TXHR_BA
Transmit Half Rate
Selection Bit, Bank
B, Channel A.
When TXHR = 1,
the transmitter sam-
ples data on the fall-
ing edge of the TBC
clock. When TXHR
= 0, the transmitter
samples data on the
falling edge of the
double rate clock
(derived from TBC).
TXHR = 0 on device
reset.
PWRDNT_BA
Transmit Power-
down Control
Bit, Bank B,
Channel A.
When PWRDNT
= 1, sections of
the transmit
hardware are
powered down
to conserve
power.
PWRDNT = 0
on device reset.
PE0_BA
Transmit Pre-
emphasis Selec-
tion Bit 0, Bank
B, Channel A.
PE0, together
with PE1,
selects one of
three preempha-
sis settings for
the transmit sec-
tion. PE0 = 0 on
device reset.
PE1_BA
Transmit Pre-
emphasis Selec-
tion Bit 1, Bank
B, Channel A.
PE1, together
with PE0,
selects one of
three preempha-
sis settings for
the transmit sec-
tion. PE1 = 0 on
device reset.
HAMP_BA
Transmit Half
Amplitude Selec-
tion Bit, Bank B,
Channel A. When
HAMP = 1, the
transmit output
buffer voltage
swing is limited to
half its amplitude.
Otherwise, the
transmit output
buffer maintains
its full voltage
swing. HAMP = 0
on device reset.
TBCKSEL_BA
Transmit Byte
Clock Selection
Bit, Bank B,
Channel A.
When TBCK-
SEL = 0, the
internal XCK is
selected. Other-
wise, the TBC
clock is
selected. TBCK-
SEL = 0 on
device reset.
RSVD
8B10BT_BA
Transmit 8B/
10B Encoder
Enable Bit, Bank
B, Channel A.
When 8B10BT =
1, the 8B/10B
encoder on the
transmit path is
enabled. Other-
wise, it is
bypassed.
8B10BT = 0 on
device reset.
