Overview
iT6144 Duobinary Encoder and Driver Amplifier Description The iT6144 is a RoHS-6-compliant integrated duobinary encoder and driver in a compact, surface-mount package for optical 300-pin module and linecard transponders used in long-haul applications.
The device converts an electrical 10 Gb/s NRZ signal into an equivalent duobinary signal, then amplifies it to drive a “filtered” LiNbO3 modulator.
The iT6144’s duobinary output level is adjustable from 6 to 10.
5 Vpp, which is sufficient to reach 2*Vpi of most LiNbO3 modulators and provide margin for loop control to track variations caused by temperature and aging.
Single-ended clock and data inputs eliminate the need for phase-matched traces, simplifying the board layout.
The clock input and duobinary output are AC-coupled in the package.
The data input should be ACcoupled outside the package.
The device is housed in a rugged, RoHS-6-compliant, ceramic package.
Compact duobinary conversion and transmitter drive functions Supports externa...
