Волоконно-оптические Излучатель / Оптическое волокно излучатель

GENERAL DESCRIPTION of Fiber Optic Emitter / Optical Fiber Emitter HKTX179S is a driver module designed for the application of high-speed optical fiber transmission. It integrates the LED driver with constant current output to reduce the complexity and the cost of the transmission module. HKTX179S can transmit with the speed up to 15Mb/s.It is a replacement of Sharp GP1FA352HT / GP1FSV31TK0F/ GP1FSV51TK0F Features of Fiber Optic Emitter / Optical Fiber Emitter: 1) Conform to EIAJ standard CP-1201 (For Digital audio interfaces including fiber optic inter-connections). 2) TTL interface. 3) LED is drove by differential circuit. 4) Wide range for Supply Voltage (2.7V-5.5V). 5) High speed signal transmission (15M NRZ signal). 6) ESD tolerance IC>8KV. 7) Standard package (panel mount type). Applications of Fiber Optic Emitter / Optical Fiber Emitter:1) Digital audio equipment: CD, MD and DVD player to sound applications for personal computers and computer entertainment systems. 2) Navigation system.
