The transmitter line driver can be disabled and the TXPn and TXNn outputs tri-stated by asserting the LTS
configuration bit (PORT.CR2.LTS). Powering down the transmitter through the TPD configuration bit (CPU bus
mode) also tri-states the TXPn and TXNn outputs.
10.12.4.3 Interfacing to the Line
The transmitter interfaces to the outgoing DS3/E3 coaxial cable (75Ω) through a 2:1 step-down transformer
connected to the TXPn and TXNn pins.
recommended interface components.
10.12.4.4 Transmit Driver Monitor
If the transmit driver monitor detects a faulty transmitter, it sets the PORT.SR.TDM status bit. When the transmitter
is tri-stated, the transmit driver monitor is also disabled. The transmitter is declared to be faulty when the
transmitter outputs see a load of less than ~25Ω.
10.12.4.5 Transmitter Power-Down
To minimize power consumption when the transmitter is not being used, assert the PORT.CR1.PD configuration
bit. When the transmitter is powered down, the TXPn and TXNn pins are put in a high-impedance state and the
transmit amplifiers are powered down.
10.12.4.6 Transmitter Jitter Generation (Intrinsic)
The transmitter meets the jitter generation requirements of all applicable standards, with or without the jitter
attenuator enabled.
10.12.4.7 Transmitter Jitter Transfer
Without the jitter attenuator enabled in the transmit side, the transmitter passes jitter through unchanged. With the
jitter attenuator enabled in the transmit side, the transmitter meets the jitter transfer requirements of all applicable
telecommunication standards. See
