U23 The transmit frame pulse for 8.192 Mbps H-
MVIP signal (TFP8B) references the beginning
of each frame for links configured to operate in
8.192 Mbps H-MVIP mode.
TFP8B references the beginning of a frame for
any link configured for 8.192 Mbps H-MVIP
operation. Only links 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, TFP8B is
sampled on the falling edge of TMV8FPC.
When no links are configured for 8.192 Mbps H-
MVIP operation, TFPB[n] is ignored and should
be tied low.
V22 The transmit 8.192 Mbps H-MVIP frame pulse
clock signal (TMV8FPC) provides the transmit
frame pulse clock for links configured for
operation in 8.192 Mbps H-MVIP mode.
TMV8FPC is used to sample TFP8B.
TMV8FPC is nominally a 50% duty cycle, clock
with a frequency of 4.096 MHz. The falling edge
of TMV8FPC must be aligned with the falling
edge of TMV8DC with no more than ±10 ns
skew.
TMV8FPC[n] is ignored and should be tied low
when no physical links are configured for
operation in 8.192 Mbps H-MVIP mode.
