DESCRIPTION-OPERATION
0 Transmit Clock Inversion (Backplane Interface)
This bit selects whether data transition will happen on the rising or fall-
ing edge of the transmit clock.
0 = Selects data transition happen on the rising edge of the transmit
clocks.
1 = Selects data transition happen on the falling edge of the transmit
clocks.
NOTE: This feature is only available for base rate configuration (i.e.
non-highspeed, or non-multiplexed modes).
2 TxMUXEN
R/W
0 Transmit Multiplexed Mode Enable
This bit enables or disables the multiplexed mode on the transmit side.
When multiplexed mode is enable, four-channel data from the back-
plane interface are multiplexed onto one serial stream and output to the
line side. The backplane speed will be running at 16.384MHz once mul-
tiplexed mode is enabled.
0 = Disables the multiplexed mode.
1 = Enables the multiplexed mode.
