RW8D/RP8D/RA8D Block Can Receive Valid Characters on an Incorrect Character Alignment 2.1.1 Description un e, 20 04 2.1 ur sd ay ,2 4J During normal operation, the Serial Telecom Bus link between devices will be character aligned. If the transmitting device is reset, it is probable that it will restart transmission at a new character alignment. In most cases, the receiving device will detect sufficient LCV density (5 LCVs out of 15 received characters), declare out of character alignment, and proceed to hunt for the new character alignment. ab of sil ico ne xp er to n Th However, there are certain cases where the receiving device will not detect sufficient LCV density when the transmitting device is reset, and subsequently transmits a new character alignment with respect to the receiver's current character alignment. It has been found that sending a constant zero traffic pattern (D0.0+ and D0.0- when encoded) to the serial link will not trigger sufficient LCVs for certain character misalignments. For example, if the character alignment (10 alignments in total) of the transmitting and receiving device is off by 1 bit, the receiving device will detect constant LCVs (9720 LCVs for every frame), in which case, it will hunt for a new character alignment. If the transmitting and receiving device are off by 2 bits, the misalignment will only produce 2 LCVs for every frame. Since the LCV density is less than 5 out of 15 characters, the receiver will not hunt for a new character alignment. This scenario can be observed by polling the LCV counter of the receiving device. It can be seen that the LCV counter will increment slowly as it accumulates LCV at a very slow rate (2 LCVs every frame). led sh eh When the transmitting device sends data with a non-constant traffic pattern, the receiving device will always get sufficient LCV density to go to an out of character alignment, and hunt for a new alignment. A non-constant pattern can be produced by passing live traffic through the devices, or by sending PRBS generated by either the transmitting device or by a tester.

Document No.: PMC-2021842 Issue 2 8 TBSTM Device Errata Released Workarounds AM 2.1.2 20 04 02 :4 9: 08 To address this issue, we recommend forcing the RW8D/RP8D/RA8D decoder block to re-align after a transmitting device is reset, and to verify that the TBS goes back to frame alignment. Additionally, it should be verified that the RW8D/RP8D/RA8D eventually returns to frame alignment following any change of character alignment state. Again, forcing the RW8D/RP8D/RA8D decoder blocks to re-align if frame alignment is not restored is the recommended approach. Re-alignment can be forced by inserting a traffic pattern that causes a high density of LCVs on the receiver or by manually forcing the RW8D/RP8D/RA8D out of character alignment. Each of these possible workaround individually solve the problem and have been verified: Manually force the RW8D/RP8D/RA8D out of character alignment by setting the RW8D/RP8D/RA8D FOCA bit high on the TBS link (Bit 0 of Registers 0x160, 0x170, and 0x180). This will cause the state machine in the TBS to search for a new alignment without relying on receiving LCVs. After forcing out of character alignment, the OFAV should be monitored. If the TSE does not go to frame alignment after two frames, the FOCA bit should be set high again. Note that the FOCA bit should be set low first before setting high as this bit is only effective during a low to high transition. * Have the TBS source non-repeating traffic such as non-constant live or PRBS traffic. When the TBS sources non-repeating traffic, it sends this traffic to the TSE, which in turn sends the traffic back to the TBS. After the TBS receives the non-repeating traffic, any character misalignment between the TSE and TBS will cause the TBS to detect LCV errors. There will be enough LCV error density to force the TBS to hunt for a new character alignment. * Enable Test Pattern Insertion on the TSE link (Bit 3 of Registers 0xNB0, 0xNB8, 0xNC0, and 0xNC8). The TSE can be configured to send a specific 10B code to the TBS. By sending an invalid 10B code (e.g. 0000000000b), the TBS will detect LCVs on every character received and will be forced to hunt for a new character alignment. Once the Test Pattern Insertion is disabled and normal traffic resumes, the RW8D/RP8D/RA8D will align to the new character alignment of the normal traffic. ab Performance With Workaround eh 2.1.3 of sil ico ne xp er to n Th ur sd ay ,2 4J un e, * Performance Without Workaround Occasionally, the TBS and the transmitting device (TSE or another 8B/10B serial capable device) will not have the same character alignment after the transmitting device has reinitialized. This causes erred traffic and LCV Interrupts. The TBS and the transmitting device will not be correctly character aligned until non-constant live or PRBS traffic is passing through the system. After this, the LCV interrupts will disappear. This behavior will only occur when sending a constant repeating pattern (e.g. zero pattern) initially when a transmitting device is reset, and will not occur when sending live or PRBS traffic. Do wn lo ad ed 2.1.4 by k ha led sh The TBS will have the same character alignment as the transmitting device. The transmitting device may be the TSE or another 8B/10B serial capable device such as another TBS or S/UNI(R) MACH48 device. LCV Interrupts will not be triggered. This behavior will only occur when sending a constant repeating pattern (e.g. zero pattern) initially when a transmitting device is reset, and will not occur when sending live or PRBS traffic.
