Function
TFP8B
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.
TMV8FPC
Input
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.
