SFP+ Video Controller has dual digital LDD interface.
Press Release Summary:
Model DS1876, with dual laser diode driver (LDD) interface, controls and monitors all transmitter functions for SFP+ optical modules and supports SFF-8472 specification. Automatic power control and laser modulation is controlled through 4 temperature-driven look-up tables with 10-bit DAC outputs. For each driver, unit monitors temperature, VCC, and transmit power and bias current, and also provides I²C-compliant interface to host system. It is specified over -40 to +95°C temperature range.

SFP+ Optical Module Controller with Dual Digital LDD Interface Enables Low-Cost Optical Video Solutions
Maxim's new SFP+ video controller provides all needed control and monitoring functionality for SFF-8472-compliant designs in one 25mm² chip.
SUNNYVALE, CA - Maxim Integrated Products (NASDAQ: MXIM) introduces the DS1876, an SFP+ video controller with a dual laser diode driver (LDD) interface. This device controls and monitors all transmitter functions for SFP+ optical modules and fully supports the SFF-8472 specification. The DS1876 controls two laser drivers to enable low-cost implementation of modules supporting SDI digital video and other optical video applications. This solution gives customers all necessary control and monitoring functionality in a single chip, thus saving the expense of two microcontrollers as well as complex software development.
Automatic power control (APC) and laser modulation is controlled through four temperature-driven look-up tables (LUTs) featuring 10-bit DAC outputs with an independent 72-entry LUT for each output. The DS1876 monitors six analog channels: temperature, VCC, and transmit power and bias current for each of the two laser drivers. It also provides an I2C-compliant interface to the host system.
The DS1876 is fully specified over the -40°C to +95°C temperature range, and is available in a 5mm x 5mm 28-pin TQFN package. Pricing begins at $1.75 (1000-up, FOB USA).
