cable driver (see Figure 1-2)

• Reference-clock free operation (no crystal or

clock needed)

• Low power consumption / single supply @ 1.25 V

• 16-pin, 0.65 mm pin pitch, 4 mm QFN package

• Small PCB footprint for EQCO125X40 Family with

few off-chip components

• Industrial temperature range

• Pb-free and RoHS compliant

Applications

• CoaXPress compliant systems, supports all

CoaXPress standards and speeds

• Links for high-definition Cameras

• Links between FPGAs

• High-speed capture cards over long cable lengths

• Machine Vision, Military, Aerospace, Medical,

Broadcast and Surveillance cameras, Intelligent

Traffic Systems

• When a single cable carrying power, video data

and camera control stream is needed
