iC212
HIGHSPEED PHOTORECEIVER
preliminary
Rev A2, Page 2/15
DESCRIPTION
The iC-Haus Highspeed Photoreceiver iC212 has
been developed for optical high speed measurement.
With its bandwidth ranging from DC up to 1.4 GHz
it detects photo signals from constant light to high
speed with rise times down to 280 ps. The iC212
Highspeed Photoreceiver also features offset adjust-
ment to compensate DC levels of the input signal.
The photodiode used offers a spectral range from
320 to 1000 nm with an active area diameter of about
Ø 0.4 mm, which is increased by an Ø 1.5 mm ball
lens, resulting in an effective usable area of typical
0.75 mm². The Highspeed Photoreceiver is able to
detect optical power levels in the sub mW range at
GHz speed.
The iC212 Highspeed Photoreceiver comes with M6
mounting holes for integration in optical bench sys-
tems and an optional fiber-optic input adapter for op-
tical fiber coupling.
