Transmit Parallel Input to Serial Output (PISO)
The PISO is used to convert 77.76 Mbps or 19.44 Mbps parallel data input to 622.08 Mbps STS-12/STM-1 or
155.52 Mbps STS-3/STM-1 serial data output respectively, which can interface to an optical module. The
PISO bit interleaves parallel data input into a serial bit stream taking the first bit from TXDI7, then the first bit
from TXDI6, and so on as shown in Figure 15.
