iT6154

9.9 – 12.5 Gb/s NRZ Modulator Driver

The iT6154 is a high-performance NRZ modulator driver for metro and long-haul LiNbO₃

optical transmitters. The device consists of a wideband iTerra pHEMT amplifier in a

surface-mount package. This component is typically used to amplify the data signal

between the transmitter’s MUX and an optical modulator. Its wide output amplitude

range allows the iT6154 to properly drive either electro-absorption (EA) or Mach-

Zehnder modulators.

Description

For system designers requiring a fully functional driver solution the iT6154 includes

essential features such as MSA-compatible supply voltages, low power dissipation,

medium gain, low jitter degradation, and the ability to precisely set the output amplitude

and eye cross point. Additional external components are required for proper operation

such as input and output coupling capacitors, bias choke network, and control circuitry to

adjust the output amplitude and cross point. For lower voltage applications, the iT6154

provides positive bias with an on-chip resistor, which avoids the need for a bias tee or

external choke network. The iT6154 is RoHS compliant and backward compatible with

SnPb soldering.
