M02097 500 Mbps 3.3/5 V LED Driver/Limiting Amplifier
Description
The M02097 is an integrated LED driver and limiting amplifier for applications to 500 Mbps. The LED driver modulation output can be AC or DC coupled to an LED. The device can operate from a 3.3V or 5 V supply. The M02097 includes monitors for bias and modulation current. Integrated safety circuitry provides latched bias and modulation current shutdown if a fault condition is detected and provides an internal VCC switch. The limiting amplifier also includes a programmable signal-level detector, allowing the user to set thresholds at which the logic outputs are enabled. The M02097-11 features a PECL LOS-ST output while the M02097-21 features a CMOS (external pull-up required) LOS-ST output. PECL outputs are available on the limiting amplifier. Configuration logic provides flexibility in setting data path polarity, safety logic configuration, and LOS behavior.
