Jitter Freq. (Hz)

 

 

Note that for frequencies below 300 Hz, the jitter tolerance is greater than 15 UIpp; 15 UIpp is the maximum jitter tolerance of the test equipment. Also note that the dip in the tolerance curve between 300 Hz and 10 kHz is due to the S/UNI-QUAD's internal clock difference detector: if the recovered clock drifts beyond 488 ppm of the reference, the PLL locks to the reference clock.

10.1.2Serial to Parallel Converter

The Serial to Parallel Converter (SIPO) converts the received bit serial stream to a byte serial stream. The SIPO searches for the SONET/SDH framing pattern (A1, A2) in the receive stream, and performs serial to parallel conversion on octet boundaries.

10.2 Receive Section Overhead Processor (RSOP)

The Receive Section Overhead Processor (RSOP) provides frame synchronization, de-scrambling, section level alarm and performance monitoring.

10.2.1Framer

The Framer Block determines the in-frame/out-of-frame status of the receive stream.
