Plastic Fiber Optic Transmitter including Bigfoot™ IC for MOST®
Preliminary Data Sheet
Safety Hints:
Applications of new chip technologies leads to increasing optical efficiency and growing and
higher levels of optical performance. We therefore recommend that the current versions of the
IEC 825-1 and EN 60825-1 standards are taken into account right from the outset, i.e. at the
equipment development stage, and that suitable protection facilities are provided.
The data sheet of the 4-pin MOST Optical Transmitter (MIT3 02) has to be taken as preliminary.
Samples which are delivered before the qualification and the production release are engineering
samples.
Features
Description
Excellent solution for converting high
The MOST BigfootTx Plastic Fiber Optic Transmitter
speed data from TTL to Plastic Optical Fiber is a highly integrated CMOS IC combined with a High
(POF)
speed LED designed to transmit up to 25Mbit/sec
optical data which is biphase coded at up to
•
•
•
•
High speed transmitter up to 50 Mbaud
TTL Data Input (Logic to Light Function)
650 nm for working in a low attenuation
range of PMMA Fiber
High coupled power in1000 micron plastic
fiber
50Mbaud.
The internal peaking circuit minimizes PWD.
The current through the LED will be setup by an
external resistor connected to VCC. This makes it
possible to control the optical output power of the
LED.
• Low cost
