The MAX3948ETE+T from Analog Devices (Maxim Integrated) is a multirate, low-power laser diode driver capable of data rates up to 11.3Gbps. It is designed for applications such as Ethernet, Fibre Channel, and SONET transmission systems.
This device operates at a voltage range of 2.95V to 3.63V and supports a data rate of 11.3Gbps. It can deliver laser modulation currents of up to 85mA into a 5-ohm differential load and provides programmable DC currents up to 61mA. The MAX3948 features on-chip termination and back termination resistors, and an input equalization block to compensate for host connector losses.
It is housed in a compact 16-TQFN (3x3mm) package with surface mount mounting type. The operating temperature range is -40°C to 95°C. The device supports up to four channels over a single 3-wire digital interface, reducing pin count and external component requirements. Typical IC power dissipation is 168mW at 3.3V with specific modulation and DC current settings.
Applications include 40GBASE-LR4 QSFP+ Optical Transceivers, 10GBASE-LR SFP+ Optical Transceivers, 10GBASE-LRM SFP+ Optical Transceivers, and OC192-SR SFP+ SDH/SONET Transceivers.
