PRODUCT DESCRIPTION
The ANADIGICS ATA7602 is a -5.2V high speed
transimpedance amplifier (TIA) for 10Gb/s
applications available in bare die form and
manufactured using an InGaP HBT process. The
device is used in conjunction with a photodetector to
convert an optical signal into a differential voltage
that can be AC or DC coupled to a post amplifier.
The DC offset between the two outputs can be adjusted
in order to maintain low dury cycle distortion for large
signal operation or to provide an adjustable decision
threshold for the post amplifier.
