M02061-12/-21
3.3 or 5 Volt Laser Driver
Rev V6
Applications
Features
• SFP and SFF Modules
• 1G/2G/4G Fibre Channel modules
• Short reach and Metro SONET/SDH
• CPRI: 614.4, 1228.8, 2457.6, 3072.0, 4915.2 and 6144.0 Mbit/s
• OLT Laser Driver for GPON and EPON
• High-speed operation; suitable for SFP/SFF applications.
Typical rise/fall times of 55 ps.
• Programmable temperature compensation. Modulation output and
bias output can be controlled using a few discrete resistors.
• Supports DDMI (SFF-8472) diagnostics
• DC or AC coupled modulation drive. Up to 100 mA modulation
current available when AC coupled.
• Low overshoot allows high extinction ratio with low jitter
• Automatic laser power control, with “Slow-Start”
• PECL and CML compatible differential data inputs
• Complies with major MSAs (GBIC, SFF, SFF-8472, SFP) including
timing requirements
• Packaged in a QFN24
• 3.3 V or 5 V operation
• Pulse width adjustment
The M02061 is a highly integrated, programmable laser driver intended for SFP/SFF modules. Using differential
PECL data inputs, the M02061 supplies the bias and modulation current required to drive an edge-emitting laser.
The modulation output can be DC coupled to the laser diode.
The M02061 includes automatic power control to maintain a constant average laser output power over temperature
and life. In addition, the modulation current can be temperature compensated to minimize variation in extinction
ratio over temperature.
