Microchip Technology EQCO125x40 12.5Gbps Equalizers/Repeaters/Drivers
Microchip Technology EQCO125x40 12.5Gbps Equalizers/Repeaters/Drivers come in a single chip that repeats high-speed 8b/10b coded data signals with a downstream bit-rate between 1.25Gbps to 12.5Gbps. The EQCO125x40 from Microchip Technology uses the same chip at the device (camera) and host (frame grabber) for asymmetric full-duplex communication. These devices can be used as stand-alone cable repeater with simultaneous power and also for downlink and uplink over a single cable. The high-speed direction (or downlink) has a simultaneous complementary uplink, operating at 20.833Mbps or 41.666Mbps 8b/10b coded signaling.The EQCO125x40 family comes in a 16-pin 0.65mm pin pitch and 4mm QFN package. Applications include links for high-definition cameras, links between FPGAs, machine vision, military, aerospace, medical, broadcast and surveillance cameras, and intelligent traffic systems.
Features
- Equalizer for up to 40m of coaxial cable at 12.5Gbps or 130m at 1.25Gbps 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 12.5Gbps downlink
- 21Mbps or 42Mbps uplink
- Power over coax
- Can also be used as a stand-alone cable repeater with simultaneous power and also for downlink and uplink over a single cable
- Integrated termination resistors for differential signaling
- Clock-Data Recovery (CDR) restores signal integrity in both directions
- Both uplink and downlink include an equalizer, CDR, and cable driver
- Reference-clock free operation (no crystal or clock needed)
- Low power consumption / single supply at 1.25V
- 16-pin 0.65mm pin pitch 4mm QFN package
- Small PCB footprint 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, and intelligent traffic systems
- When a single cable carrying power, video data, and camera control stream is needed
