TORX198

The TORX198 is a kind of fiber optic receiving module with analog output to monitor optical flux for simplex digital signal transmission. There are some features of TORX198 as follows: (1)data rate: DC to 6 Mb/s (NRZ mode); (2)TTL interface; (3)ATC (automatic threshold control) circuit is used for stablized output at wide range of optical power level; (4)optical power level; (5)transmission distance: up to 40 m (APF); (6)wide dynamic range; (7)analogue output to monitor optical flux.

What comes next is about the maximum ratings of TORX198 (Ta=25): (1)storage temperature, Tstg: -40 to 85; (2)operating temperature, Topr: -20 to 85; (3)supply voltage, VCC: -0.5 to 7 V; (4)low level output current, IOL: 20 mA; (5)high level output current, IOH: -1 mA; (6)soldering temperature, Tsol: 260. Then is about the recommended operating conditions: (1)supply voltage, VCC: 4.75 V min, 5.0 V typ and 5.25 V max; (2)high level output current, IOH: -60A max ; (3)low level output current, IOL: 1.2 mA max.

The following is about the electrical and optical characteristics of TORX198 (Ta=25, VCC=5 V): (1)data rate: DC to 6 Mb/s max at NRZ code; (2)maximum receivable power, PMAX: -9 dBm min when 6 Mb/s, using APF and TOTX197; (3)minimum receivable power, PMIN: -28 dBm max when 6 Mb/s, using APF and TOTX197; (4)pulse width distortion, tw: -55 ns min and 55 ns max when pulse with 165 ns, pulse cycle 330 ns, CL=10 pF; (5)current consumption, ICC: 22 mA typ and 40 mA max; (6)high level output voltage, VOH: 4.6 V min; (7)low level output voltage, VOL: 0.5 V max; (6)transmission distance: 0.2 to 40 m using APF, TOTX197 and 0.2 to 1000 m when using PCF, TOTX196; (8)analogue output voltage, VOA: 3.4 V min, 3.8 V typ and 4.5 V max at APF, PIN=-9 dBm; 1.2 V min, 1.5 V typ and 1.9 V max at APF, PIN=-28 dBm.
