Jitter
In TE mode, the timing extraction jitter of the ISAC-S conforms to CCITT Recommendation
I.430 (– 7 % to + 7 % of the S-interface bit period).
Description of the Receive PLL (RPLL) of the ISAC-S TE
The receive PLL performs phase tracking each 250 s after detecting the phase between the
F/L transition of the receive signal and the recovered clock. Phase adjustment is done by
adding or subtracting 130 ns to or form a 1.536-MHz clock cycle. The 1.536-MHz clock is than
used to generate any other clock synchronized to the line.
During (re)synchronization an internal reset condition may effect the 1.536-MHz clock to have
high or low times as short as 130 ns. After the S/T-interface frame has achieved the
synchronized state (after three consecutive valid pairs of code violations) the FSC output is set
to a specific phase relationship, thus causing once an irregular FSC timing.
