Product Summary

The EL6935ACL-T13 is a highly integrated laser diode driver designed to support multi-standard writable optical drives. The EL6935ACL-T13 accomplishes this by incorporating a waveform generator wherein the diode currents and timing details can be programmed before operation. The EL6935ACL-T13 inspects the NRZ serial data waveform and generates programmed waveforms in recognition of 3, 4, 5, or 6 or more clock periods of space changing to 3, 4, 5, or 6 or more clock periods of mark, and vice versa. The EL6935ACL-T13 also has an IV amplifier with concurrent read and write sampling. The gains of the IV amplifier are programmable, eliminating the need for external potentiometers.
