MAX3948ETE+ General Description

The MAX3948 is a 3.3V, multirate, low-power laser diode driver designed for Ethernet, Fibre Channel, and SONET transmission systems at data rates up to 11.3Gbps. This device is optimized to drive a differential transmitter optical subassembly (TOSA) with a 25Ω flex circuit. The unique design of the output stage enables DC-coupling to unmatched TOSAs, thereby lowering transmitter power consumption by more than 100mW.

Key Features

Lowest Power Consumption
- 168mW Typical IC Power Dissipation at 3.3V (LD_MOD = 40mA, LD_DC = 20mA)
- 383mW Total Transmitter Power Dissipation at 3.3V Including LD_MOD = 40mA, LD_DC = 20mA
- Enables < 1W Maximum Total SFP+ Module Power Dissipation
- Enables < 2.5W Maximum Total QSFP+ Module Power Dissipation
Saves Board Space
- Small 3mm × 3mm Package
- DC-Coupling to the Laser Reduces External Component Count
Flexibility
- Operate Up to Four MAX3948 ICs Over Single 3-Wire Digital Interface
- Programmable Modulation Current Up to 85mA (5Ω Load)
- Programmable DC Current Up to 61mA (Translates to Up to 100mA Laser Bias Current)
- Programmable Input Equalization and Output Deemphasis
Safety
- Supports SFF-8431 SFP+ MSA and SFF-8472 Digital Diagnostic
- Integrated Eye Safety Features with Maskable Faults
- DC Current Monitor
