TORX193K

The TORX193K is a kind of fiber optic receiving module for digital audio equipment and navigation system. There are some features of TORX193K as follows: (1)conform to EIAJ standard CP-1201 (for digital audio interface including fiber optic inter-connections); (2) TTL interface; (3)ATC (automatic threshold control) circuit is used for stablized output at wide range of optical power level.

What comes next is about the maximum ratings of TORX193K (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: -150A max ; (3)low level output current, IOL: 1.6 mA max.

The following is about the electrical and optical characteristics of TORX193K (Ta=25, VCC=5 V): (1)data rate: DC to 6 Mb/s max at NRZ code; (2)maximum receivable power, PMAX: -14.5 dBm min when 6 Mb/s, using APF and TOTX193; (3)minimum receivable power, PMIN: -27 dBm max when 6 Mb/s, using APF and TOTX193K; (4)pulse width distortion, tw: -25 ns min and 25 ns max when pulse with 165 ns, pulse cycle 330 ns, using TOTX193, CL=10 pF; (5)current consumption, ICC: 22 mA typ and 40 mA max; (6)high level output voltage, VOH: 2.7 V min; (7)low level output voltage, VOL: 0.4 V max; (6)transmission distance: 0.2 to 10 m using APF.
