tLTR_LTD_manual is the time the receiver CDR must be kept in lock to reference (LTR) mode after the rx_is_lockedtoref signal goes high when the
CDR is functioning in the manual mode.

The rate matcher supports only up to 300 parts per million (ppm).
The Quartus Prime software allows AC gain setting = 3 for design with data rate between 614 Mbps and 1.25 Gbps only.
