Photo-link Light Transmitter Unit
PLT137 SERIES
Features
High speed signal transmission（25Mbps NRZ Signal）
TTL interface compatible
+3~+5V single power source
The product itself will remain within RoHS compliant version.
Description
The opto-electrical component is assembled with a 660nm AlGaInP LED and a
driver IC. It transforms the electrical signal to optical signal and be transmitted by
1mm diameter plastic optical fiber.
The component is operated at +3~+5V and has good performance at low
dissipation current, steady light output and efficient light coupling.
Applications
Digital audio equipment
CD player
DVD player
