PHY2210 cable transceiver

Phyworks has introduced the PHY2210 equalizing cable transceiver that enables cable manufacturers to extend the reach and reduce the gauge of active copper cable assemblies supporting all standard data rates up to 10.5Gbit/s.

Integrating a high-performance equalizer, limiting-output amplifier and easily-adjusted pre-emphasis cable driver, the PHY2210 will handle 10G data rates running over 15m of lightweight 24AWG twinax cable.

Provided in a 5mm x 5mm QFN package with a maximum power dissipation of only 500mW, the PHY2210 will particularly benefit SFP+ compliant active cables, where both power capacity and PCB space are limited.

By integrating all receive and transmit functions in a single chip, the device will help reduce the power consumption, overall component count and cost of intra-rack, rack-to-rack and switch-to-switch data center cabling.

Incorporating the two-wire interface required by SFP+ applications, the PHY2210 can be initialized and controlled by either a low-cost microcontroller or just a small EEPROM.

The ability to use the transceiver in a controller-less fashion means lower cost active cable assemblies can be achieved.' The chip needs just a single 3.3V supply and can operate over the temperature range -40C to +85C.

Supporting standard data rates from 1Gbit/s to 10.5Gbit/s, the transceiver provides a single design platform for multiple protocols, helping to significantly reduce product development costs and time to market.

The PHY2210 suits SFP+ active copper cables, Infiniband cables, 6.25G back planes, Fibre Channel (1G, 2G, 4G and 8G) and Ethernet (1G, 10G) networks. The PHY2210 equalizing cable transceiver is supported by a reference module with schematics, BOM and Gerber files, SFP+ host board and GUI.
