TVCC0
S
+ 5 VDC Power Supply, Port 0 Transmit Driver.
TVCC0 must not vary from TVCC1
or VCC by more than ± 0.3 V.
17
11
TRING0
AO
Transmit Ring, Port 0
. The TTIP and TRING pins are differential driver outputs
designed to drive a 35-200
load. Line matching resistors and transformers can be
selected to give the desired pulse height.

MTIP0
MRING0
AI
AI
Monitor Tip and Ring, Port 0
. These pins monitor tip and ring outputs of either its
own, or those of an adjacent LXT331 on the same board. If the application does not
use this feature, tie one of these pins to a clock source and the other to a mid-level
(referenced to the clock signal) voltage. The clock frequency can range from 100 kHz
to the TCLK frequency.
20
14
DPM0
DO
Driver Performance Monitor, Port 0
. Goes High to indicate the detection of 63
consecutive zeros. Goes Low upon the receipt of a one on the transmit monitor loop
(MTIP/MRING).
21
22
15
16
RTIP0
RRING0
AI
AI
Receive Tip and Ring, Port 0
. RTIP and RRING comprise the receive line interface.
This input pair should be connected to the line through a 1:1 transformer.
23
17
DFM0
DO
Driver Fail Monitor, Port 0
. Goes High to indicate a driver output short condition.

TRING1
AO
Transmit Ring, Port 1
. Refer to TRING0 pin.
30
24
TVCC1
S
+ 5 VDC Power Supply, Port 1 Transmit Driver.
TVCC1 must not deviate from
TVCC0 or VCC by more than ± 0.3 V.
31
25
TGND1
S
Ground, Port 1 Transmit Driver.
Ground return for TVCC1 power supply.
32
26
TTIP1
AO
Transmit Tip, Port 1
. Refer to TTIP0 pin.
33
27
VCC
S
+ 5 VDC Power Supply Input for All Circuits Except Transmit Drivers.
34
28
DFM1
DO
Driver Fail Monitor, Port 1
. Refer to DFM0 pin.
35
29
SPE
DI
Serial Port Enable
(Host mode)
. SPE must be clocked with MCLK, TCLK0 or
TCLK1 to enable Host mode control through the serial port.
LEN01
DI
Line Length Equalizer 0, Port 1
(Hardware mode)
.
Determines the shape and
amplitude of the transmit pulse. Refer to
Table 2 on page 12
36
30
INT1
DO
Interrupt, Port 1
(Host mode).
Refer to INT0 pin.
LEN11
DI
Line Length Equalizer 1, Port 1
(Hardware mode)
.
Determines the shape and
amplitude of the transmit pulse. Refer to
Table 2 on page 12
37
31
PS1
DI
Port Select, Port 1
(Host mode)
. Refer to PS0 pin.
LEN21
DI
Line Length Equalizer 2, Port 1
(Hardware mode)
.
Determines the shape and
amplitude of the transmit pulse. Refer to
Table 2 on page 12
38
32
SDO
DO
Serial Data Output
(Host mode)
.
Read data from the LXT331 registers are output on
this pin. When CLKE is High, SDO is valid on the rising edge of SCLK. When CLKE is
Low, SDO is valid on the falling edge of SCLK.
TAOS1
DI
Transmit All Ones Enable, Port 1
(Hardware mode)
.
Refer to TAOS0 pin.
