The receive frame pulse signals (RFPB[3:0])
reference the beginning of each frame for
the 32 links when configured for operation in
2.048 Mbps H-MVIP mode.
When configured for 2.048 Mbps H-MVIP
operation, the 32 links are partitioned into 4
groups of 8, and each group of 8 links share
a common frame pulse. RFPB[0], RFPB[1],
RFPB[2] and RFPB[3] reference the
beginning of a frame on links RD[7:0],
RD[15:8], RD[23:16] and RD[31:24]
respectively.
When configured for operation in 2.048
Mbps H-MVIP mode, RFPB[n] is sampled
on the falling edge of RMVCK[n].
Otherwise, RFPB[n] is ignored and should
be tied low.
RFP8B
Input
R21
The receive frame pulse for 8.192 Mbps H-
MVIP signal (RFP8B) references the
beginning of each frame for links configured
for operation in 8.192 Mbps H-MVIP mode.
RFP8B references the beginning of a frame
for any link configured for 8.192 Mbps H-
MVIP operation. Only links RD[4m] (0?m?7)
may be configured for 8.192 Mbps H-MVIP
operation.
When one or more links are configured for
8.192 Mbps H-MVIP operation, RFP8B is
sampled on the falling edge of RMV8FPC.
When no links are configured for 8.192
Mbps H-MVIP operation, RFP8B is ignored
and should be tied low.
