A-007186: SerDes Ring VCO does not maintain lock throughout specified temperature range.

Option 1 of the workaround states: ------------------------------------- For all 1.25/2.5/5 GHz protocols, use LC VCO instead of Ring VCO. Rather than selecting the SRDS_PRTCL_Sx in the RCW, use the Alternate SRDS_PRTCL_Sx option. The alternate option has the same functionality as the original option; the only difference being LC VCO rather than Ring VCO.

The alternate Protocols are:

Serdes1: 27 instead of 28 Serdes2: Not impacted Serdes3: 1 instead of 2 Serdes4: 9 instead of 10
