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.
