The SIPO is used to convert the 2.488/2.666 Gbps serial data input to 622.08/666.51 Mbps parallel data output
which can interface to a SONET Framer/ASIC. The SIPO bit de-interleaves the serial data input into a 4-bit
parallel output to RXDO[3:0]P/N. A simplified block diagram is shown in Figure 5.
Receive Serial Input to Parallel Output (SIPO)
2.5
The 4-bit LVDS 622.08/666.51 Mbps parallel data output of the receive path is used to interface to a SONET
Framer/ASIC synchronized to the recovered clock. A simplified block diagram is shown in Figure 6.
