The EL6900C offers significant performance and cost-saving benefits. On-chip real-time power control is provided because the EL6900C includes a two-channel sample-and-hold amplifier that can be programmed for four separate gains under register control. Time and manufacturing costs are further reduced because each channel has an 8-bit calibration DAC to eliminate the need for external potentiometers, normally required for external calibration at manufacturing.

Each channel's 210-MHz clock speed enables up to 3X Blu-Ray Disc write performance. Closed-loop automatic power control (APC) is supported with the EL6900's additional Islope and IAPC inputs. A separate high-current driver for the laser is not needed because the EL6900C contains a high-current output that directly drives current into the blue-violet laser. A digital serial bus makes it easy to program the internal command and data registers. Other features include: programmable amplitude and frequency modulation, low- noise read amplifier, programmable laser slope compensation DAC and programmable laser threshold current DAC.
