Auxiliary Framer I/O Timing
Transmit and receive timing and data signals are provided by terminals RFRMCK (receive framer clock), RFRM-
DATA (receive framer data), RFS (receive frame sync), RSSFS (receive framer signaling superframe sync), RCRC-
MFS (receive frame CRC-4 multiframe sync), TFS (transmit framer frame sync), TSSFS (transmit framer signaling
superframe sync), TCRCMFS (transmit framer CRC-4 multiframe sync).
The receive signals are synchronized to the recovered receive line clock, RLCK, and the transmit signals are syn-
chronized to the transmit line clock, TLCK. Note that TLCK must be phase locked to the CHI clock, CHICK, see
Table 2. Pin Descriptions, pin D18.
Detailed timing specifications for these signals are given in Figure 17—Figure 24.
