validate and test their design implementation to confirm system functionality.
8.1 Application Information
The TLK10031 device can be used to convert between XAUI (on the low speed port) and 10GBASE-R
signaling (on the high speed port). The high speed side of the device meets the requirements of the
10GBASE-KR physical layer standard for 10 Gbps data transmission over a PCB backplane. The device
can also be used for optical physical layers (like 10GBASE-SR or 10GBASE-LR) by interfacing to optical
modules requiring SFI or XFI electrical signaling. For optical use cases, KR-specific features like Clause
73 auto-negotiation and link training should be disabled.
8.2 Typical Application
A typical application for TLK10031 is to support 10 Gbps Ethernet data transmission over a backplane,
e.g., between a network processor or MAC and switch ASIC located on separate cards within a router
chassis. A block diagram of this application is shown in Figure 8-1.
