SATURN USER NETWORK INTERFACE (622-MAX)

PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA INC., AND FOR ITS CUSTOMERS’ INTERNAL USE

the jitter tolerance curve between 10 kHz and 30 kHz is due to the clock

difference detector.

The typical jitter tolerance performance of the S/UNI-622-MAX is shown in Figure

3 with the GR-253-CORE jitter tolerance specification limits. The jitter tolerance

setup used a Hewlett Packard HFBR-5208M multi-mode fiber optic transceiver

with approximately -10 dBm input power. The RTYPE register bit in CRSI-622

was set to logic zero.

Note that for frequencies below 300Hz, the jitter tolerance is greater than 22

UIpp; 22UIpp is the maximum jitter tolerance of the test equipment. The dip in

the jitter tolerance curve between 10 kHz and 30 kHz is due to the clock

difference detector.

Serial 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 initial SONET/SDH framing

pattern in the receive stream, and performs serial to parallel conversion on octet

boundaries.
