GENERAL DESCRIPTION
The function of the S3024 clock recovery unit is to
derive high speed timing signals for SONET/SDH-
based equipment. The S3024 is implemented using
AMCC’s proven Phase Locked Loop (PLL) technology.
The S3024 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 S3024 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 serial data input. A loop filter converts
the phase detector output into a smooth DC voltage,
and the DC voltage is input to the VCO whose fre-
quency is varied by this voltage. A block diagram is
shown in Figure 2.
