Master Reset Input
Active "High." When this pin is pulled "High" , the internal state
machines are set to their default state.
"Low" = Normal Operation
"High" = Master Hardware Reset

Data Rate Selection
Selects SONET/SDH transmission and reception speed rate
"Low" = STS-3/STM-1 155.52 Mbps
"High" = STS-12/STM-4 622.08 Mbps

Clock Multiplier Unit Reference Frequency Select
This pin is used to select the frequency of the REFCLKP/N or
TTLREFCLK input to the CMU.
"Low" = 77.76 MHz reference clock
"High" = 19.44 MHz reference
clock
NOTE: REFCLKP/N or TTLREFCLK input should be generated
from an LVPECL/LVTTL crystal oscillator which has a
frequency accuracy better than 20ppm in order for the
transmitted data rate frequency to have the necessary
accuracy required for SONET systems..
CDR_BW/VDD
LVTTL,
LVCMOS

15
CDR Bandwidth Select
This pin is used to select the CDR Bandwidth
"Low" = Narrow BW, (Meets SONET jitter transfer requirement)
"High" (VDD) = Wide Band Width.
