Maxim Integrated Products has an optical transmit/receive chipset for data rates 1.0625Gbit/s to 11.3Gbit/s

The devices are the MAX3946 laser driver with impedance-mismatch tolerance and the MAX3945 dual-path limiting amplifier.

This 10GBASE-SR/LR SFP+ transmit/receive chipset enables less than 1W SFP+ optical modules. The combined power consumption of the MAX3946 and MAX3945 is 355mW.

Both ICs include a 3-wire digital control interface with integrated control DACs to reduce external component count. 

The chipset is optimized for Ethernet and Fibre Channel transmission systems at data rates up to 11.3Gbit/s.

The MAX3946 is a 3.3V, multi-rate laser diode driver that is optimized to drive a differential transmitter optical subassembly (TOSA) with a 25ohm flex circuit up to 100mA modulation current and up to 80mA bias current.

The unique design of the output stage enables the use of unmatched TOSAs to reduce headroom limitations and lower module power consumption by 100mW, with only 5psP-P deterministic jitter.

The MAX3945 is a 3.3V, multirate, high-sensitivity limiting amplifier that limits the signal generated by a transimpedance amplifier into a CML-level differential output signal.

The MAX3946 is packaged in a 4mm x 4mm, 24-pin TQFN, and the MAX3945 is offered in a 3mm x 3mm, 16-pin TQFN
