Document Table of Contents Word Aligner in Deterministic Latency Mode for CPRI

The deterministic latency state machine in the word aligner reduces the known delay variation from the word alignment process. It automatically synchronizes and aligns the word boundary by slipping one half of a serial clock cycle (1UI) in the deserializer. Incoming data to the word aligner is aligned to the boundary of the word alignment pattern (K28.5).
