Lattice Semiconductor
High Speed Data Transmitter
Table 32 specifies serial data output buffer parameters measured on devices with typical and worst case process
parameters and over the full range of operation conditions.
Table 32. Serial Output Timing and Levels (CML I/O)
Transmitter output jitter is a critical parameter to systems with high speed data links. Table 33 and Table 34 specify
the transmitter output jitter for typical and worst case devices over the full range of operating conditions.
