9 Application and Implementation

NOTE

Information in the following applications sections is not part of the TI component specification, and TI does not warrant its accuracy or completeness. TI’s customers are responsible for determining suitability of components for their purposes. Customers should validate and test their design implementation to confirm system functionality.

9.1 Application Information

The TLK10002 device can be used to support 10-Gbps data transmission over a backplane, for example, 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 33.

9.2 Typical Application

9.2.1 Design Requirements

Table 62 lists the design parameters of this example.

Table 62. Design Parameters

PARAMETER VALUE
Signaling 9.8304 Gbps
Encoding 8b/10b
REFCLK 122.88 MHz
AC-coupling caps 0.1 µF
Swing 1260 mVpp
Total jitter (max) 0.298 UI

9.2.2 Detailed Design Procedure

The TLK10031 must be powered through a 1-V (nominal) supply on the VDDD, VDDA, DVDD, VDDT, and VPP rails, and by a 1.5-V or 1.8-V (nominal) supply on the VDDR and VDDO rails. The power supply accuracy must be 5% or better, and the user must be careful that resistive losses across the application PCB’s power distribution network do not cause the voltage present at the TLK10002 BGA balls to be below specification. If a switched-mode power supply is used, take care to ensure low supply ripple.
