The PHY1071-01 is a combined VCSEL driver and limiting amplifier with support for digital diagnostic monitoring for use within small form factor modules for Fibre Channel applications.
The transmitter integrates a high-speed output stage with programmable bias and modulation currents, controlled through a 2-wire serial interface. The mean power control loop allows connection in both common cathode and common anode configurations. A loss-of-signal (LOS) detector is included with detection based on either the receiver photo-detector average current or received-signal modulation amplitude.
When used in digital-diagnostics mode, the integrated A/D converters measuring temperature, Tx bias, supply voltage, Rx signal strength and mean power are read through a 2-wire serial interface. An external microcontroller unit (MCU) is used for calibrating real-time diagnostic monitors and alarm generation.
