XDOS

Transmit Data Out Sense

0 =

Output signals XDOP/XDON are active low. Output XOID is

active high (normal operation).

1 =

Output signals XDOP/XDON are active high. Output XOID is

active low.

Note: If CMI coding is selected (FMR0.XC(1:0) = 01) this bit has to

be cleared.

The transmit frame marker XFM is independent of this bit.

EQON

Receive Equalizer On

0 =

-10 dB receiver: short-haul mode

1 =

-36 dB receiver: long-haul mode

RLM

Receive Line Monitoring

0 =

Normal receiver mode

1 =

Receiver mode for receive line monitoring;

the receiver sensitivity is increased to detect resistively

attenuated signals of -20 dB (short-haul mode only)

Local Loop

= Normal operation

Local loop active. The local loop-back mode disconnects the

receive lines RL1/RL2 or RDIP/RDIN from the receiver. Instead

of the signals coming from the line the data provided by system

interface is routed through the analog receiver back to the

system interface. The unipolar bit stream is transmitted

undisturbedly on the line. Receiver and transmitter coding must

be identical. Operates in analog and digital line interface mode.

In analog line interface mode data is transferred through the

complete analog receiver.

MAS

Master Mode

= Slave mode

Master mode on. Setting this bit the DCO-R circuitry is

frequency synchronized to the clock (1.544, 2.048 MHz or

kHz, see IPC.SSYF, LIM1.DCOC) supplied by SYNC. If this

pin is connected to V

SS or VDD (or left open and pulled up to VDD

internally) the DCO-R circuitry is centered and no receive jitter

attenuation is performed (only if 1.544 or 2.048 MHz clock is

selected by resetting bit IPC.SSYF). The generated clocks are

stable.
