Maxim Integrated MAX3956 10GBASE-LR SFP+ optical transceiver IC

Engineers can achieve high performance in optical modules with low power consumption using the highly integrated MAX3956 10GBASE-LR SFP+ optical transceiver IC from Maxim Integrated. The company says the product delivers better than 50% transmit mask margin performance (1 k waveforms, zero mask hits) with <0.8 W total SFP+ module power dissipation. This reduced power dissipation lowers operational expenditures and improves thermal reliability in data centres.

Additionally, the device integrates accurate analog monitors for digital diagnostics monitoring, including temperature, V_CC and RSSI sensors, to ensure a compact design and save bill-of-material cost. By integrating analog monitors and a 12-bit analog-to-digital converter, the product enables the use of an all-digital external microcontroller.

The device is available in a 5 x 5 mm, 32-pin TQFN-EP package. It operates over the -40 to 95°C temperature range.
