Features
· High speed signal transmission
( 25 Mbps, NRZ signal )
· Input TTL compatible
· +3~+5V power source
Descriptions
The light transmitting unit is a standard-package product with connector and opto-electric component packaged with LED and drive IC. The function of unit changes the electric signal into light signal and be transmitted by plastic fiber.
The unit is operated at single+3V~ +5V and the input signal is TTL compatible. The DLT2160A has a maximum operating speed of 25Mbps. The light signal is coupled into plastic fiber by connector. The unit has high performance at low dissipation current, steady light output and efficient light coupling.
Applications
· Audio equipment
· DVD player/Digical TV player
· PC, Notebook
· Sound card
