Description

The S1220 device consists of four CDR modules.

Each of the modules can independently run at

the OC-3 or OC-12 data rate. The S1220 can also

be provisioned to mix and match OC-3 and OC-

12 data streams within the same device.

The S1220 can be configured in Media

Independent Interface (MII) mode or in Non-MII

mode.

The S1220 minimizes the external components

on the board: no external loop filter

component, internally biased outputs, internally

provided common mode bias for AC input, and

internally provided bias for external LVPECL

driver.

The S1220 offers significant advantages in

power and real estate savings with high level of

integration, and a small package.

The figure below, System Block Diagram, shows

a typical network application.

Overview

The function of the S1220 clock and data

recovery unit is to derive high speed timing

signals for SONET/SDH-based equipment. The

S1220 receives either an OC-12 or an OC-3

scrambled NRZ signal and recovers the clock

from the data stream. The device outputs a

differential bit clock and retimed data.

The Low Voltage LVDS or LVPECL interfaces

guarantee compliance with the bit-error rate

requirements of the Telcordia and ITU-T

standards.
