April, 2004 (4.115) (13.97 0.127) 0.100 0.005 (0.457 0.127) long 0.006 0.001 (0.152 0.025) wide 0.142 (3.607) OUTPUT 0.220 (5.588) 0.190 (4.826) GND VCC 0.019 - 0.016 (0.480 - 0.404) 0.100 (2.54) 0.040 (1.016) CAUTION: Do not exceed the absolute maximum soldering temperature and time duration shown in note 1. ALL DIMENSIONS ARE IN INCHES (MILLIMETERS) features * Converts fiber optic signals to TTL digital output * Single 5 V supply * TO-18 header with plastic lens absolute maximum ratings (TA = 25C unless otherwise stated) storage temperature ...................................................................... -40C to +100C operating temperature.................................................................... -40C to +100C lead soldering temperature(1) ......................................................................... 240C supply voltage...................................................................................................... 6V notes: description 1. 1/16" (1.6mm) from case for 5 seconds maximum. The CFR520 is intended for use in 2. For maximum performance, a 0.1F capacitor must be connected between fiber-optic systems and contains an VCC and GND. open collector, digital output, 3. Pulse Width Distortion (PWD) is an increase in output pulse width due to monolithic photo-IC mounted on a optical power, temperature and/or frequency changes and is dependent on TO-18 header. The output allows system conditions. direct interface with TTL circuits. The plastic lens has three crush ribs on the outside of the case to provide definition: inverter - output is LOW when input radiation is above the threshold level. press-fit installation and precise alignment. A microlens is mechanically centered over the photodiode. electrical characteristics (TA = 25C, VCC = 5VDC unless otherwise noted) symbol VCC PIN (peak) ICC VOL VOH tr tf PWD parameter Supply voltage(2) Minimum input sensitivity Supply current Low level output voltage High level output voltage Output rise time Output fall time Pulse width distortion(3) min 4.5 2.4 - typ 2.0 -27.0 13 4.5 0.25 4.5 6.0 6.0 5.0 25 max 5.5 4.0 -14.0 15 6.5 0.5 9.0 9.0 10 35 units V W dBm mA mA V V ns ns % % test conditions P = 850nm into 100/140 m optical fiber, f = 2.5MHz, D.C. = 50%, PWD <10% PIN 3W PIN 0.1W PIN 3W, RL = 560 PIN 0.1W, RL = 560 PIN = 10W, VO = 0.5 to 2.4V RL = 560 PIN = 10W, VO = 2.4 to 0.5V RL = 560 f = 2.5MHz, PIN = 3W peak PIN = 80W peak D.C. = 50% Clairex reserves the right to make changes at any time to improve design and to provide the best possible product.
