Function
TDD[4]

Transmit Data (TDD[4:1]). When in single-rail
mode, these inputs are the NRZ data signals to
be transmitted. These inputs can be configured
to be active high or active low. These inputs can
be sampled on either the rising or falling edges of
the corresponding TCLKI[4:1].
Transmit Positive Data (TDP[4:1]). When in dual-
rail mode, these inputs are the NRZ positive data
signals to be transmitted. These inputs can be
sampled on either the rising or falling edges of
the corresponding TCLKI[4:1].
TDP[4]

TDP[1]
Input
TDN[4]

TDN[2]
TDN[1]
Input
67
70
73
76
Transmit Negative Data (TDN[4:1]). When in
dual-rail mode, these inputs are the NRZ
negative data signals to be transmitted. These
inputs can be sampled on either the rising or
falling edges of the corresponding TCLKI[4:1].
These input pins are ignored if the device is
configured for single-rail (unipolar) transmit mode.
TCLKI[4]
TCLKI[3]
TCLKI[2]
TCLKI[1]
Input
69

75
78
Transmit Clock (TCLKI[4:1]). This clock should be
1.544 MHz for DS1 or 2.048 MHz for E1 data
streams and is used to sample the corresponding
TDP/TDD[4:1] and TDN[4:1] signals.
RXTIP[4]
RXTIP[3]
RXTIP[2]
RXTIP[1]
Input
64

128
Receive Bipolar Tip (RXTIP[4:1]). The
RXTIP[4:1] inputs are the receive analog positive
pulses. They must be connected to the positive
lead of the transformer secondary through a
passive attenuation network.
RXRING[4]
RXRING[3]
RXRING[2]
RXRING[1]
I/O
63

127
Receive Bipolar Ring (RXRING[4:1]). The
RXRING[4:1] bidirectional pins provide DC bias
to an external isolation transformer. They must
be connected to the negative lead of the
transformer secondary and to a decoupling
capacitor to RAVS[4:1].
