Phyworks Transceiver Extends Reach, Reduces Gauge of Copper Cables

The PHY2210 equalizing cable transceiver from Phyworks enables cable manufacturers to extend the reach and reduce the gauge of active copper cable assemblies supporting all standard data rates up to 10.5Gbps. Integrating a high performance equalizer, limiting output amplifier and easily adjusted pre-emphasis cable driver, the PHY2210 will handle 10G datarates running over 15m of lightweight 24AWG twin ax cable.

Provided in a 5x5mm QFN package with a maximum power dissipation of only 0.5W, 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 2-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 -40ºC to +85ºC.
