Transmit Ground–Port 1. Ground return for transmit driver 1.
Transmit Positive Supply–Port 1. +5 VDC power supply input for transmit driver 1.
Transmit Ring Output–Port 1. See TRING0, pin 12.
Mode 1 Select Input. While CNTL1 is Low, and if this pin is asserted Low, all the LXT334 drivers
are configured for low power mode with a typical peak pulse output voltage of 3 V. If this pin is
asserted High, the LXT334 configures its line drivers for matched line drive mode with a typical
peak pulse output voltage of 4 V. Both the driver and the receivers are set to drive transformers.
If CNTL1 is High, MODE1 controls the load-matching circuitry in the transceiver:
Mode 2 Select Input. If this pin is pulled Low, all transceivers operate in E1 mode using AMI
encoding. With this pin pulled High, all transceivers enter E1 mode using HDB3 encoding if
operated in Unipolar Mode. With this pin left open the LXT334 enters T1 mode according to
Recommendation G.703.
Receive Ring Input–Port 0/Receive TIP Input–Port 0. These pins are the inputs of the fully
differential line receiver.
Loss of Signal Output–Port 0. All LOSx pins are identical. This output is High when the
incoming signal has no transitions, i.e., when it is more than 22 dB below the nominal 0 dB level for
more than 32 consecutive pulse intervals. The LOS condition is cleared and the output pin returns
Low when the incoming signal has transitions (i.e., when the signal level is equal to or greater than
21 dB below the nominal 0 dB level and the average ones density reaches 12.5%.). In data
receiver mode, LOSx is a pure analog energy detector.
In case of a driver fail condition (DFM = High) this pin acts as a Driver Fail Monitor change of
status output to identify the specific driver with the problem.
Receive Ring Input–Port 1/Receive TIP Input–Port 1. See RRING0, pin 19;
RTIP0, pin 20.
Loss of Signal Output–Port 1. See LOS0, pin 21.
Receive Ring Input–Port 2/Receive TIP Input–Port 2. See RRING0, pin 19;
RTIP0, pin 20.
Loss of Signal Output–Port 2. See LOS0, pin 21.
Receive Ring Input–Port 3/Receive TIP Input–Port 3. See RRING0, pin 19;
RTIP0, pin 20.
Loss of Signal Output–Port 3. See LOS0, pin 21.
