Receive backplane interface signals include:
RxSERCLK is an input clock at either 12.352MHz or16.384MHz depending on
the selected multiplexed mode.
RxSYNC is an input signal which indicates the multiplexed frame boundary.
The length of RxSYNC depends on the multiplexed mode selected.
RxSER is the high-speed data output
N
OTE
:
In high speed mode, receive data is clocked out on the rising edge of
the 12Mhz or 16MHz clock edge.

Bit-Multiplexed Mode at 12.352MHz is Enabled:
Receive backplane interface is taking data from the four
LIU input channels 0 through 3 and bit-multiplexing the
four-channel data into one 12.352MHz serial stream and
output on channel 0 of the Receive Serial Output
(RxSER). The RxSYNC signal pulses “High” during the
framing bit of each DS-1 frame.
01
Bit-Multiplexed Mode at 16.384MHz is Enabled:
Receive backplane interface is taking data from the four
LIU input channels 0 through 3 and bit-multiplexing the
four-channel data into one 16.384MHz serial stream and
output to channel 0 of the Receive Serial Output
(RxSER). The RxSYNC signal pulses “High” during the
framing bit of each T1 frame.

HMVIP High-Speed Multiplexed Mode Enabled:
Receive backplane interface is taking data from the four
LIU input channels 0 through 3 and byte-multiplexing the
four-channel data into one 16.384MHz serial stream and
output to channel 0 of the Receive Serial Output
(RxSER). The RxSYNC signal pulses “High” during the
last two bits of the previous T1 frame and the first two
bits of the current T1 frame.
11
H.100 High-Speed Multiplexed Mode Enabled:
Receive backplane interface is taking data from the four
LIU input channels 0 through 3 and byte-multiplexing the
four-channel data into one 16.384MHz serial stream and
output to channel 0 of the Receive Serial Output
(RxSER). The RxSYNC signal pulses “High” during the
last bit of the previous T1 frame and the first bit of the
current T1 frame.
