GENERAL DESCRIPTION
The function of the S3056 clock recovery unit is to
derive high speed timing signals for SONET/SDH-
based equipment. The S3056 is implemented using
AMCC’s proven Phase Locked Loop (PLL) technology.
Figure 1 shows a typical network application.
The S3056 receives an OC-48, OC-24, OC-12, OC-3,
Fibre Channel or Gigabit Ethernet scrambled NRZ sig-
nal and recovers the clock from the data. The chip
outputs a differential bit clock and retimed data.
The S3056 utilizes an on-chip PLL which consists
of a phase detector, a loop filter, and a Voltage
Controlled Oscillator (VCO). The phase detector
compares the phase relationship between the VCO
output and the serial data input. 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.
