Technical Data Sheet
Photo-link Light Transmitter Unit
PLT252 Series
Features
• High speed signal transmission（25Mbps NRZ Signal）
• TTL interface compatible
• +3~+5V single power source
• Pb Free
• The product itself will remain within RoHS compliant version.
Descriptions
The opto-electrical component is assembled with
a 660nm GaAs RCLED 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
• HDMI Digital (192kHz) Audio Interface
