MLX75608 General Description

The 25Mbps Transceiver IC is embedded into a SOIC-type package including both a photo transmitter IC and a photo receiver IC developed for communication on PMMA Plastic Optical Fiber (POF) at a speed up to 25 Mb/s (biphase) or 50 Mb/s (non return to zero).

The optical transmitter houses a LED driver and a 650 nm Light Source die. The Light Source drive current is optimized so that a maximum extinction ratio between the 1 and 0 light levels is obtained. The Light Source modulation current is fully programmable in absolute value over the full temperature range. This feature allows trimming of the optical emitted power within a narrow range at any temperature, hence giving rise to an enhanced optical budget. In addition the trimming capability over temperature allows full compensation of the temperature dependence of the Light Source optical efficiency. In addition also an m3dB function is available (reducing output power with factor of 2).

The optical receiver is implemented as one monolithic Integrated Circuit, which combines with a PIN photo detector with a TIA, limiting amplifier and an LVTTL output stage. This receiver circuit operates at 50Mbps speed and automatically controls its gain over a wide range of optical power.
The optical receiver embeds a wake-up function. When the optical input signal is detected, the circuit puts itself into sleep mode.
The circuit flags its sleeping mode activation via the STATUS pin, which is set at HIGH state. During valid operation, STATUS pin is set at LOW state.
