Plastic Fiber Optic Receiver for MOST®

Plastic Fiber Optic Receiver for MOST - 33934 Data Sheet

Description

The 4-pin MOST Optical Receiver (MIR3 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 amplier 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. Excellent solution for converting high speed data from Plastic Optical Fiber (POF) to digital output. ∑ High speed receiver up to 50 MBaud (25Mbit/s net data rate) ∑ TTL Data Output (Light to Logic Function) ∑ Network activity sensing during ZeroPower Mode (I
CC <10µA) ∑ BUS Activity Status Output ∑ Good 650nm sensitivity for working in a low attenuation range of PMMA Fiber ∑ Low cost
