Iterra iT6144

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.

DESCRIPTION

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 external Bessel filter and pre-filtered modulator applications Adjustable AC coupled output voltage from 6.0 to 10.5 Vpp Power dissipation: 3.3 W with +8 V and -5 V supply voltages Single-ended, AC-coupled data and clock inputs RoHS-6-compliant, 7x8 mm2 (0.278 x 0.315 mil2) SMT ceramic package with bottom pad grounding and heat sinking -5V Supply
