PRODUCT DESCRIPTION
The ANADIGICS AMT8312, packaged in a 5 pin
TO-46 lens can, is a 3.3 V integrated photodetector
and transimpedance amplifier (TIA) used to convert
a short wavelength (850 nm) input optical signal into
a differential output voltage. The AMT8312 has a
bandwidth of 1.8 GHz, a dynamic range of over
VCC
2
23 dB and a photocurrent monitor with an output that
is proportional to the average input optical power.
These devices are readily designed into receivers,
transceivers and transponders for SONET, Fibre
Channel and Infiniband applications.

DESCRIPTION
Inverted Output Voltage. Logical '0' with an optical input. Needs to be AC
coupled to the load.
Positive Supply Voltage: 3.0 to 3.6 V
Mirrored average photodiode current. The IMON pin is open drain and
should be connected through a 2.0 k resistor to 3.3 V.
Non-Inverted Output Voltage: Logical '1' with an optical input. Needs to be
AC coupled to the load.
Ground: Case is grounded.
