2.9.2.7. Rate Match FIFO in Basic (Single Width) Mode
- Select basic (single width) in the RX rate match FIFO mode list.
- Enter values for the following parameters.
Parameter Value Description RX rate match insert/delete +ve pattern (hex) 20 bits of data specified as a hexadecimal string The first 10 bits correspond to the skip pattern and the last 10 bits correspond to the control pattern. The skip pattern must have neutral disparity. RX rate match insert/delete –ve pattern (hex) 20 bits of data specified as a hexadecimal string The first 10 bits correspond to the skip pattern and the last 10 bits correspond to the control pattern. The skip pattern must have neutral disparity. ve (volt encodes) are NRZ_L conditions where +ve encodes 0 and –ve encodes 1. ve is a running disparity (+/–RD) specifically used with the rate matcher. Depending on the ppm difference (which is defined by protocol) between the recovered clock and the local clock, the rate matcher adds or deletes a maximum of four skip patterns (neutral disparity). The net neutrality is conserved even after the skip word insertion or deletion because the control words alternate between positive and negative disparity.
