iT6145
Duobinary Encoder and Driver Amplifier
(Preliminary Information)
Description
www.DataSheet4U.com
The iT6145 combines a duobinary encoder, driver amplifier, and fifth-order Bessel low-
pass 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.
