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.
Features
- High-speed operation; suitable for applications to 500 Mbps
- 200 ps typical rise/fall time into 5Ω
- Programmable modulation current to 120 mA
- Integrated power supply switch for redundant shutdown under a fault condition
- Temperature compensation for modulation current
- Pre-bias adjustment to improve LED edge speed
- SFP compliant safety circuitry (configurable)
- 6 mV input limiting amp sensitivity at 500 Mbps
- PECL limiting amplifier outputs
- Limiting amplifier includes integrated DC offset cancellation circuit
- Polarity control for both the driver and limiting amplifier data paths
- Operates with 3.3 V or 5 V supply with an internal auto-sensing regulator that enables with 5 V supplies and is bypassed with 3.3 V supplies
- Powers 3.3 V ROSAs from its receiver regulator output enabling true 3.3/5 V designs using all 3.3 V Mindspeed TIAs
