| AMT8312 2.5 Gb/s 850 nm PIN-TIA PRELIMINARY DATA SHEET - Rev 1.0 FEATURES * * * * * * * * 2.5 Gb/s Differential Output TIA 3.3 V Operation 1800 MHz Bandwidth -23 dBm Typical Sensitivity 0 dBm Optical Overload Photocurrent Monitor 100 m 850 nm PIN Photodetector TO-46 5 Pin Lens Package APPLICATIONS * * * * SONET OC-48/SDH STM-16 (2.488 Gb/s) 2 x Fibre Channel (2.125 Gb/s) 2.5 Gb/s Infiniband Fibre Channel/Gigabit Ethernet (1.0625/1.25 Gb/s) T46L TO-46 5 pin Ball Lens Package 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 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.

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. 4 5 VOUTP Ground ELECTRICAL CHARACTERISTICS Table 2: Absolute Maximum Ratings PARAMETER Supply Voltage Optical Input Power Storage Temperature MIN -0.5 - 40 MAX 6.0 +4 + 125 UNIT V dB m C Stresses in excess of the absolute ratings may cause permanent damage. Functional operation is not implied under these conditions. Exposure to absolute ratings for extended periods of time may adversely affect reliability. 2 PRELIMINARY DATA SHEET - Rev 1.0 09/2003 AMT8312 Table 3: Electrical Specifications PARAMETER Wavelength () Detector Diameter S mall S i gnal D i fferenti al Responsi vi ty (@ 100 MHz) (1) Bandwidth (1) Low Frequency Cutoff Output Resistance Optical Overload (2) Optical Sensitivity (2) Maximum Differential Output Voltage TRISE and TFALL (20-80%) (3) Duty Cycle Distortion (4) Total Jitter (4), (5) Supply Current Operating Voltage Range Operating Case Temperature MIN TYP 850 MAX - UNIT nm m V/W MHz kHz dB m dB m mV ps % ps 10000 1500 0 -21 - 100 14500 1800 30 50 -23 550 140 5 60 700 - +3.0 -30 40 +3.3 - 60 +3.6 +105 mA Volts C Notes: (1) Measured at -20 dBm optical input power with output connected into RL = 100 (differential) (2) Measured at 10-10 BER with a 223-1 PRBS at 2.5 Gb/s (3) Measured with a 223-1 PRBS at 2.5 Gb/s, an input optical power of -20 dBm and RL = 100 (differential) (4) Measured with a 223-1 PRBS at 2.5 Gb/s, an input optical power of -3 dBm and RL = 100 (differential) (5) 6 about the center eye crossing.
