9 / 18 page LC72722PMS No. A2156-9/18 CCB Input data format (1) Synchronization protection (forward protection) method setting (4bits) : FS0 to FS3 FS3 = 0 : If offset words in the correct order could not be detected continuously during the number of blocks specified by FS0 to FS2, take that to be a lost synchronization sate. FS3 = 1 : If blocks with uncorrectable errors were received consecutively during the number of blocks specified by FS0 to FS2, take that to be a lost synchronization state. F S 0 F S 1 F S 2 Condition for detecting lost synchronization 0 0 0 If 3 consecutive blocks matching the FS3 condition are received. 1 0 0 If 4 consecutive blocks matching the FS3 condition are received. 0 1 0 If 5 consecutive blocks matching the FS3 condition are received. 1 1 0 If 6 consecutive blocks matching the FS3 condition are received. 0 0 1 If 8 consecutive blocks matching the FS3 condition are received. 1 0 1 If 10 consecutive blocks matching the FS3 condition are received. 0 1 1 If 12 consecutive blocks matching the FS3 condition are received. 1 1 1 If 16 consecutive blocks matching the FS3 condition are received. Initial value : FS0 = 0, FS1 = 1, FS2 = 0, FS3 = 0 (2) Synchronization detection method setting (1bit) : BS BS Synchronization detection conditions 0 If during 3 blocks, 2 blocks of offset words were detected in the correct order. 1 If the offset words were detected in the correct order in 2 consecutive blocks.
