Preliminary Data Sheet
The data sheet of the 4-pin MOST Optical Receiver (MIR3 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 4-pin MOST Optical Receiver (MIR3 02) is a
speed data from Plastic Optical Fiber (POF) highly integrated CMOS IC (Bigfoot™) combined with
to digital output.
a high speed PIN - diode designed to receive up to
25Mbit/s optical data which is bi-phase coded at up to
50Mbaud and convert this optical data to a TTL
compatible data stream.
•
High speed receiver up to 50 MBaud
(25Mbit/s net data rate)
This high performance, low cost, CMOS receiver
consists of a low noise transimpedance amplifier and
comparator in the data path. A timer circuit puts the
part into a low power mode if optical data is not
received for 10µs (typ.). During the low power mode,
the PIN diode is still being observed and if activity is
detected, Bigfoot will resume full power operation
within 3.5ms (typ.).

TTL Data Output (Light to Logic Function)
Network activity sensing during
ZeroPower Mode (ICC<10µA)

•
Good 650nm sensitivity for working in a
low attenuation range of PMMA Fiber
Low cost
•
A STATUS-pin indicates if modulated light is received
(Light on -> STATUS = low). With the STATUS-pin
the power supply of the whole MOST device can be
switched ON.
