S/UNI®-ATLAS-3200 Telecom Standard Product Data Sheet
Preliminary
Pin Name
ICIF_EOP
Type
Input
Pin No Function
(A) not used
(B) not used
(C) RLP_EOP
(C) End of packet. RLP_EOP is used to delineate the packet
boundaries on the RLP_DAT bus. When RLP_EOP is high, the
end of the packet is present on the RLP_DAT bus.
RLP_MOD[1:0] indicates the number of valid bytes the last
double-word is composed of when RLP_EOP is asserted.
RLP_EOP is required to be present at the end of every packet
and is considered valid only when RVAL is asserted.
S/UNI-ATLAS-3200 will always end a transfer at EOP, and
perform a new RLP_SX cycle. As a result, the minimum average
packet size for which OC-48 throughput can be guaranteed is 32
bytes.
(D) TPP_EOP
(D) End of packet. TPP_EOP is used to delineate the packet
boundaries on the TPP_DAT bus. When TPP_EOP is high, the
end of the packet is present on the TPP_DAT bus.
TPP_MOD[1:0] indicates the number of valid bytes the last
double-word is composed of when TPP_EOP is asserted.
TPP_EOP is required to be present at the end of every packet
and is considered valid only when TPP_ENB is asserted.
S/UNI-ATLAS-3200 will always end a transfer at EOP, and
perform a new SX cycle. As a result, the minimum average
packet size for which OC-48 throughput can be guaranteed is xx
bytes. Each transfer requires a separate positive PTPA
response. As a result, the minimum average packet size which
can be guaranteed in single-PHY operation is xx bytes.
