FPSCs from Lattice: ORT82G5/42G5

Lattice Semiconductor has developed the industry's fastest device for high-speed serial backplane data transmission. The ORCA ORT82G5 is made up of backplane transceivers containing eight channels, each operating over a range from 600 Mbits/s to 3.7 Gbits/s, with a full duplex synchronous interface with built-in Clock and Data Recovery (CDR), along with more than 400K FPGA system gates.

The ORT42G5 is made up of backplane transceivers containing four channels, each operating over a range from 600 Mbits/s to 3.7 Gbits/s, along with more than 400K FPGA system gates.

Both the ORT42G5 and ORT82G5 FPSCs offer a clockless high-speed interface for interdevice communication on a board or across a backplane. The built- in clock recovery of the ORT82G5/ORT42G5 allows for higher system performance, easier-to-design clock domains in a multiboard system, and fewer signals on the backplane.

ORT42G5/ORT82G5 Products

Note: The ORT42G5 provides one quad SERDES channel.

Features

• High-speed SERDES with programmable serial data rates from 0.6 Gbits/s to 3.7 Gbits/s.
