Receive Equalizer Auto Mode
Disable.
equalizer is turned off from the auto
mode. If zero, the receive equalizer
is turned on and will compensate for
loop length automatically.
Receive Equalization Mid-range.
If one and REDBL is one, the one-
stage equalization is enabled, which
provides approximately 6 dB of
gain. If zero, REDBL or REMAX will
control the receive equalization.
Receive Equalization Maximum. If
one, REDBL is one and REMID is
zero, the two-stage equalization is
enabled,
approximately 12 dB of gain. If zero,
REDBL or REMID will control the
receive equalization.
Unused.
Sign bit. Normalized to a positive
going one, when CPLAt6 is one
then the CPLA0-CPLA5 coefficient
corresponds to a positive level.
When CPLA6 is zero the coefficient
is taken to indicate a negative level.
Pulse shape coefficient for the first
time slot (within one bit cell). CPLA5
is the MSB.
