Part Number: TLK10232
Hi,
We have used TLK10232 device in one of our design as a XAUI to 10G-KR Converter plus cross-point switch.
Refer to the attached diagram for a high level view of the system.
tlk10232 Block Diagram.jpg
REFCLK used is 156.25MHZ and is connected to REFCLK0.
As shown in the attached block diagram,
- LS side of channel B is left unconnected.
- LS RX of A has to be duplicated on HS TX A & B
- LS TX has to be selected from HS RX A or B based on PRTAD0 pin state or based on MDIO configuration.
Here we have followed the configuration mentioned in app note .tlk10232_BringupProcedures_v2.pdf.
Note below our observations/issues,
1. HS A Link at Switch Fabric A comes up only if LS A (XAUI of Network Processor) is up and configured. Our understanding is that LS and HS sides are independent for Link training. Is this correct or should LS side device be configured and up for the HS side to come up?
2. We are able to establish link and send traffic from Network Processor to Switch Fabric A thru TLK10232 via channel A (LS-A -> HS-A).
3. However, the data switch configuration is not happening properly and hence we are not able to establish data communication between Network Processor & Switch Fabric B via LS-A & HS-B.
Can you share the required configuration to establish data communication between Network Processor & Switch Fabric B via LS-A & HS-B.
Regards,
Rajesh
