Abstract:
An intelligent transmitter module (“ITM”) includes a CDR circuit for equalizing and retiming an electrical data signal, a driver for generating a modulation signal and/or performing waveform shaping of the equalized and retimed signal, and an optical transmitter configured to emit an optical signal representative of the data signal. A linear amplifier may also be included to amplify the modulation signal when the optical transmitter is a laser with managed chirp. Alternately or additionally, a microcontroller with a 14-bit or higher A2D can be included to control and optimize operation of the ITM. In one embodiment, the CDR, driver, linear amplifier, and/or microcontroller are flip chip bonded to a first substrate while the laser with managed chirp is bonded to a second substrate. The first substrate may comprise a multi-layer high frequency laminate.
