IPtronics releases four-channel TIA and VCSEL driver chip set

JANUARY 27, 2011 -- IPtronics has announced sampling of its quad IPTA12G4C TIA and quad IPVD12G4C VCSEL Driver for pluggable module applications. The chipset is offered as a complement to IPtronics’ existing four-channel offerings that the company says has gained traction for InfiniBand QDR and FDR.

JANUARY 27, 2011 -- IPtronics has announced sampling of its quad IPTA12G4C TIA and quad IPVD12G4C VCSEL Driver for pluggable module applications. The chipset is offered as a complement to IPtronics’ existing four-channel offerings that the company says has gained traction for InfiniBand QDR and FDR.

The IPVD12G4C VCSEL Driver Array and IPTA12G4C TIA/LIA Array are designed to offer advanced features while reducing power dissipation to 0.45 W for the chipset. The 0.45 W figure reflects total power dissipated in the Tx/Rx module or for each cable end, including power in the optics as well as terminations, according to IPtronics.

Channel rates of 12.5 Gbps enable 50-Gbps total bandwidth. With a selectable bandwidth feature the chipset is suitable for multi-rate modules.

IPtronics says the IPxx12G4C chip set is unique because it accommodates both applications for chip-to-chip communications, active cable applications as well as pluggable QSFP+ optical modules without compromising performance, feature-set, or cost. The chipset is fully InfiniBand and Ethernet compliant and includes such functions as on-chip PROM for vendor and start up settings, advanced temperature control features, “any rate” operation by selectable bandwidth, polarity, I2C interface, RSSI, and more.

The low-power features combined with advanced management functions lead to system operational expenditure savings as well as capital expenditure savings, the company asserts.

“Our second-generation four-channel chip set enables a wider use of IPtronics silicon, in particular pluggable modules for QDR InfiniBand and 40G Ethernet applications such as QSFP+ as well as emerging storage applications such as miniSAS,” said Jesper Bek, CEO of IPtronics. "Driven by customer demand, we have spun a revision of our world leading 12 channel chipset with proven performance.”
