| M02095/6 3.3/5V Laser Driver / Limiting Amplifier for Operation to Gbps The M02095 and M02096 are integrated laser drivers and limiting amplifiers for applications to Gbps and Gbps, respectively. The laser driver modulation output can be AC or DC coupled to an FP/DFB laser. The devices can operate from a 3.3V or 5V supply. The devices include monitors for bias and laser power. 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. PECL or CML outputs are available on the limiting amplifier. Configuration logic provides flexibility in setting data path polarity, safety logic configuration, and LOS behavior. • Gbps STM-16/OC-48 SDH/SONET M02096 • and Gbps Fibre Channel M02095/6 • Gbps Ethernet M02095/6 • Gbps SDH/SONET M02095/6 • Gbps SDH/SONET with FEC M02096 • SDH/SONET 155 Mbps Transceivers • FTTx and Media Converters • High speed operation suitable for applications to Gbps. 55 ps typical rise/fall time into • Independently programmable bias and modulation currents Modulation current to 85 mA and bias current to 100 mA Features con’t • Integrated power supply switch for redundant shutdown under a fault condition • Temperature compensation for modulation current • Automatic Power Control • SFP compliant safety circuitry configurable • mV typical input limiting amp sensitivity at Gbps • CML or 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 3.3V or 5V supply with an internal auto-sensing regulator that enables with 5V supplies and is bypassed with 3.3V supplies • Powers 3.3V ROSAs from its Receiver Regulator output enabling true 3.3/5V designs using all 3.3V Mindspeed TIAs M02095/6 Typical Applications Diagram VCC VCCR VCC3R STSET Clock Data Recovery Unit RxOUTp RxOUTm Output Buffer Regulator Threshold Setting Circuit Limiting Amplifier AC-Coupled RxINp to TIA Vttr RxINm M0201x LOS-ST Offset Cancel Rx_Polarity AC or DC Coupled as described in Applications Information VCC VCCT TCSTART TCSLOPE MODSET LOS-ST_sel LOS Comparator LOS-to-JAM DCR_Disable Modulation Control To Safety Logic DeMux Output Ordering Information Package Operating Temperature M02095G-XX* QFN32 to 95°C M02096G-XX* QFN32 to 95°C * The letter “G” designator after the part number indicates that the device is RoHS-compliant.
