General Description

The EL6280C is a combination read + 3 write level laser driver and IV amplifier, with an extra read + oscillator ROM channel for use in dual-laser ‘Combo’ drivers. A separate (amplitude and frequency) oscillator modulates the selected output for laser noise reduction during read or write. All these functions are provided in a 24 lead QSOP package.
