SFP+ video controller with dual digital LDD interface from Maxim

Maxim has introduced the DS1876, a SFP+ video controller with a dual laser diode driver (LDD) interface. This interface is designed to control and monitor all transmitter functions for SFP+ optical modules and fully support the SFF-8472 specification. This device controls two laser drivers to enable implementation of modules supporting SDI digital video and other optical video applications.

Automatic power control (APC) and laser modulation is controlled through four temperature-driven look-up tables (LUTs) featuring 10-bit ?-S 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.

Package: 5mm x 5mm 28-pin TQFN

Operating temperature range: -40°C to +95°C

Price: Begins at US$1.75.
