ODIN MIR4 02
Fiber Optic Receiver for MOST®
Data Sheet
Description
The 4-pin MOST Optical Receiver (ODIN MIR4 02) is a
highly integrated CMOS IC combined with a high speed
PIN diode designed to receive up to 25 Mbit/s optical
data which is biphase coded (up to 50 Mbaud) and
convert this optical data to a rail-to-rail data stream.
During the low power mode, the PIN diode is still being
observed and if activity is detected, the receiver will
switch to full power mode. 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. The power supply
voltage is either 3.3V or 5V.

Attention
Stresses above those listed here may cause permanent damage to the device. Exposure to absolute maximum
rating conditions for extended periods may aect device reliability. Between 3.465V and 4.75V the device is not
specied according Table 2. Therefore operation is limited to the range of 3.135V ... 3.465V or 4.75V ... 5.25V.
