Step 1: Place the Deserializer in BIST Mode. Serializer and Deserializer power supply must be supplied. Set the Serializer M/S pin to LOW and the Deserializer M/S pin to HIGH. Enable the AT SPEED BIST mode on the De- Freq ...
Page 31
Step 3: Stop at SPEED BIST by turning off BIST mode in the Deserializer to determine Pass/Fail. To end BIST, the system must pull BISTEN pin of the Dese- rializer LOW. The BIST duration is fully defined by the BIS- ...
