Deterministic Latency Options
The HardCopy IV GX device has a deterministic latency option available for use in
high-speed serial interfaces such as CPRI (Common Public Radio Interface). This
option is available in single-width mode with 8/10-bit channel width and
double-width mode with 16/20-bit channel width options only.
