3.3.3
ADAPTIVE EQUALIZER
The Adaptive Equalizer can be enabled to increase the receive sensi-
tivity and to allow programming of the LOS level up to -24 dB. See3.5 Los
And AIS Detection. It can be enabled or disabled by setting EQ_ON bit to
‘1’ or ‘0’ (RCF1, 0BH).
3.3.4
RECEIVE SENSITIVITY
The Receive Sensitivity is -10 dB. With the Adaptive Equalizer enabled,
the receive sensitivity will be -20 dB.
In Hardware mode, the Adaptive Equalizer can not be enabled and the
receive sensitivity is fixed at -10 dB. Refer to 5 Hardware Control Pin Sum-
mary for details.
3.3.5
DATA SLICER
The Data Slicer is used to generate a standard amplitude mark or a
space according to the amplitude of the input signals. The threshold can
be40%,50%,60%or70%,asselectedbytheSLICE[1:0]bits(RCF2,0CH).
The output of the Data Slicer is forwarded to the CDR (Clock & Data Recov-
ery) unit or to the RDP/RDN pins directly if the CDR is disabled.
3.3.6
CDR (CLOCK & DATA RECOVERY)
The CDR is used to recover the clock and data from the received signal.
The recovered clock tracks the jitter in the data output from the Data Slicer
and keeps the phase relationship between data and clock during the
absence of the incoming pulse. The CDR can also be by-passed in the Dual
Rail mode. When CDR is by-passed, the data from the Data Slicer is output
to the RDP/RDN pins directly.
3.3.7
DECODER
The R_MD[1:0] bits (RCF0, 0AH) are used to select the AMI decoder
or HDB3 decoder.
When the chip is configured by hardware, the operation mode of receive
and transmit path can be selected by setting RXTXM1 and RXTXM0 pins.
Refer to 5 Hardware Control Pin Summary for details.
