SPF MYR3 02
Plastic Fiber Optic Receiver for MOST®
Data Sheet
Description
The 4-pin MOST Optical Receiver (MYR3 02) is a highly
integrated CMOS IC combined with 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.
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, The IC will resume full
power operation within 3.5ms (typ.).
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.
