Transmit Clock for Channels 1–16.
The transmit clock has to be
1.544MHz for T1 or 2.048MHz for E1 mode. TCLKn is the clock used
to sample the data TPOS/TNEG or TDAT on the falling edge. The
expected TCLK can be inverted.
If TCLKn is ‘high’ for 16 or more MCLKs, then transmit all ones
(TAOs) is sent to the line side of the corresponding transmit channel.
When TCLKn starts clocking again, normal operation will begin again
for the corresponding transmit channel.
If TCLKn is ‘low’ for 64 or more MCLKs, then the corresponding
transmit channel on the line side will power-down and be put into high
impedance. When TCLKn starts clocking again the corresponding
transmit channel will power-up and come out of high impedance.
O,
tri-state
Receive Positive Data Output for Channels 1–16.
In dual-rail mode
the NRZ data output indicates a positive pulse on RTIP/RRING. Upon
detecting a LOS, AIS can be inserted if AISEL bit in the
GC
(0F) is set
otherwise the pins will be active. AIS insertion can also be controlled
on an individual LIU basis by
IAISEL
(05) register. If a given receiver is
in power-down mode the associated RPOS pin is high impedance.
Receive Data Output for Channels 1–16.
In single-rail mode, NRZ
data is sent out on this pin. If a given receiver is in power-down mode
the associated RPOS pin is high impedance.
Note:
During an LOS condition, the RPOS/RDATA outputs remain
active.
O,
tri-state
Receive Negative Data Output for Channels 1–16.
In dual-rail
mode the NRZ data output indicates a negative pulse on
RTIP/RRING. Upon detecting a LOS, AIS can be inserted if AISEL bit
in the
GC
is set otherwise the pins will be active. AIS insertion can
also be controlled on an individual LIU basis by
IAISEL
register. If a
given receiver is in power-down mode, the associated RNEG pin is
high impedance.
Code Violation for Channels 1–16.
In single-rail mode, bipolar
violation, code violation, and excessive zeros are reported on CVn. If
HDB3 or B8ZS is not selected, this pin indicates only BPVs. If a given
receiver is in power-down mode, the associated CV pin is high
impedance.
