Overview
iT6145 Duobinary Encoder and Driver Amplifier (Preliminary Information) Description The iT6145 combines a duobinary encoder, driver amplifier, and fifth-order Bessel lowpass filter in a compact module.
It is designed for use in the transmitters (transponders) of long-haul duobinary optical communication links.
The microchip module is suitable for use in standard 300-pin MSA modules and is housed in a rugged enclosure.
The output of the iT6145 is a duobinary encoded signal with the correct bandwidth and amplitude to directly drive a M-Z optical modulator.
The output level is adjustable from 5 to 9 Vpp to allow for variations in modulator Vpi.
An internal detector provides a temperature-stable DC voltage that is proportional to the output data amplitude, facilitating the use of AGC loops to set the output level.
The clock and data inputs can be driven either differentially for maximum sensitivity, or single ended with the unused inputs terminated in 50 ohms.
