GENERAL DESCRIPTION
The function of the S2092 retimer device is to derive
high speed timing signals for DWDM equipment. The
S2092 is implemented using AMCC’s proven Phase
Lock Loop (PLL) technology. Figure 1 shows a typical
network application.
The S2092 can receive a 2.488 Gbps to 2.67 Gbps
scrambled NRZ signal. This range is dependent on
the user's FEC needs and reference frequency selec-
tion. The S2092 recovers the clock from the data
and outputs the retimed data.
The S2092 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.
