Transmit Byte
Uncoded data/control byte to transmit.
The least significant 8 bits of the
pre-coded data transmits in TBI (ten bit
interface) mode.
Input
-
XMIT_x_K
Special Data Indicator
Indicates that Transmit byte is a special
control byte. Must be decoded with
XMIT_x_IDLE to determine action, see
Pre-coded transmit data bit 8 in TBI
mode.
Input
High
XMIT_x_IDLE
Transmit Idle Character
Bar
Transmit an Idle character. Must be
decoded with XMIT_x_K to determine
action, see Table 2-2.
Pre-coded transmit data bit 9 in TBI
mode.
Input
Low
XMIT_x_CLK
Transmit Interface Clock Clock to which transmit interface signals
are timed.
Frequency requirement is dependent on
whether HSE and DDRE are asserted.
configuration options.
Input
-
XMIT_REF_A
Transmit Interface Clock
Select
Indicates that the transmit interface
signals are timed to XMIT_A_CLK
instead of their transmit clock.
Input
High
XCVR_x_DISABLE Transceiver Disable
Indicates that the transmitter and
receiver for this transceiver are disabled.
The link outputs are not driven.
Input
High
XCVR_x_RSEL
Transceiver Link Select
Indicates that the redundant link outputs
are active and that the primary link
outputs are disabled. The primary link
outputs are active and the redundant link
outputs are disabled when this signal is
low. Both sets of outputs may be
simultaneously enabled using the
XMIT_EN_ALL signal.
Input
High
XMIT_EN_ALL
Transmitter Link
Broadcast Enable
Indicates that both the primary and
redundant link outputs are enabled
independent of the assertion of the
XCVR_x_RSEL signal. Broadcast mode
does not override XCVR_x_DISABLE,
which must be set low for transmitter
operation.
Input
High
XMIT_EQ_EN
Transmit Equalization
Enable
Indicates that transmitter equalization is
enabled and that high frequency gain is
applied to the transmitted signal.
