Cortina releases a low latency chip

Runs 10 Gigabit Ethernet
Tue Mar 16 2010, 11:42

NETWORKING CHIP VENDOR Cortina Systems has announced its CS4315 chip, which is a second-generation electronic dispersion compensation (EDC) device for 10-Gigabit Ethernet.

The outfit said that the chip offers low signal latency along with low power consumption.

The dual-port, quad-CDR PHY and EDC device can support SFP+ 10GBase-SR/LR/LRM and direct-attach copper cable as well as backplane applications.

Both transmit and receive paths include CDR circuits. The analog-based chip can be programmed to enable designers to optimize performance versus power consumption.

The outfit claims that that the CS3415 offers a latency of less than 1ns. This compares rather smashingly with 80ns latency for competing chips and promises to make it useful in Gigabit Ethernet networks. µ

Authorities in several countries raided Megaupload recently, shut down all of its services, seized hundreds of servers and arrested several of its executives on criminal charges.

Do you think the move was justified?
