XRT75R12：Multi-Channel Line Interface Unit (LIU) Family Desynchronizer and Jitter Attenuator with R³ Technology™

Exar's R3 TechnologyTM was first introduced in 2002 as a breakthrough capability delivering key benefits to customers designing interface cards. Devices utilizing the technology are Reconfigurable with integrated clock synthesizer supporting DS3/E3/STS-1 clock rates from a single clock source. This capability enables customers to build one board with a single bill-of-materials, and gives them the agility to quickly respond and reconfigure devices for compressed design cycles. In addition, the series employs Relayless Redundancy eliminating the need for external relays for 1:1 and 1+1 applications by establishing a back-up channel that can be brought on-line in the event of failure.

The first T3/E3/STS-1 products to offer R3 TechnologyTM are the XRT75R03D (three) and XRT75R12D (twelve) Previously, Exar has offered this capability only on its T1/E1 LIU products. Now customers doing T3/E3 designs can take advantage of this unique technology saving time and cost in implementing redundancy as well as supporting global standards for Telecom.
