Table 7-5. Hardware Interface Pin Descriptions
NAME
TYPE
FUNCTION
LMn[1:0]
Ipd
LIU Mode Control (Port n). When only the hardware interface is enabled (IFSEL = 000 and
HW = 1), these pins set the LIU mode for port n. See Section 8.1.
00 = DS3
01 = E3
10 = STS-1
11 = reserved
AIST
Ipd
AIS Type Control (All Ports). See Section 8.2.3.
0 = Unframed all ones
1 = Framed DS3 AIS (DS3 mode), unframed all ones (E3 mode), or AIS-L (STS-1 mode)
TAISn
Ipd
Transmit AIS Control (Port n). The type of AIS signal is specified by the LMn[1:0] and AIST
pins. See Section 8.2.3.
0 = transmit normal data
1 = transmit AIS
TBIN
Ipd
Transmit Binary Interface Control (All Ports). See Section 8.2.2.
0 = Transmitter framer interface is bipolar on the TPOS and TNEG pins, and the B3ZS/HDB3
encoder is disabled.
1 = Transmitter framer interface is binary on the
TDAT pin, and the B3ZS/HDB3 encoder is
enabled.
TCC
Ipd
Transmit Common Clock Control (All Ports). When this pin is high, the transmit paths of all
ports are clocked by the TCLK1 pin, and pins TCLKx (x
≠ 1) are ignored. In designs where the
transmit paths of all ports can be clocked synchronously with one another, this mode reduces
wiring complexity between the LIU and the neighboring framer or mapper component. See
Section 8.2.1.
TCLKI
Ipd
Transmit Clock Invert control (All Ports). See Section 8.2.1.
0 = TPOS/
TDAT and TNEG are sampled on the rising edge of TCLK.
1 = TPOS/
TDAT and TNEG are sampled on the falling edge of TCLK.
TDMn
O
Transmit Driver Monitor Status (Port n). This pin reports the status of the transmit driver
monitor. See Section 8.2.9 for more information.
0 = Transmit line driver is operating properly.
1 = Transmit line driver is faulty.
TLBOn
Ipd
Transmit Line Build-Out Control (Port n). This pin specifies cable length for waveform
shaping in DS3 and STS-1 modes. In E3 mode it is ignored and should be wired high or low.
See Section 8.2.6.
0 = Cable length
≥ 225ft
1 = Cable length < 225ft
TOEn
Ipd
Transmitter Output-Enable Control (Port n). This pin enables and disables the transmitter
outputs. The transmitter continues to operate internally when the outputs are disabled; only the
line driver and driver monitor are disabled. See Section 8.2.7.
0 = TXPn/TXNn output drivers disabled (high impedance)
1 = TXPn/TXNn output drivers enabled
TPD
Ipd
Transmit Power-Down (All Ports). See Section 8.2.10.
0 = Enable all transmitters
1 = Power down all transmitters (drivers become high impedance)
