DESCRIPTION
Reserved.
Transmit Driver Amplitude Boost:
Adds roughly 5% or 10% of boost to the CMI output. Limits not tested
during production test.
11 : 10% boost
Full Remote (digital) Loopback Enable:
When enabled the recovered receive data is decoded and looped back
to the transmit clock recovery unit exercising the entire receive and
transmit paths.
NOTE: Must be used in conjunction with Serial Plesiochronous Mode or
Serial Loop-Timing Mode.
DESCRIPTION
Reserved.
Transmit Fixed Equalizer Enable:
When enabled, compensates for between 0.75m and 1.5m of FR4 trace
to the serial LVPECL data inputs SIxDP/N
