Equalizer Bypass
If the incoming signal is attenuated by flat loss only (zero cable loss), the internal equalizer should be bypassed
with MODE1=1, MODE2=1. (See Table 4)
The level of the incoming signal should satisfy the RIN input range
(50mVpk - 1000mVpk for DS3/STS-1).

Clock Acquisition
If a valid input signal is assumed to be already present at the analog input, the maximum time between the
application of device power and error-free operation is typically 20 ms.
