GENERAL DESCRIPTION
The function of the S3023 clock recovery unit is to
derive high speed timing signals for SONET/SDH-
based equipment. The S3023 is implemented using
AMCC’s proven Phase Locked Loop (PLL) technology.
The S3023 receives either an OC-12/STM-4 or OC-3/
STM-1 scrambled NRZ signal and recovers the clock
from the data. The chip outputs a differential LVPECL
bit clock and retimed data. Figure 1 shows a typical
network application.
The S3023 utilizes an on-chip PLL which consists of
a phase detector, a loop filter, and a voltage con-
trolled oscillator (VCO). The phase detector
compares the phase relationship between the VCO
output and the reference frequency. A loop filter con-
verts the phase detector output into a smooth DC
voltage, and the DC voltage is input to the VCO
whose frequency is varied by this voltage. A block
diagram is shown in Figure 2.
